Teacher credential reciprocity failures force relocating teachers to repeat coursework and testing, creating 6-18 month gaps in employment

A fully licensed, experienced teacher who moves from one U.S. state to another frequently cannot begin teaching immediately because their credential is not recognized by the new state. Despite the existence of interstate compacts (like the NASDTEC Interstate Agreement), states impose additional requirements — extra exams (Praxis vs. state-specific tests), additional coursework (state history, state-specific pedagogy courses), background check reprocessing, and transcript re-evaluation — that take 6-18 months and $1,000-$5,000 to complete. So what? A teacher with 10 years of experience in Texas who moves to California for a spouse's job must take the CBEST, CSET, and complete a California-specific course on the U.S. Constitution, even though they hold a valid Texas certification and have a decade of demonstrated competence. So what? During the 6-18 month gap, the teacher either works as a substitute (at 40-60% of regular pay with no benefits) or leaves education entirely, and their former classroom is filled by another substitute or remains vacant. So what? This is not a niche problem: approximately 200,000-300,000 teachers relocate across state lines each year (military spouses alone account for 35,000+), and the friction directly contributes to the national teacher shortage of 55,000+ unfilled positions. So what? Schools in states with the most restrictive reciprocity rules (California, New York, Illinois) have the hardest time filling positions despite having the largest applicant pools from other states. So what? Students in hard-to-staff schools (rural, high-poverty, special education) bear the brunt because those are the positions most likely to be filled by relocating teachers — who are now blocked by bureaucratic barriers unrelated to teaching ability. It persists because teacher licensing is governed by each state's department of education independently, with no federal authority to mandate reciprocity, and each state's licensing board has financial and institutional incentives to maintain its own testing and coursework requirements.
