EXPERT'S REPORT.

(1) identify and address specific issues referred to the expert for evaluation;

(2) document that the expert explained to the defendant the purpose of the evaluation, the persons to whom a report on the evaluation is provided, and the limits on rules of confidentiality applying to the relationship between the expert and the defendant;

(3) in specific terms, describe procedures, techniques, and tests used in the examination, the purpose of each procedure, technique, or test, and the conclusions reached; and

(4) state the expert's clinical observations, findings, and opinions on each specific issue referred to the expert by the court, state the specific criteria supporting the expert's diagnosis, and state specifically any issues on which the expert could not provide an opinion.

(1) the symptoms, exact nature, severity, and expected duration of the deficits resulting from the defendant's mental illness or intellectual disability, if any, and the impact of the identified condition on the factors listed in Article 46B.024;

(2) an estimate of the period needed to restore the defendant's competency, including whether the defendant is likely to be restored to competency in the foreseeable future; and

(3) prospective treatment options, if any, appropriate for the defendant.

(c) An expert's report may not state the expert's opinion on the defendant's sanity at the time of the alleged offense, if in the opinion of the expert the defendant is incompetent to proceed.
