Today's high-quality curricula are focused on inquiry and making meaning from real-world phenomena and experiences. Many teachers didn't learn in this way when they were students or when they were teachers in training, so they need and deserve opportunities to dive into the curriculum and become experts at applying it. The implementation of this kind of professional learning is a complex and challenging undertaking (Chu et al., 2022). It requires putting into practice all the components known to make professional learning high quality, which are outlined in the Standards for Professional Learning (Learning Forward, 2022). Curriculum-based professional learning should be job-embedded, relevant and responsive to classrooms and instructional practices, and sustained, with multifaceted and appropriate learning designs. Learning Forward, with grant funding from the Carnegie Corporation of New York, developed the Curriculum-Based Professional Learning Network to help educators engage in this kind of high-quality curriculum-focused learning and implement curricula with integrity so that student learning improves.
