The 50 State Afterschool Networks, an initiative of the Charles Stewart Mott Foundation

Since 2009, the Noyce Foundation and now STEM Next has made significant investments in statewide afterschool networks to develop statewide systems to support informal science in afterschool. The Noyce Foundation began to formally collaborate with the Charles Stewart Mott Foundation in 2012 to leverage their investments and
 build off the existing network infrastructure in order to expand 
the availability of quality STEM in afterschool and summer and impact more students across the country. Through this joint venture, 32 states are working to build STEM state systems. This continued investment builds a solid foundation for states to sustain the work beyond the two foundations through public and private state investments along with the incorporation of informal science within larger STEM learning efforts.
