(a) Exception to FAPE for certain students. Except as provided in Sec. 300.122(a)(2)(ii), the obligation to make FAPE available to all children with disabilities does not apply with respect to students aged 18 through 21 to the extent that State law does not require that special education and related services under Part B of the Act be provided to students with disabilities who, in the last educational placement prior to their incarceration in an adult correctional facility--

(1) Were not actually identified as being a child with a disability under Sec. 300.7; and
(2) Did not have an IEP under Part B of the Act.

(b) Requirements that do not apply. The following requirements do not apply to students with disabilities who are convicted as adults under State law and incarcerated in adult prisons:

(1) The requirements contained in Sec. 300.138 and Sec. 300.347(a)(5)(i) (relating to participation of children with disabilities in general assessments).
(2) The requirements in Sec. 300.347(b) (relating to transition planning and transition services), with respect to the students whose eligibility under Part B of the Act will end, because of their age, before they will be eligible to be released from prison based on consideration of their sentence and eligibility for early release.

(c) Modifications of IEP or placement.

(1) Subject to paragraph (c)(2) of this section, the IEP team of a student with a disability, who is convicted as an adult under State law and incarcerated in an adult prison, may modify the student's IEP or placement if the State has demonstrated a bona fide security or compelling penological interest that cannot otherwise be accommodated.

(2) The requirements of Secs. 300.340(a) and 300.347(a) relating to IEPs, and 300.550(b) relating to LRE, do not apply with respect to the modifications described in paragraph (c)(1) of this section.
