Teacher license reciprocity allows educators who hold a teaching license in one state to earn a license in another state, subject to meeting state-specific requirements. Reciprocity agreements allow states to work through variations in licensing systems to coordinate license transfers and fill vacant teaching positions with qualified candidates. Most states have policies in place to extend reciprocity for certain teachers, but few states provide full reciprocity for all fully licensed teachers from other states. Forty-three states and the District of Columbia require that some or all out-of-state teacher candidates take additional assessments prior to entering a classroom, or within a certain number of years of teaching. This document lists each state, whether the state requires out-of-state teachers to take additional assessments, and the source where the policy is located.
