Return Reference	Explanation
Form 990, Part III, Line 2: New Services	In 2019, together with a researcher at the Pennsylvania State University, NCSE conducted a rigorous national survey of science teachers in public middle and high schools. The survey partly replicated a 2007 survey of biology teachers in public high schools about their teaching of evolution and partly replicated a previous NCSE/Penn State 2014-2015 survey of science teachers in public middle and high schools about their teaching of climate change. The results will be published in the peer-reviewed literature starting in 2020, and will also help to inform NCSE's efforts in defending and promoting the teaching of these socially - though not scientifically - controversial areas of science.
Form 990, Part III, Line 4d: Other Program Services Description	OTHER PROGRAM SERVICES 4: Communications: NCSE is the go-to source for the public generally, and the news media in particular, for up-to-date information on threats to the integrity of the science classroom.

In conjunction with the website launch, we changed our domain from .com to .ngo to ensure that visitors understand our non-profit status. We continued to send our monthly e-newsletter, which had a subscriber list of about 25,000 in 2019. We also send a quarterly print publication to our members, Reports of the National Center for Science Education.
