Each local and regional board of education shall limit the time an eligible student spends in a program of bilingual education to thirty months, whether or not such months are consecutive, except that summer school and two-way language programs pursuant to subsection (i) of this section shall not be counted. If an eligible student does not meet the English mastery standard at the end of thirty months, the local or regional board of education shall provide language transition support services to such student. Such services may include, but need not be limited to, English as a second language programs, sheltered English programs, English immersion programs, tutoring and homework assistance.
