The circumstances in which a parental exception waiver may be granted under Section 310 are as follows:
(a) Children who already know English: the child already possesses good English language skills, as measured by standardized tests of English vocabulary comprehension, reading, and writing,
in which the child scores at or above the state average for his or her grade level or at or above the 5th grade average, whichever is lower; or
(b) Older children: the child is age 10 years or older, and it is the informed belief of the school principal and educational staff that an alternate course of educational study would be better suited to the childs rapid acquisition of basic English language skills; or
(c) Children with special needs: the child already has been placed for a period of not less than thirty days during that school year in an English language classroom and it is subsequently the informed belief of the school principal and educational staff that the child has such special physical, emotional, psychological, or educational needs that an alternate course of educational study would be better suited to the childs
overall educational development. A written description of these special needs must be provided and any such decision is to be made subject to the examination and approval of the local school superintendent, under guidelines established by and subject to the review of the local Board of Education and ultimately the State Board of Education. The existence of such special needs shall not compel issuance of a waiver, and the parents shall be fully informed of their right to refuse to agree to a waiver.
