This bill requires the California Commission On Teacher Credentialing, upon recommendation by a tribal government of a federally recognized Indian tribe in California, to issue an American Indian languages credential to a candidate who has demonstrated fluency in that tribal language, and met other requirements. The bill authorizes the holder of an American Indian languages credential to teach the American Indian language for which the credential was issued in California public schools in preschool, kindergarten, grades 1 to 12, inclusive, and in adult education courses, and would make the holder of that credential eligible for a professional clear teaching credential upon completion of a specified period of time and application and consultation as specified. The bill encourages each federally recognized American Indian tribe to develop a written and oral assessment that should be successfully completed before an applicant is recommended for an American Indian languages credential.
