This Noyce Track 4 project aims to serve the national need of improving STEM teacher retention and effectiveness in high-need school districts (HNSDs) by fostering a collaborative Community of Practice (CoP) among multiple institutions. The initiative addresses persistent challenges in recruiting, preparing, and retaining secondary STEM teachers in HNSDs by leveraging a network of teacher preparation programs across the United States. Through a combination of data-driven research and community engagement, this project will systematically study factors influencing teacher persistence and effectiveness while developing strategies to enhance STEM teacher preparation. The project includes large-scale data collection, quantitative and qualitative analysis of teacher experiences, and dissemination of findings to refine teacher education practices. By promoting collaboration and knowledge sharing, the project has the potential to improve STEM education for all students and strengthen the STEM teacher workforce. This project at a consortium of universities, including Alabama A&M University, Central Washington University, Middle Tennessee State University, North Dakota State University, University of Colorado Colorado Springs, University of Houston, University of Nevada-Reno, University of Texas at Austin, and University of Texas Rio Grande Valley, is designed to investigate and enhance STEM teacher persistence and effectiveness in HNSDs. Key project goals include analyzing the imp
