Since 1998, more than 16,000 Tech Trekkers have attended camp, thanks to the dedication of volunteers from over 100 AAUW branches who selected, sponsored, and supported them.
AAUW California Tech Trek Alum Zone (TTAZ) Committee’s mission is to help these branches build and strengthen lasting connections with Tech Trek alums by supporting the formation and sustainability of local Tech Trek Alum Groups (TTAG) and encouraging engagement with the statewide Tech Trek Alum Community (TTAC). Our goal is to keep alums connected with like-minded young women through fun and meaningful STEM activities that support their educational and career paths—while also welcoming them into the broader AAUW community.

Program Goals
The long-term success of Tech Trek as a STEM program depends on its lasting impact on alums and protecting the investments already made by our members and donors. Strengthening existing Tech Trek Alum Group (TTAG) programs, creating new ones, and supporting broader alum initiatives (e.g., the Tech Trek Alum Community, TTAC) are top priorities for the AAUW California Tech Trek committee and the Tech Trek Alum Zone (TTAZ) workgroup.
The mission of TTAZ is to build a strong statewide network of California branches and groups with Tech Trek alum programs, enabling them to share resources and best practices. This collaboration fosters deeper engagement and lasting connections with Tech Trek alums, including potential membership and volunteer support.
To advance this mission, AAUW California Tech Trek is introducing a microfunding program to support these alum initiatives called Tech Trek Alum Program (TTAP) Microfunding.
