Every person so sentenced shall be segregated for a period not to exceed thirty (30) days during which period the person shall be studied and evaluated to determine whether the person shall be a maximum, medium, or minimum security risk and to develop a program of rehabilitation, education, and medical and other care as shall be deemed necessary and appropriate to prepare the person to become a useful member of society. During the period, a medical assessment, and an assessment of rehabilitative needs shall be made of the person and the results, together with the nature of the offense for which the person has been committed, the previous criminal history, if any, the recommendations of the department of the attorney general and of the sentencing court and the social history of the person shall be studied and evaluated in determining the degree of custodial care of the person, the rehabilitation program for the person, the medical or other care that may be necessary and the spiritual and religious guidance that shall be indicated by the preference of the person.
