The Multiple Subject Teaching Credential authorizes its holder to teach in a self-contained classroom in which several subjects are taught by the same teacher to the same group of students. Most elementary schools are organized around self-contained classrooms. The Multiple Subject Teaching Credential is also an authorization to teach in middle school core programs and, with relevant supplementary authorizations, in subject oriented departments: e.g., math or science. In addition to standard foundations, methods and field-based practicum courses, preparation for this credential includes the study of language acquisition, culture, bilingual education, and instructional strategies for second language learners.
