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. The National Association of State Directors of Teacher Education and Certification (NASDTEC) facilitates license reciprocity for member states that have signed the NASDTEC Interstate Agreement. The NASDTEC Interstate Agreement is a collection of individual agreements by member states pledging to "issue some form of authorization allowing an inbound certificate holder to legally teach or provide service in the receiving state, provided the license issued by the 'sending' state is acceptable under the agreement." NASDTEC does not guarantee "full teacher license reciprocity" for member states but does help clarify which licenses will transfer and what additional requirements must be met. Forty-seven states and the District of Columbia have signed the NASDTEC Interstate Agreement. This document lists each state, whether the state has signed the NASDTEC Interstate Agreement, and the source where this information is documented (when applicable).
