Due to a surplus in the State General Fund, California's Pre-K-12 teachers and administrators have an additional $490 million to spend on programs supporting professional development. The $490 million represents one of the largest investments in professional development and teacher effectiveness ever made by California and has the potential to improve every classroom in the state. Developing a system of professional learning requires contributions from all key decision makers involved in aligning people, time, and resources needed for the continuous improvement of school systems. Divided into three sections, this guidance document has been crafted with a particular eye towards bridging professional learning with approaches for implementing the state academic standards, Next Generation Science Standards (NGSS), and imminent Science and History/Social Studies frameworks. It covers: (1) Strategies for supporting professional learning; (2) Key professional learning resources for districts; and (3) Developing LCAPs (Local Control Accountability Plans) aligned with district professional learning strategies. Three appendices describe effective elements of professional learning, district examples of effective professional learning for principals, and an overview of California's Quality Professional Learning Standards with example of district application.
