Iowa's House File 2317, which if enacted would have reversed the state's adoption of the Next Generation Science Standards in 2005, died on February 16, 2018, when a deadline for bills to pass committee in their house of origin passed.
Connecticut's Senate Bill 345 would, if enacted, require the teaching of climate change "consistent with the Next Generation Science Standards" in the state's public schools, and would also task the state department of energy and environmental protection with helping local and regional school districts develop appropriate curricula to do so.
