These downloadable assessment and planning tools – geared to OST practitioners — were developed by the California AfterSchool Network and the California STEM Learning Network but are applicable to programs and partnerships in any state. Especially useful are the clear definitions of quality for OST and OST STEM, and the detailed descriptions of what strong partnerships among schools, OST programs, and other stakeholders look like in practice. Supported by the S.D. Bechtel, Jr. Foundation, the Noyce Foundation, and the Samueli Foundation.
