Appellant seeks reversal of the trial judge’s decision to revoke his probation.1 He contends that the trial judge erred by (1) relying solely on hearsay evidence that he violated conditions of his probation, (2) applying the wrong standard of proof, (3) relying upon insufficient evidence, and (4) conducting the revocation hearing while he still faced the possibility of being prosecuted for committing a new criminal offense while on probation. We affirm.
I.
Pursuant to an agreement with the government, appellant entered pleas of guilty to armed manslaughter and robbery. For armed manslaughter appellant was sentenced to a term of fifteen years to life with all but seven years suspended and five years probation. For robbery appellant was sentenced to a term of five to fifteen years suspended and five years probation. The sentences were imposed consecutively as to imprisonment and concurrently as to probation. As conditions of probation the trial judge specifically ordered appellant to refrain from using illegal drugs and involving himself in criminal activity.2
Appellant was released on probation on July 25, 1988, approximately three years and seven months after his initial sentencing. Within four months of his release, the probation office reported that appellant had tested positive for illegal drug use on October 25, 1988. In response, the trial judge issued an order to show cause why appellant’s probation should not be revoked. After a hearing on the order to show cause, the trial judge discharged the order and permitted appellant to remain on probation with the condition that he refrain from further drug use. The judge also imposed the condition that appellant complete a drug treatment program with the Alcohol and Drug Abuse Services Administration (“ADASA”).
Within two months, the trial judge received another report disclosing that appellant failed drug tests on November 10, November 28, and December 5, 1988, and that he failed to complete the ADASA surveillance program. The trial judge then issued a second show cause order. Hearings with respect to that order were continued a number of times over the course of the next year.3
On October 23, 1989, appellant was arrested on a charge of armed assault with intent to kill (“AAWIK”). Appellant requested further postponement of his hearing on the drug use violation pending the disposition of the new charge. On December 14, 1989, the AAWIK charge was voluntarily dismissed by the government due to its inability to locate the complaining witness. At the government’s request, the trial judge then issued a third show cause order based upon the allegation that appellant committed a new criminal offense, AAWIK, while on probation.
After evidentiary hearings held in February and March of 1990, the trial judge found that appellant had used illegal drugs and committed a new offense, both of which were violations of conditions of probation.4 As a result, the trial judge revoked appellant’s probation and sentenced him to the remaining unserved time on his sentences. This appeal followed.
*201II.
Appellant contends that the trial judge erred in relying on hearsay evidence in determining whether to revoke his probation for (1) illegal drug use and (2) the commission of a new offense. For the reasons stated below, we find no error with respect to the trial judge’s revocation of appellant’s probation for illegal drug use. Since that violation is sufficient to allow revocation of probation, we do not reach the contentions raised by appellant with respect to the new offense.
A.
Appellant was ordered to show cause why his probation should not be revoked for illegal drug use. At the show cause hearing, the government established that appellant had been using illegal drugs while on probation primarily by presenting the testimony of appellant’s probation officer, Joann Hunter. Her testimony, which was objected to on hearsay grounds, was based upon information reported in appellant’s probation file.
Hunter testified that appellant tested positive for illegal drug use on at least five occasions. Three of the positive results came from tests administered by ADASA on November 10, November 28, and December, 5, 1988. An earlier positive result came from a test administered by ADASA on October 25, 1988, and was the basis for the first show cause order. The fifth positive result came from a drug test administered by the Pretrial Services Agency on June 13, 1989, one of the dates when appellant appeared before the trial judge on the second show cause order.
A copy of the ADASA report disclosing the three positive drug tests in November and December of 1988 was also offered into evidence by the government. The trial judge, noting the report had “sufficient regularity and apparent reliability,” permitted the government to rely on the report over appellant’s objection on hearsay grounds.
Finally, Hunter also testified that on April 10, 1989, during a court proceeding in this case, appellant’s attorney represented that appellant would be entering an inpatient drug treatment program because of his continuing drug problem. At that proceeding, the trial judge also warned appellant that he was running out of chances to deal with his drug problem. Ultimately, appellant was unable to enter that program because he began taking methadone, which made him ineligible.
B.
At the show cause hearings, appellant did not deny using illegal drugs or offer an excuse. Instead, he chose to put the government to its burden of proof. On appeal, he contends the trial judge erred in admitting, over his objection on hearsay grounds, Hunter’s testimony regarding the information contained in his probation file, including the ADASA report. He asserts that because Hunter lacked personal knowledge concerning the information reported in his file, her testimony violated his rights under the confrontation clause.
We observed previously that “[a] probation revocation proceeding is not a criminal prosecution; rather, it is more in the nature of an administrative hearing concerned with the probationer’s rehabilitation.” Short v. United States, 366 A.2d 781, 785 (D.C.1976) (citing Gagnon v. Scarpelli, 411 U.S. 778, 782-785, 93 S.Ct. 1756, 1759-1760, 36 L.Ed.2d 656 (1973) (establishing minimum due process requirements for revocation of probation)). Consequently, the formal rules of evidence governing a criminal prosecution do not apply to a probation revocation proceeding. “[T]he process should be flexible enough to consider evidence including letters, affidavits, and other material that would not be admissible in an adversary criminal trial.” Morrissey v. Brewer, 408 U.S. 471, 489, 92 S.Ct. 2593, 2604, 33 L.Ed.2d 484 (1972) (establishing minimum due process requirements for revocation of parole).5 All that is required before admitting evidence at a *202probation revocation hearing is a determination that the proffered evidence is reliable. Thompson v. United States, 444 A.2d 972, 974 (D.C.1982). Furthermore, the determination that the evidence is reliable satisfies the requirements of the confrontation clause. See Patterson v. United States, 570 A.2d 1198, 1199 footnote (D.C.1990). Thus, “reliable hearsay is admissible in probation revocation hearings,” id. at 1199, and its admission does not violate the confrontation clause, see id. at 1199 footnote.
Hunter testified to the information reported in appellant’s probation file. Probation violation reports have been equated with records admitted pursuant to the business records exception to the hearsay rule; they are “official record[s] kept in the ordinary course of business by the Probation Department.” Patterson v. United States, supra, 570 A.2d at 1199. As such, probation violation reports bear “recognized indi-cia of reliability.” Id. at 1199 (citation omitted). Accordingly, appellant’s hearsay objection to testimony regarding information conveyed by the records contained in his probation file was properly overruled. See id. at 1199.
Appellant also contends that he was deprived of his right to cross-examine a witness on the reliability of the three drug tests administered in November and December of 1988 which disclosed the positive results contained in the ADASA report. Appellant made no attempt to offer any such witness himself. Rather, he asserts that the drug test results were inadmissible because the government did not produce a witness to attest to the accuracy of those three tests.6
We are not persuaded that the trial judge erred when he concluded that the government need not provide a witness who had personal knowledge of the three positive drug tests and who could testify to the reliability of the results. Probation and parole revocation hearings are not trials; the formal rules of evidence do not apply. Consequently, evidence that would be inadmissible at trial may be admissible at a probation or parole revocation hearing. Morrissey, supra, 408 U.S. at 489, 92 S.Ct. at 2604. We are satisfied that in the context of a probation revocation hearing, the ADASA report qualified as sufficiently reliable prima facie evidence that appellant had tested positive for illegal drug use. See Patterson, supra; see also Howard v. United States, 473 A.2d 835, 839-840 (D.C.1984) (chemist report admissible at trial to establish use of controlled substance); Roy v. United States, supra note 6.
Furthermore, appellant never denied using illegal drugs, nor did he ever claim that the test results were erroneous. On the contrary, from the beginning he acknowledged having an ongoing drug problem. He repeatedly requested continuances in order to prove to the court that he could stay drug free, and he asserted that he was attempting to obtain treatment. In sum, appellant’s conduct during the months that the matter was pending was consistent with one who had continued to use illegal drugs as opposed to one who had tested false positive.
Moreover, during the course of the show cause hearing the government inquired whether the trial judge understood appellant’s previous position to be an admission of illegal drug use. The trial judge responded by stating that the illegal drug use was “taken as — as admitted by [appellant] at that point in the case.” Appellant’s counsel responded, “there is no question that we have not contested the fact that [appellant] needed some drug treatment.”
In short, when initially confronted with positive results from numerous drug tests, appellant did not challenge the accuracy of *203the tests. Instead, he maintained for a number of months that he was in need of and that he was seeking treatment for his drug problem. Then, at his revocation hearing, he took the position that the government had failed to prove by competent evidence that he had been using illegal drugs. The trial judge, when determining whether there was any real question as to the reliability of the drug test results, was not obligated to ignore appellant’s prior conduct or statements which were entirely consistent with his continued use of illegal drugs while on probation. Cf. Powell v. United States, 414 A.2d 530, 533 (D.C.1980) (exception to hearsay rule for prior statements that are. inconsistent with a party’s position at trial). Accordingly, we are persuaded the trial judge did not err when he concluded the evidence of appellant’s use of illegal drugs was reliable without requiring testimony regarding the accuracy of the drug tests administered by ADASA.
III.
Appellant also contends the trial judge applied the wrong standard of proof to determine whether he violated a condition of his probation. The decision whether to revoke probation involves a two step inquiry: (1) determining whether a violation has occurred, and if so, (2) determining what action, if any, should be taken as a result. Saunders v. United States, 508 A.2d 92, 95 (D.C.1986) (citations omitted); see Black v. Romano, 471 U.S. 606, 611, 105 S.Ct. 2254, 2257-58, 85 L.Ed.2d 636 (1985). The first determination is essentially a factual one. Id. at 95; see Resper v. United States, 527 A.2d 1257, 1261 (D.C.1987). The second determination is one committed to the sound discretion of the trial judge. Saunders, supra, 508 A.2d at 95. The question of the proper standard of proof, therefore, applies only to the first determination.
The trial judge concluded that he was “reasonably satisfied” appellant had violated two conditions of his probation. He noted that the standard of reasonable satisfaction as applied by him “would be placed on a scale somewhere between a preponderance and clear and convincing.”
The parties agree that this jurisdiction lacks clear authoritative guidance with respect to the appropriate standard of proof for probation revocation proceedings. However, as would be expected, they disagree as to the standard a trial judge should apply. Appellant contends that a violation must be demonstrated by clear and convincing evidence (“clear and convincing”). The government argues that the appropriate standard should be by preponderance of the evidence (“preponderance”). We are persuaded that preponderance is the appropriate minimum standard of proof required for establishing substantive and technical violations of probation.7
A.
The Supreme Court has offered little guidance with respect to the appropriate *204standard. In Morrissey v. Brewer and Gagnon v. Scarpelli, where the Supreme Court prescribed minimum due process requirements for revocation of parole and probation, the Court made clear that “revocation ... is not part of a criminal prosecution and thus the full panoply of rights due a defendant in such a proceeding does not apply.” Morrissey, supra, 408 U.S. at 480, 92 S.Ct. at 2600; see Gagnon, supra, 411 U.S. at 781, 93 S.Ct. at 1759. In establishing those minimum due process requirements, the Court did not mandate a minimum standard of proof for determining, at a final revocation hearing, whether a condition of probation has been violated.8 Moreover, no subsequent opinion of the Supreme Court has established a minimum standard.9 The Supreme Court, however, has indicated that proof beyond a reasonable doubt is not required. See Gagnon, supra, 411 U.S. 789 n. 12, 93 S.Ct. at 1763 n. 12.
This court, in previous cases addressing sufficiency of the evidence in probation revocation proceedings, reviewed the trial judge’s final decision to revoke probation to determine whether that decision was supported by substantial evidence, but did not elaborate on the standard of proof required to establish a violation. See, e.g., Saunders v. United States, supra, 508 A.2d at 96; Jones v. United States, 401 A.2d 473, 478 (D.C.1979). In Jones, this court declined to set aside the trial court’s decision to revoke probation by noting that the decision to revoke probation is “a matter of judicial discretion.” Jones, supra, 401 A.2d at 476-477. We also observed that
the degree of proof required to support a court’s decision to revoke probation is not as great as that required to sustain a conviction for the underlying offense.
Id. at 477. In so doing, the court relied upon three federal courts of appeals cases: United States v. D'Amato, 429 F.2d 1284 (3d Cir.1970); United States v. Carrion, 457 F.2d 808 (9th Cir.1972); and United States v. Markovich, 348 F.2d 238 (2d Cir.1965). In each of those cases, the court held that a probation violation had to be established to the trial judge’s reasonable satisfaction. Our research of the federal authorities reveals that every federal circuit with a reported opinion on this issue applies the reasonable satisfaction standard.10
Although the federal courts of appeal are in agreement as to the applicable standard of proof, they provide little guidance as to what that standard requires. However, at least two of those courts have concluded that the reasonable satisfaction standard requires less compelling proof than the preponderance standard. For example, the Seventh Circuit has held that
[t]he court need only be ‘reasonably satisfied’ and need not find by a preponderance of the evidence that a violation has occurred.
United States v. Torrez-Flores, 624 F.2d 776, 782 (7th Cir.1980) (citation omitted). Also, the Third Circuit declined to reject the reasonable satisfaction standard in fa*205vor of “a stricter standard” of preponderance of the evidence, United States v. Smith, 571 F.2d 370, 372 (3d Cir.1978). Moreover, none of the courts cited defines the standard as requiring more than the preponderance standard.11 Thus, the clear and convincing standard advocated by appellant has no support in the case law of any of the federal courts of appeal.
Although the state courts are not as uniform as the federal courts, they are nearly unanimous in rejecting the clear and convincing standard. Only two states, Minnesota12 and Nebraska,13 apply that standard,14 and Nebraska mandates it by statute.15 In contrast, a survey of the case law of the fifty states after Morrissey and Gagnon reveals that the majority of the states apply or accept the preponderance standard, that many of the remaining states require less, and that only one other state applies a standard that clearly requires more.16 Thus, the clear and convinc*206ing standard has virtually no support in the case law of the fifty states either.
B.
As we have noted, the government requests that we adopt the preponderance standard rather than the clear and convincing standard. We agree with the government for three reasons. First, as we have shown, the overwhelming weight of authority does not support application of the clear and convincing standard. On the other hand, there is substantial authority in support of the preponderance standard. More than half of the states have held that the preponderance standard is the appropriate one to apply. In addition, a substantial number of the remaining states and all of the federal courts of appeal apply a standard that requires less proof than the preponderance standard.
Second, our statute authorizing revocation of probation for adult probationers neither expressly nor implicitly prescribes a standard of proof.17 In addition, the legislative history offers no insight as to what standard of proof the legislature would have a trial judge apply. However, for juvenile proceedings, the legislature has expressly provided that probation may be revoked upon the "establishment of facts alleged by a preponderance of the evidence.” D.C.Code § 16-2327 (1989). We are aware, of course, that the law frequently treats juvenile and adult matters differently. Nevertheless, we see no reason for doing so in probation revocation matters, and in the absence of any expression of legislative intent to the contrary, we are persuaded that adopting the preponderance standard would not violate any expressed public policy.
Third, the probationer’s liberty interest in avoiding incarceration, like that of the parolee, is constitutionally significant. Morrissey, supra, 408 U.S. at 480, 92 S.Ct. at 2599-2600; Gagnon, supra, 411 U.S. at 782, 93 S.Ct. at 1759-60. As the Supreme *207Court stated, “[i]mplicit in the system’s concern with parole violations is the notion that the parolee is entitled to retain his liberty as long as he substantially abides by the conditions of his parole.” Morrissey, supra, 408 U.S. at 479, 92 S.Ct. at 2599. The court, therefore, must “insure that his liberty is not unjustifiably taken away.” Gagnon, supra, 411 U.S. at 785, 93 S.Ct. at 1761. However, the probationer’s liberty interest is a conditional one and thus does not entitle him to the same degree of due process otherwise afforded a citizen.
Confinement of a probation violator is based upon commission of the criminal offense which the [government] was required to prove beyond a reasonable doubt. Probation rather than incarceration at the time of conviction is a matter of grace which may be withdrawn when the violator is shown, [by a preponderance of evidence] not to have honored the conditions made known at the time probation was granted.
Wink v. State, 317 Md. 330, 563 A.2d 414, 420 (1989). Moreover, the government’s interest is not confined to “unnecessarily interrupting a successful effort at rehabilitation.” The government also has an important interest in not “imprudently prejudicing the safety of the community.” Gagnon, supra, 411 U.S. at 785, 93 S.Ct. at 1761. We conclude that the application of the preponderance standard achieves the required “final evaluation of any contested relevant facts” 18 and most appropriately protects the interests of both the government and the probationer.19
Accordingly, for the reasons stated, we hold that the standard of proof required to establish a substantive violation of probation is preponderance of the evidence.20 As we explain in part IV, we do not reach the issue whether the preponderance standard also applies for a violation based upon the commission of a new offense. In this case, the trial judge applied a standard that required more than a preponderance of the evidence. Appellant, therefore, cannot now complain because the trial judge applied a standard requiring the government to make a stronger showing than necessary.21
IV.
With respect to the evidence presented regarding the new offense, appellant makes the same three arguments previously addressed with respect to the illegal drug use. Specifically, he contends the trial judge improperly admitted hearsay evidence, applied the wrong standard of proof, and based the finding that he committed the offense on insufficient evidence. Appellant also contends that the trial judge erred in conducting a hearing to determine whether he committed a new offense while he still faced the possibility of being tried for committing that offense.22 We do not consider appellant’s claims of error with respect to the new offense because we are *208satisfied, as we have already stated, that there was an adequate basis for the trial court to conclude that appellant violated his probation by using illegal drugs. That finding alone was sufficient to permit the trial judge to proceed to the next step.
Our dissenting colleague ostensibly acknowledges that probation revocation is a two-step process, but misidentifies the steps. The first step, which consists of fact-finding, is to determine whether the defendant has violated the terms of his probation. If the answer is yes, then the second (discretionary) step is to determine what should be done about the fact that the defendant has violated his probation — in other words, what (if any) sanction should be imposed.23
In this case, the trial judge found two “first-step” violations: the commission of the new offense and the renewed drug use. Even if the new offense evidence is not considered, the finding of a second violation — unlawful drug use — was made by the judge. That finding was not a part of the second, discretionary step, but rather a part of the fact-finding first step. By noting that the trial judge has made this finding, we are not, as Judge Ferren suggests, substituting our discretion for the trial judge’s. Rather, we are noting a historical fact — the trial judge has found that appellant violated his probation by using illegal drugs.
Once it is understood that a finding of probation violation has been made, all that remains is the second, discretionary step. As we will now demonstrate, there is no question that the trial judge properly considered for sentencing purposes the hearsay testimony regarding the commission of the new offense. See Johnson v. United States, 508 A.2d 910, 911 (D.C.1985).
The law has long been settled that the rules of evidence applicable at trial do not restrict a trial judge when considering information for purposes of determining an appropriate sentence. Nearly half a century ago, the Supreme Court concluded that “[t]he due process clause should not be treated as a device for freezing the evidential procedure of sentencing in the world of trial procedure.” Williams v. New York, 337 U.S. 241, 251, 69 S.Ct. 1079, 1085, 93 L.Ed. 1337 (1949).
Highly relevant — if not essential — to [a sentencing judge’s] selection of an appropriate sentence is the possession of the fullest information possible concerning the defendant’s life and characteristics. And modern concepts individualizing punishment have made it all the more necessary that a sentencing judge not be denied the opportunity to obtain pertinent information by a requirement of rigid adherence to restrictive rules of evidence properly applicable to the trial.
Id. at 247, 69 S.Ct. at 1083. “[M]ost of the information now relied upon by judges to guide them in the intelligent imposition of sentences would be unavailable if information were restricted to that given in court by witnesses subject to cross-examination.” Id. at 250, 69 S.Ct. at 1084. Accordingly, in determining what sentence to impose, the trial judge “may appropriately conduct an inquiry broad in scope, largely unlimited either as to kind of information he may consider, or the source from which it came.” United States v. Tucker, 404 U.S. 443, 446, 92 S.Ct. 589, 591, 30 L.Ed.2d 592 (1972); Roberts v. United States, 445 U.S. 552, 556, 100 S.Ct. 1358, 1362, 63 L.Ed.2d 622 (1980).
Notwithstanding the very broad discretion afforded the trial judge in conducting a sentencing proceeding, the judge’s discretion has limitations. The trial judge “may not rely on mistaken information or baseless assumptions.” United States v. Hamid, 531 A.2d 628, 644 (D.C.1987) (citations omitted); see Townsend v. Burke, 334 U.S. 736, 68 S.Ct. 1252, 92 L.Ed. 1690 (1948). Rather, as this court has held, the sentencing judge may rely on any reliable evidence. Williams v. United States, 427 A.2d 901, 904 (D.C.1980) (emphasis added).
*209In Powers v. United States, 588 A.2d 1166 (D.C.1991), we held that the trial judge could properly rely upon a prosecutor’s proffer that the defendant had committed an uncharged robbery because the proffer was “ ‘supported by sufficiently reliable information.’ ” Id. at 1172 (citation omitted). In reaching that conclusion, this court noted that there were inherent similarities between the uncharged robbery and the three robbery charges to which Powers pleaded guilty. Id. at 1171. We also noted that Powers did not show “that the government’s proffer regarding the [uncharged robbery] was altogether lacking in reliability, i.e., was misinformation or a baseless assumption.” Id. at 1171.
In this case, a police officer testified that both the complaining witness and an eyewitness identified appellant from a photo array as the man who shot the complaining witness while he was using a pay phone. The officer also testified that each witness related essentially the same facts concerning the events of the shooting. Therefore, as in Powers, we cannot conclude that the evidence presented by the government to establish that appellant committed a new offense was baseless. While it is true that appellant disputed the allegation by offering evidence to rebut the testimony presented by the police officer, that did not render the government’s evidence unreliable.24 We conclude that the government’s evidence was sufficiently reliable to merit consideration by the trial judge for the purposes of deciding whether to revoke appellant’s probation and to impose an appropriate sentence.25
Judge Ferren would “remand the case for a new probation revocation hearing and a new exercise of discretion.” Such a remand would serve no purpose. Once the case was returned to him, the trial judge would undoubtedly recognize that he has already found that appellant violated probation. So far as the “exercise of discretion” is concerned, the trial judge would be aware that he could consider, for sentencing purposes, the hearsay evidence that appellant committed the new offense. The exercise of discretion that Judge Ferren would have the trial judge undertake on remand would therefore be identical to the exercise which he previously undertook when he initially ordered appellant to serve the suspended portion of his previously imposed sentence. As we recently reiterated, we will not order a remand to require a trial judge to perform for symbolic purposes an essentially futile act. In re Melton, 597 A.2d 892, 908 (D.C.1991) (en banc).
Accordingly, the judgment of the trial court is
Affirmed.
