(a) Doubt as to child’s competency (§§ 601, 602, 709
(1) If the court finds that there is substantial evidence regarding a child who is the subject of a petition filed under section 601 or 602 that raises a doubt as to the child’s competency as defined in section 709, the court must suspend the proceedings and conduct a hearing regarding the child’s competency.
(2) Unless the parties have stipulated to a finding of incompetency the court must appoint an expert to evaluate the child and determine whether the child suffers from a mental illness, mental disorder, developmental disability, developmental immaturity, or other condition affecting competency and, if so, whether the child is incompetent as defined in section 709(a)(2).
(3) Following the hearing on competency, the court must proceed as directed in section 709.

(A) Licensed psychiatrist who has successfully completed four years of medical school and either four years of general psychiatry residency, including one year of internship and two years of child and adolescent fellowship training, or three years of general psychiatry residency, including one year of internship and one year of residency that focus on children and adolescents and one year of child and adolescent fellowship training; or

(c) Interview of child
The expert must attempt to interview the child face-to-face.

(3) Psychosocial factors such as abuse, neglect, or drug exposure;

(5) Mental health services received during childhood and adolescence;
(6) School performance, including an Individualized Education Plan, testing, achievement scores, and retention;
(7) Acculturation issues;

(9) Medical history including significant diagnoses, hospitalizations, or head trauma.
(g) Written report
(1) Any court-appointed expert must examine the child and advise the court on the child’s competency to stand trial. The expert’s report must be submitted to the court, to the counsel for the child, to the probation department, and to the prosecution. The report must include the following:

(iv) All diagnostic and psychological tests administered, if any.
(D) A summary of the developmental history of the child as required by this rule.
(E) A summary of the evaluation conducted by the expert on the child, including the current diagnosis or diagnoses that meet criteria under the most recent version of the Diagnostic and Statistical Manual of Mental Disorders, when applicable, and a summary of the child’s mental or developmental status.
(F) A detailed analysis of the competence of the child to stand trial under section 709, including the child’s ability or inability to understand the nature of the proceedings or assist counsel in the conduct of a defense in a rational manner as a result of a mental or developmental impairment.
(G) An analysis of whether and how the child’s mental or developmental status is related to any deficits in abilities related to competency.
(H) If the child has significant deficits in abilities related to competency, an opinion with explanation as to whether treatment is needed to restore or attain competency, the nature of that treatment, its availability, and whether restoration is likely to be accomplished within the statutory time limit.
(I) A recommendation, as appropriate, for a placement or type of placement, services, and treatment that would be most appropriate for the child to attain or restore competence. The recommendation must be guided by the principle of section 709 that services must be provided in the least restrictive environment consistent with public safety.
(J) If the expert is of the opinion that a referral to a psychiatrist is appropriate, the expert must inform the court of this opinion and recommend that a psychiatrist examine the child.
(2) Statements made to the appointed expert during the child’s competency evaluation and statements made by the child to mental health professionals during the remediation proceedings, and any fruits of these statements, must not be used in any other hearing against the child in either juvenile or adult court.

Plain-English Summary

Where substantial evidence raises a doubt about the competency of a child facing a section 601 or 602 petition, the court must suspend the proceedings and hold a competency hearing. Unless the parties stipulate to a finding of incompetency, an expert is appointed to evaluate whether the child has a mental illness, mental disorder, developmental disability, developmental immaturity or other condition affecting competency, and if so whether the child is incompetent as the statute defines it.

The qualifications mirror the previous rule — a licensed psychiatrist with the stated training, or a doctorate-holding licensed psychologist — and add a requirement that the expert be familiar with the competency remediation services actually available to this child. Clinicians with other qualifications may still serve as consultants or witnesses.

Four duties then attach to the evaluation. The expert must attempt a face-to-face interview, and where the child refuses, must still try to observe and make direct contact to gather clinical observations. The expert must review all the records the statute requires, and the county’s written protocol must say who obtains those records and how. The expert must consult the child’s counsel, asking at minimum why counsel doubts competency, what counsel has observed of the child’s behaviour, and how the child interacts with counsel — and no attorney-client privilege is waived by counsel relaying what the child said.

The expert must also gather and document a developmental history: pregnancy complications or drug use, when the child talked, walked and read, psychosocial factors such as abuse, neglect or drug exposure, adverse childhood experiences including early disruption of the parent-child relationship, mental health services received, school performance including any Individualized Education Plan and testing, acculturation issues, biological and neurological factors such as head trauma, and medical history.

The report goes to the court, the child’s counsel, the probation department and the prosecution, and the rule prescribes its contents: the referring court and purpose, the expert’s own training, the procedure used — every source considered, every source sought but not obtained and why, a detailed account of attempts to meet the child and any accommodations made, and any tests administered. Then the developmental history, a summary of the evaluation with current diagnoses where applicable, a detailed analysis of competence, an analysis linking the child’s mental or developmental status to any deficits, and — where deficits are significant — an opinion on whether treatment could restore or attain competency, what that treatment is, whether it is available, and whether it is likely to work within the statutory time limit. Any placement or service recommendation must follow the statute’s principle of the least restrictive environment consistent with public safety.

One protection runs through all of it: what the child says to the appointed expert, and to mental health professionals during remediation, cannot be used against the child in any other hearing in juvenile or adult court — and neither can anything derived from those statements.

Frequently Asked Questions

Must an expert always be appointed?

No. The court must appoint an expert unless the parties have stipulated to a finding of incompetency.

What if the child refuses to be interviewed?

The expert must still try to observe and make direct contact with the child, to gain clinical observations that may inform the opinion on competency.

Does talking to the expert waive the attorney-client privilege?

No. No waiver is deemed to occur from counsel reporting the child’s statements to the expert, and those statements carry the rule’s use protection.

Can the child’s statements be used against them later?

No. Statements made to the appointed expert during the competency evaluation, and to mental health professionals during remediation — and any fruits of those statements — must not be used in any other hearing against the child in juvenile or adult court.

What must the expert’s report cover?

The referring court and purpose, the expert’s training, the sources used and those sought but unavailable, attempts to meet the child, any testing, the developmental history, the evaluation and diagnoses, a detailed competence analysis, and where deficits are significant, whether treatment could restore competency within the statutory time limit.
