With the goal of improving student learning, TPI-US reviews teacher preparation programs to determine how the programs can expand their promising practices and address areas of improvement. TPI-US envisions a system of teacher preparation where every level of leadership takes relentless ownership of their graduates' effectiveness in the classroom and continuously evaluates their practices to ensure new teachers—and their students—are well prepared to thrive on day one.

TPI-US has recruited, selected, and trained a cadre of team and lead inspectors with professional education experience in a variety of areas including as current or former P-12 principals, reading specialists, turnaround specialists, teachers, district content area specialists, teacher educators and other educational professionals. They all have demonstrated their commitment to improving the quality of teaching and learning in the United States, sharing with TPI-US the fundamental belief that the chief purpose of teacher preparation is to recruit, prepare, and support teachers whose effectiveness is measured by their positive impact on student learning outcomes.
