The director may establish agreements with the Department of Vocational Rehabilitation for the operation of reception and evaluation centers. The reception and evaluation centers shall make a complete study of each committed youthful offender, including a mental and physical examination, to ascertain his personal traits, his capabilities, pertinent circumstances of his school, family life, any previous delinquency or criminal experience, and any mental or physical defect or other factor contributing to his delinquency. In the absence of exceptional circumstances, such study shall be completed within a period of thirty days. The reception and evaluation center shall forward to the director and to the division a report of its findings with respect to the youthful offender and its recommendations as to his treatment. At least one member of the division shall, as soon as practicable after commitment, interview the youthful offender, review all reports concerning him and make such recommendations to the director and to the division as may be indicated.
