Continuous improvement methods, widely used in fields such as medicine, can help educators identify and try out adjustments in practice, known as "change ideas," which contribute to better outcomes and more equitable systems for students. Since 2018, the Bill & Melinda Gates Foundation has invested in 24 organizations across the United States to support networks of schools to use continuous improvement methods to advance equity in education -- with the specific aim to increase the number of Black and Latino students and students experiencing poverty who earn a high school diploma, enroll in college, and are on track for college success. This article discusses how the Networks for School Improvement support educators to use data to adapt research- and evidence-based practices to their specific contexts through cycles of continuous inquiry.
