delivered the opinion of the Court.
This appeal raises issues similar to those decided in Parham v. J. R., ante, p. 584, as to what process is due when the parents or guardian of a child seek state institutional mental health care.
I
This is the second time we have reviewed a District Court’s judgment that Pennsylvania’s procedures for the voluntary admission of mentally ill and mentally retarded children to a state hospital are unconstitutional. In the earlier suit, five children who were between the ages of 15 and 18 challenged the 1966 statute pursuant to which they had been admitted to Haverford State Hospital. Pa. Stat. Ann., Tit. 50, §§ 4402, 4403 (Purdon 1969). After a three-judge District Court, with one judge dissenting, declared the statute unconstitutional, Bartley v. Kremens, 402 F. Supp. 1039 (ED Pa. 1975), the Pennsylvania Legislature amended its mental health code with regard to the mentally ill. The amendments placed *642adolescents over the age of 14 in essentially the same position as adults for purposes of a voluntary admission. Mental Health Procedures Act of 1976, § 201, Pa. Stat. Ann., Tit. 50, § 7201 (Purdon Supp. 1978). Under the new statute, the named plaintiffs could obtain their requested releases from the state hospitals independently of the constitutionality of the 1966 statute, and we therefore held that the claims of the named plaintiffs were moot. Kremens v. Bartley, 431 U. S. 119, 129 (1977). We then remanded the case to the District Court for “reconsideration of the class definition, exclusion of those whose claims are moot, and substitution of class representatives with live claims.” Id., at 135.
On remand, 12 new plaintiffs, appellees here, were named to represent classes of mentally ill and mentally retarded children. Nine of the children were younger than 14 and constituted all of those who had been admitted to the State’s hospitals for the mentally ill in accordance with the 1976 Act at the time the suit was brought; three other children represented a class of patients who were 18 and younger and who had been or would be admitted to a state hospital for the mentally retarded under the 1966 Act and 1973 regulations implementing that Act. All 12 children had been admitted on the application of parents or someone standing in loco parentis with state approval after an independent medical examination.
The suit was filed against several named defendants, the Pennsylvania Secretary of Public Welfare and the directors of three state owned and operated facilities. The District Court, however, certified a defendant class that consisted of “ 'directors of all mental health and mental retardation facilities in Pennsylvania which are subject to regulation by the defendant Secretary of Public Welfare.’ ” 459 F. Supp. 30, 40 n. 37 (ED Pa. 1978).1
*643Representatives of the nine mentally ill children sought a declaration that the admission procedures embodied in § 2012 of the Pennsylvania Mental Health Procedures Act of 1976, Pa. Stat. Ann., Tit. 50, § 7201 (Purdon Supp. 1978), which subsequently have been expanded by regulations promulgated by the Secretary of Public Welfare, 8 Pa. Bull. 2432 et seq. (1978), violated their procedural due process rights and requested the court to issue an injunction against the statute’s future enforcement. The three mentally retarded children presented the same claims as to §§ 4023 and 4034 of the *644Mental Health and Mental Retardation Act of 1966, Pa. Stat. Ann., Tit. 50, §§ 4402 and 4403 (Purdon 1969), and the regulations promulgated thereunder.5
The District Court certified two subclasses of plaintiffs 6 *645under Fed. Rule Civ. Proc. 23 and held that the statutes challenged by each subclass were unconstitutional. It held that the State’s procedures were insufficient to satisfy the Due Process Clause of the Fourteenth Amendment.
The District Court’s analysis in this case was similar to that used by the District Court in J. L. v. Parham, 412 F. Supp. 112 (MD Ga. 1976), reversed and remanded sub nom. Parham v. J. R., ante, p. 584. The court in this case concluded that these children had a constitutionally protected liberty interest that could not be “waived” by their parents. This conclusion, coupled with the perceived fallibility of psychiatric diagnosis, led the court to hold that only a formal adversary hearing could suffice to protect the children in appellees’ class from being needlessly confined in mental hospitals.
To further protect the children’s interests, the court concluded that the following procedures were required before any child could be admitted voluntarily to a mental hospital:
1) 48-hour notice prior to any hearing;
2) legal counsel “during all significant stages of the commitment process”;
3) the child’s presence at all commitment hearings;
4) a finding by an impartial tribunal based on clear and convincing evidence that the child required institutional treatment;
5) a probable-cause determination within 72 hours after admission to a hospital;
6) a full hearing, including the right to confront and cross-examine witnesses, within two weeks from the date of the initial admission. App. 1097a-1098a.7
Appellants, all of the defendants before the District Court, appealed the judgment. We noted probable jurisdiction, and *646consolidated the case with Parham v. J. R., ante, p. 584. 437 U. S. 902.
II
(a) Much of what we .said in Parham v. J. R. applies with equal force to this case. The liberty rights and interests of the appellee children, the prerogatives, responsibilities, and interests of the parents, and the obligations and interests of the State are the same. Our holding as to what process is due in Parham controls here, particularly:
“We conclude .that the risk of error inherent in the parental decision to have a child institutionalized for mental health care is sufficiently great that some kind of inquiry should be made by a ‘neutral factfinder’ to determine whether the statutory requirements for admission are satisfied. . . . That inquiry must carefully probe the child’s background using all available sources, including, but not limited to, parents, schools, and other social agencies. Of course, the review must also include an interview with the child. It is necessary that the decision-maker have the authority to refuse to admit any child who does not satisfy the medical standards for admission. Finally, it is necessary that the child’s continuing need for commitment be reviewed periodically by a similarly independent procedure.” Parham v. J. R., ante, at 606-607.
The only issue is whether Pennsylvania’s procedures for the voluntary commitment of children comply with these requirements.
(b) Unlike in Parham v. J. R., where the statute being challenged was general and thus the procedures for admission were evaluated hospital by hospital, the statute and regulations in Pennsylvania are specific. Our focus here is on the codified procedures declared unconstitutional by the District Court.
The Mental Health Procedures Act of 1976 and regulations promulgated by the Secretary describe the procedures for the *647voluntary admission for inpatient treatment of mentally ill children. Section 201 of the Act provides that “a parent, guardian, or person standing in loco parentis to a child less than 14 years of age” may apply for a voluntary examination and treatment for the child. After the child receives an examination and is provided with temporary treatment, the hospital must formulate “an individualized treatment plan ... by a treatment team.” Within 72 hours the treatment team is required to determine whether inpatient treatment is “necessary” and why. Pa. Stat. Ann., Tit. 50, § 7205 (Purdon Supp. 1978). The hospital must inform the child and his parents both of the necessity for institutional treatment and of the nature of the proposed treatment. Ibid.
Regulations promulgated under the 1976 Act provide that each child shall be' re-examined and his or her treatment plan reviewed not less than once every 30 days. See § 7100.108 (a), 8 Pa. Bull. 2436 (1978). The regulations also permit a child to object to the treatment plan and thereby obtain a review by a mental health professional independent of the treatment team. The findings of this person are reported directly to the director of the hospital who has the power and the obligation to release any child who no longer needs institutional treatment.
The statute indeed provides three methods for release of a child under the age of 14 from a mental hospital. First, the child’s parents or guardian may effect his release at will. Pa. Stat. Ann., Tit. 50, § 7206 (b) (Purdon Supp. 1978). Second, “any responsible party” may petition the juvenile court if the person believes that treatment in a less restrictive setting would be in the best interests of the child. Ibid. If such a petition is filed, an attorney is appointed to represent the child’s interests and a hearing is held within 10 days to determine “what inpatient treatment, if any, is in the minor’s best interest.” Ibid. Finally, the director of the hospital may release any child whenever institutional treatment is no longer medically indicated. § 7206 (c).
*648The Mental Health and Mental Retardation Act of 1966 regulates the voluntary admission for inpatient hospital habilitation of the mentally retarded. The admission process has been expanded significantly by regulations promulgated in 1973 by Pennsylvania’s Secretary of Public Welfare. 3 Pa. Bull. 1840 (1973). Unlike the procedure for the mentally ill, a hospital is not permitted to admit a mentally retarded child based solely on the application of a parent or guardian. All children must be referred by a physician and each referral must be accompanied by a medical or psychological evalution. In addition, the director of the institution must make an independent examination of each child, and if he disagrees with the recommendation of the referring physician as to whether hospital care is “required,” the child must be discharged. Mentally retarded children or anyone acting on their behalf may petition for a writ of habeas corpus to challenge the sufficiency or legality of the “proceedings leading to commitment.” Pa. Stat. Ann., Tit. 50, § 4426 (Purdon 1969).
Any child older than 13 who is admitted to a hospital must have his rights explained to him and must be informed that a status report on his condition will be provided periodically. The older child is also permitted to object, either orally or in writing, to his hospitalization. After such objection, the director of the facility, if he feels that hospitalization is still necessary, must institute an involuntary commitment proceeding under § 406 of the Act, Pa. Stat. Ann., Tit. 50, §4406 (Purdon 1969).
What the statute and regulations do not make clear is how the hospital staff decides that inpatient care is required for a child. The director of Haverford State Hospital for the mentally ill was the sole witness called by either side to testify about the decisionmaking process at a state hospital. She described the process as follows:
“[T]here is an initial examination made by the psychiatrist, and is so designated as an admission note on the *649hospital record. Subsequently, for all adolescents on the Adolescent Service at Haverford State Hospital, there are routine studies done, such as an electroencephalogram, a neurological examination, a medical examination, and a complete battery of psychological tests and school evaluation, as well as a psychiatric evaluation. When all their data has been compiled, an entire staff conference is held, which is called a new case conference, at which point the complete case is re-examined and it is decided whether or not the child needs hospitalization, and at that same time, as well, an adequate treatment course is planned.” App. 112a.
In addition to the physical and mental examinations that are conducted for each child within the institutions, the staff compiles a substantial “pre-admission background information” file on each child.8 After the child is admitted, there is a periodic review of the child’s condition by the staff. His status is reviewed by a different social worker at least every 30 days. Since the State .places a great deal of emphasis on family therapy, the parents or guardians are met with weekly to discuss the child’s case. Id., at 113a.
We are satisfied that these procedures comport with the due process requirements set out earlier. No child is admitted without at least one and often more psychiatric examinations by an independent team of mental health professionals whose *650sole concern under the statute is whether the child needs and can benefit from institutional care. The treatment team not only interviews the child and parents but also compiles a full background history from all available sources. If the treatment team concludes that institutional care is not in the child’s best interest, it must refuse the child’s admission. Finally, every child’s condition is reviewed at least every 30 days. This program meets the criteria of our holding in Parham.9 Accordingly, the judgment of the District Court that Pennsylvania’s statutes and regulations are unconstitutional is reversed, and the case is remanded for further proceedings consistent with this opinion.
Reversed and remanded.
For the reasons stated in his opinion concurring in the judgment in Parham v. J. R., ante, p. 621, Mr. Justice Stewart concurs in the judgment.
