[This is one of a dozen upcoming blog posts about our six-year involvement leading the NASA Heliophysics Science Education and Public Outreach Forum. ]

Evaluation for the NASA Science Mission Directorate Heliophysics Forum focused on the three main goals: 1) Engage and develop the education and public outreach (EPO) community,  2) Analyze heliophysics EPO products and projects, and 3) Coordinate communication about EPO work. Through multiple evaluation activities over multiple years, we found the Forum was able to support the EPO community with professional development, an online community of practice, collaborative projects, and a database of resources. Community members became more engaged over time with each other and with the forum’s activities. They asked for, and received professional development on topics such as social media, scientist engagement, misconceptions, evaluation, NGSS (Next Generation Science Standards), product review, 508 compliance (accessibility), and storytelling.  They met monthly online, and yearly face-to-face, and collaborative projects grew out of that to co-host events, develop new initiatives, and share audiences.
