OPINION
delivered the opinion of the court,
in which WILLIAM B. CAIN and PATRICIA J. COTTRELL, JJ., joined.
This appeal involves a dispute between a prisoner and the Tennessee Department of Correction regarding the Department’s decision to classify the prisoner as a multiple rapist under Tenn.Code Ann. § 39-13-523(b) (2000). After the Commissioner of Correction denied his petition for a declaratory order, the prisoner filed a petition for a declaratory judgment in the Chan-eery Court for Davidson County claiming that the Department had misclassified him and, if it had not, that he was still entitled to earn sentence reduction credits because he was a Range I standard offender. The trial court dismissed the petition, and the prisoner has appealed. We have determined that the Department properly classified the prisoner as a multiple rapist and that the prisoner is not otherwise entitled to earn sentence reduction credits. Accordingly, we affirm the trial court’s judgment.
I.
Raymond Mitchell, dubbed the “Fantasy Man” by the Nashville news media,1 was indicted on three counts of rape accomplished by fraud and one count of attempted rape. One of the rape charges was severed prior to trial. A Davidson County jury convicted him of two counts of rape and one count of attempted rape, and on June 19, 1996, the Criminal Court for Davidson County sentenced him as a Range I standard offender to two concurrent ten-year sentences for the rape convictions and one consecutive five-year sentence for the attempted rape conviction. Mr. Mitchell later pleaded nolo contendere to the severed rape charge, and the Criminal Court for Davidson County imposed a two-year sentence for sexual battery to be served concurrently with the sentences already imposed. Accordingly, Mr. Mitchell received a total effective sentence of fifteen years.
The Department of Correction classified Mr. Mitchell as a “multiple rapist,” thereby preventing him from earning credits to shorten his sentence.2 Mr. Mitchell peti*564tioned the Commissioner of Correction for a declaratory order that he was entitled to use his credits to reduce his sentence. After the Commissioner determined that he was properly classified,3 Mr. Mitchell filed a petition for a declaratory judgment in the Chancery Court for Davidson County insisting that he was entitled to earn sentence reduction credits based on his treatment as a Range I standard offender and the Criminal Court’s comments during the sentencing hearing that he would be eligible for parole after serving thirty percent of his sentence and that he would be able to earn sentence reduction credits to reduce the length of his sentence even more.
The Office of the Attorney General and Reporter moved to dismiss Mr. Mitchell’s petition. Unfortunately, as is so often the case with motions filed by assistant attorneys general, this motion failed to comply with Tenn. R. Civ. P. 7.02 by stating with particularity the grounds for the motion.4 Based on Mr. Mitchell’s response to the motion, we presume that the motion was a Tenn. R. Civ. P. 12.02(6) motion asserting that Mr. Mitchell had failed to state a claim upon which relief could be granted because he has been properly classified as a multiple rapist. On January 17, 2001, the trial court filed a memorandum opinion and order dismissing Mr. Mitchell’s petition.

Standard of Review
The sole purpose of a Tenn. R. Civ. P. 12.02(6) motion to dismiss is to test the sufficiency of the complaint, not the strength of the plaintiffs evidence. Doe v. Sundquist, 2 S.W.3d 919, 922 (Tenn.1999); Bell ex rel. Snyder v. Icard, Merrill, Cullis, Timm, Furen & Ginsburg, P.A., 986 S.W.2d 550, 554 (Tenn.1999). It requires the courts to review the complaint alone, Daniel v. Hardin County Gen. Hosp., 971 S.W.2d 21, 23 (Tenn.Ct.App.1997), and to look to the complaint’s substance rather than its form. Kaylor v. Bradley, 912 S.W.2d 728, 731 (Tenn.Ct.App.1995). Dismissal under Tenn. R. Civ. P. 12.02(6) is warranted only when the alleged facts will not entitle the plaintiff to relief or when the complaint is totally lacking in clarity and specificity. Dobbs v. Guenther, 846 S.W.2d 270, 273 (Tenn.Ct.App.1992).
A Tenn. R. Civ. P. 12.02(6) motion admits the truth of all the relevant and material factual allegations in the complaint but asserts that no cause of action arises from these facts. Winchester v. Lit *565 tle, 996 S.W.2d 818, 821 (Tenn.Ct.App.1998); Smith v. First Union Nat’l Bank, 958 S.W.2d 113, 114 (Tenn.Ct.App.1997). Accordingly, courts reviewing a complaint being tested by a Tenn. R. Civ. P. 12.02(6) motion must construe the complaint liberally in favor of the plaintiff by taking all factual allegations in the complaint as true, Stein v. Davidson Hotel, 945 S.W.2d 714, 716 (Tenn.1997), and by giving the plaintiff the benefit of all the inferences that can be reasonably drawn from the pleaded facts. Robert Banks, Jr. & June F. Entman, Tennessee Civil Procedure § 5 — 6(g), at 254 (1999). On appeal from an order granting a Tenn. R. Civ. P. 12.02(6) motion, we must likewise presume that the factual allegations in the complaint are true, and we must review the trial court’s legal conclusions regarding the adequacy of the complaint without a presumption of correctness. Bell ex rel. Snyder v. Icard, Merrill, Cullis, Timm, Furen & Ginsburg, P.A., 986 S.W.2d at 554; Stein v. Davidson Hotel, 945 S.W.2d at 716.

MR. Mitchell’s Classification as a Multiple Rapist
Mr. Mitchell claims that the Department’s decision to classify him as a multiple rapist renders his sentence invalid and is inconsistent with Tenn.Code Ann. § 40-35-106 (2000). The trial court properly declined to consider Mr. Mitchell’s various challenges to the validity of his sentence5 because declaratory proceedings under Tenn.Code Ann. § 4-5-225 (1998) cannot be used to challenge the validity of a criminal conviction or sentence.6 Therefore, the only issue properly before the trial court and this court is whether the Department properly construed and applied Tenn.Code Ann. § 39-13-523(b) to Mr. Mitchell. We have determined that it did.
Mr. Mitchell asserts that the Department interpreted Tenn.Code Ann. § 39-13-523(b) incorrectly because it failed to consider it in pari materia with TenmCode Ann. § 40-35-106(b)(4) which provides:
Convictions for multiple felonies committed as part of a single course of conduct within twenty-four (24) hours, constitute one (1) conviction for the purpose of determining prior convictions; however, acts resulting in bodily injury or threatened bodily injury to the victim or victims shall not be construed to be a single course of conduct.
This argument is without merit for at least three reasons. First, the statutes do not deal with the same subject matter. Tenn. Code Ann. § 39-13-523(b) relates to sentence reduction credits; while Tenn.Code Ann. § 40 — 35—106(b)(4) relates to the sentence itself. Therefore, these statutes *566need not be construed in pari materia.7 Second, because specific statutes control over more general ones,8 Tenn.Code Ann. § 39-13-523(b) that deals specifically with sentence reduction credits for multiple rapists controls over Tenn.Code Ann. § 40-35 — 106(b)(4) to the extent they are inconsistent. Finally, Tenn.Code Ann. § 40-35-106(b)(4) does not apply to Mr. Mitchell because (1) the acts for which he was convieted-rape-resulted by their very nature in bodily injury to their victims and (2) the rapes were not part of a single course of conduct within a twenty-four hour period.
Mr. Mitchell also asserts that he is entitled to earn sentence reduction credits despite Tenn.Code Ann. § 39-13-523(b) because he was sentenced as a Range I standard offender and because the judgment order does not specifically state that he is not entitled to earn sentence reduction credits. We have already addressed this issue in a case involving a child rapist.9 There, we pointed out that “[t]he judgment of the trial court quite correctly says nothing at all relative to sentence reduction credits since administration of such statutory sentence reduction credits is committed by the General Assembly to the Department of Corree-tions.” Rutherford, v. Campbell, 2000 WL 679235, at * 1.
Tenn.Code Ann. § 39-13-523(b) was enacted in 199210 and thus was part of the substantive law when Mr. Mitchell committed his offenses between August 1992 and July 1994. Accordingly, it was part of his sentence when he was tried and convicted of multiple rapes in 1996. The Department had no discretion regarding the application of Tenn. Code Ann. § 39-13-523(b) to Mr. Mitchell in light of his two rape convictions. Accordingly, the Department did not err by classifying Mr. Mitchell as a “multiple rapist” for the purpose of Tenn.Code Ann. § 39 — 13—523(b) and by determining that he wras ineligible to earn sentence reduction credits.11
IV.
We affirm the order dismissing Mr. Mitchell’s petition for a declaratory judgment and remand the case to the trial court for whatever further proceedings may be required. We tax the costs of this appeal to Raymond Mitchell for which execution, if necessary, may issue. We also have determined that this appeal is frivolous in accordance with Tenn.Code Ann. *567§ 41-21-807(c) (Supp.2001) and Tenn.Code Ann. § 41-21-816(a)(1) (1997).
