This policy brief and fact sheet from the Learning Policy Institute outline Texas’s substantial investment in teacher residencies, a research-based, practice-oriented approach to teacher preparation. Following legislative direction, the Texas Education Agency (TEA) launched a large-scale residency expansion to improve access to high-quality training and address teacher workforce shortages. The research in this brief demonstrates how this investment has enhanced candidate competence, instructional preparedness, teacher preparation programs, and district hiring practices. Key design decisions made by the TEA played a critical role in driving these successes. The brief offers strategic recommendations for funding mentor and resident stipends and providing technical assistance to sustain the progress of this teacher workforce initiative. This brief is valuable for teacher preparation faculty, policymakers, and administrators focused on improving teacher preparation and addressing workforce challenges.
