Continuous improvement is a holistic and research-based approach to education grounded in the belief that every system is designed to achieve the results it gets; therefore, change must be systemwide, not piecemeal. California is a national leader in the continuous improvement movement that is spreading throughout local school districts as well as state and county offices of education. At its annual conference in February 2019, PACE convened a panel of California educators working on the cutting edge of continuous improvement. In this brief, they share their stories and lessons learned.
