School districts shall provide for the maximum practical involvement of parents of children in transitional bilingual education programs. Each school district shall, accordingly, establish a parent advisory committee which affords parents the opportunity effectively to express their views and which ensures that such programs are planned, operated, and evaluated with the involvement of, and in consultation with, parents of children served by the programs. Such committees shall be composed of parents of children enrolled in transitional bilingual education programs, transitional bilingual education teachers, counselors, and representatives from community groups; provided, however, that a majority of each committee shall be parents of children enrolled in the transitional bilingual education program. Once established, these committees shall autonomously carry out their affairs, including the election of officers and the establishment of internal rules, guidelines, and procedures.
