This module focuses on assessing whether your school's professional development investments are actually translating into better teaching and improved student outcomes. Participants will learn how to move beyond attendance and satisfaction surveys to measure real changes in teacher practice, classroom implementation, and instructional quality following PD sessions. The course covers how to set clear, measurable goals for PD initiatives from the outset, select appropriate data sources (observations, student work, performance data, teacher self-reports), and analyze whether training is being applied in classrooms over time. You'll also explore how to identify which PD formats and providers deliver the strongest return on investment, helping you make smarter decisions about where to direct your professional development budget. By the end, you'll have a practical framework for evaluating PD efforts so your school can invest in training that genuinely strengthens teaching and supports student success.
