(a) A description of the nature, type, and extent of the respondent's specific cognitive and functional limitations, if any;
(b) An evaluation of the respondent's mental and physical condition and, if appropriate, educational potential, adaptive behavior, and social skills;
(c) A prognosis for improvement and a recommendation as to the appropriate treatment or habilitation plan; and
(d) The date of any assessment or examination upon which the report is based.
