Tens of thousands of teachers step into classrooms each year without the training needed to help students learn to read. NCTQ’s Teacher Prep Review: Strengthening Elementary Reading Instruction analyzed nearly 700 teacher preparation programs across the country, showing state leaders, policymakers, and programs themselves where teacher preparation could do better. It provided customized course-level feedback and individualized state profiles illustrating the quality of states’ prep programs and reading policies, coupled with highly personalized campaigns supporting state leaders, advocates, and programs to drive improvement. This report and resources are already yielding policy changes and galvanizing action. The Teacher Prep Review shaped the narrative on teacher prep’s critical role in reading instruction, with 645 traditional news media mentions by early July. NCTQ engaged with PIE network members, advocates, policymakers across the nation through 20 webinars held with an estimated 250+ attendees, and more than 20 individual phone calls.  The Teacher Prep Review catalyzed and informed legislative action: NY legislator announced a science of reading bill aimed at teacher prep programs; Ohio recently passed legislation holding teacher prep programs accountable after NCTQ supported local advocates’ push; and NCTQ partnered with advocates in New Mexico, Illinois, and Georgia to supply new data and analysis that yielded new literacy laws focused on teacher prep to support teachers and their students in learning to read.
