As the world continues to rely more and more on technology, everyone will require a greater level of STEM literacy and fluency to understand how science and technology play a role. Greater STEM literacy also helps prepare students to better understand challenges and issues that affect them and their communities. Hands-on STEM learning opportunities help students develop an interest and comfort with STEM subjects, and understand the career pathways to pursue STEM interests. These STEM learning opportunities can take place in school and across different informal environments, but over the last decade, afterschool programs have become a cornerstone in providing STEM learning for students from all backgrounds in all regions of the country. "STEM Learning in Afterschool on the Rise, But Barriers and Inequities Exist," is based on new data collected in 2020, and provides important new insights about STEM learning in afterschool, a first-ever look at trends in afterschool STEM learning, areas for further exploration, and recommendations to help ensure that all young people have access to high quality afterschool STEM opportunities.
