(b) No person shall be transferred pursuant to this section until and unless the person voluntarily, intelligently, and knowingly executes a written consent to the transfer, which shall be irrevocable.
(c) Prior to being returned to the Youth Authority, a person in the custody of the Department of Corrections who is scheduled to be returned to the Department of the Youth Authority shall meet personally with a Youth Authority parole agent or other appropriate Department of the Youth Authority staff member. The parole agent or staff member shall explain, using language clearly understandable to the person, all of the following matters:
1. (1) What will be expected from the person when he or she returns to a Youth Authority institution in terms of cooperative daily living conduct and participation in applicable counseling, academic, vocational, work experience, or specialized programming.
2. (2) The conditions of parole applicable to the person, and how those conditions will be monitored and enforced while the person is in the custody of the Youth Authority.
3. (3) The person’s right under this section to voluntarily and irrevocably consent to continue to be housed in an institution under the jurisdiction of the Department of Corrections instead of being returned to the Youth Authority.
(d) A person who has been returned to the Youth Authority after serving a sentence described in subdivision (a) may be transferred to the custody of the Department of Corrections if the person consents to the transfer after having been provided with the explanations described in subdivision (c).

However, the board shall not order or recommend any treatment, education, or other programming that is unavailable in the institution where the person is housed, and shall not deny parole to a person housed in the institution based solely on the person’s failure to participate in programs unavailable to the person.
(f) Any person housed in an institution under the jurisdiction of the Department of Corrections pursuant to this section who has not attained a high school diploma or its equivalent shall participate in educational or vocational programs, to the extent the appropriate programs are available.
