Since their introduction to teacher education programs in the 1980s, teacher education cohorts have become a standard scheme of organization in teacher preparation programs. This literature review notes some common characteristics and issues in cohort operations. Cohorts contain a standard academic core, class scheduling, and timeline to program completion, providing a teacher socialization aspect at entry to the profession. While holding great potential for positive influence by encouraging goal accomplishments, cohorts can create unintended effects, like unhealthy competition, exclusion, and miscommunication. Accordingly, Teacher educators should provide guidance and clear communications to pre-service teacher cohorts to minimize potential negative outcomes.
