Research shows that teachers have the biggest impact on student learning. As a result, helping teachers access high-quality professional development is top-of-mind for many network partners. However, understanding how to measure the impact and effectiveness of their PD programs is often overwhelming and difficult, and many organizations working in this space are eager for support and guidance on how to evaluate the efficacy of their programs.

In 2017, Exxon partnered with 100Kin10 to host a funding competition, aimed at catalyzing and fueling a response to this need from the network. Specifically, Exxon was interested in 100Kin10 partners' approaches to conducting environmental scan of how science PD providers are evaluating their impact, and in particular, how they are assessing their contribution toward improved teaching and longevity in the classroom. 100Kin10 partner WestEd was awarded resources to perform this scan with the goal of pointing to existing strong approaches and practices that others could adapt. The end-result of the partnership is a set of white papers with insights into the evaluative process that explain what evaluation can accomplish, how to approach evaluation, and where to turn for help:
