Are we truly growing our teachers, or just ticking boxes? In this first Voice of TIE podcast fo the school year, the Director of TIE, Stacy Stephens sits down with two colleagues from the Principals' Training Center, Scott Jackson, Head of Campus at the International School of Stuttgart, and Leanne Dominguez, Deputy Head of School in Kazakhstan, to tackle one of the most consequential yet under examined systems in international education: instructional supervision.
Fresh off a summer of training school leaders from around the world, the three unpack why so many appraisal systems default to compliance over growth. They explore the tension between accountability and development, the danger of treating frameworks as endpoints rather than starting points, and why the best growth systems become almost invisible and are replaced by rich, ongoing conversations about teaching and learning.
From the power of teacher-driven evidence to the critical distinction between commitment and compliance, this episode challenges leaders to stop winging it and start building coherent, differentiated systems that genuinely develop teachers. Whether you're heading back to campus or mid-year, this is the conversation you need before your next observation cycle begins.
