This report from the American Association of Colleges for Teacher Education and the Center for American Progress discusses key findings on alternative certification programs for educators. Alternative certification programs typically provide individuals who already have a bachelor’s degree with a pathway to certification that does not require them to obtain another degree. In these programs, candidates can become a “teacher of record”—taking responsibility for leading a class and often teaching without direct supervision—before completing all their certification requirements. These programs can be run by institutions of higher education (IHEs) or by other organizations. Alternative teacher certification programs that are not operated by IHEs take various forms, which are discussed in the report, and have experienced steady growth in enrollment in the past decade. IHE-based comprehensive and alternative teacher preparation programs, on the other hand, have not experienced such growth. Alongside the growth of non-IHE alternative teacher certification programs, concerns have emerged about their efficacy. A better understanding of these programs is needed to ensure that all teachers are prepared to support every student.
