Teachers and teacher aides who are not bilingual-crosscultural teachers and aides, as defined by subdivisions (h) and (i) of Section 52163, shall not be permitted to teach in programs authorized pursuant to subdivision (a), (b), or, unless waived by the board, (c) of Section 52163, except as provided in Sections 52166 and 52178, or except as staffing requirements are waived by the board pursuant to subparagraph (B) of paragraph (1) of subdivision (c) of Section 52163. It is the intent of the Legislature that the provisions of Section 44955 shall apply to this section. However, in no case shall a school district dismiss a fully certificated teacher, who previously taught in the bilingual-bicultural program pursuant to a waiver granted under Section 52178, solely on the basis that such waiver has expired. Even if such person is unable to qualify for a bilingual credential or a bilingual-crosscultural certificate of competence, he or she shall retain his or her status, seniority, and rights as a probationary or permanent employee, as the case may be, for the purpose of serving as a monolingual teacher in other programs offered by the school district.
