The DoS – Dimensions of Success – tool is used to guarantee quality curriculum and programming. DoS defines twelve indicators of STEM program quality in out-of-school time and it was developed and studied with funding from the National Science Foundation (NSF) by the Program in Education, Afterschool and Resiliency (PEAR), along with partners at Educational Testing Services (ETS) and Project Liftoff. Also, pre and post assessments are administered and program surveys are sent to participants to allow us to collect data and share the good work we do.
