““BOTH PEARSON EDUCATION AND THE NONPROFIT Center for Applied Linguistics (CAL) have promoted SIOP as an all-purpose educational product: a tool for evaluating teachers, a template for lesson planning and “delivery,” and a course of professional development. They advertise their model as ideal not only for English learners (pre-K–12 and adult), but also for mainstream and special education students in the United States, as well as language students worldwide. Clearly, they believe the market potential is vast.””
