The California Mathematics, Science, and Computer Science Partnership (CAL-MSCS) is a state-funded initiative designed to strengthen connected systems of professional learning across mathematics, science, and computer science. Guided by four grant goals, CAL-MSCS works to: (1) build and expand professional learning systems,(2) develop and disseminate high-quality professional learning opportunities, (3) enhance family and community engagement, and (4) build coherence across related professional learning initiatives statewide.

CAL-MSCS represents the first state-funded grant dedicated to science professional learning, establishing a powerful foundation for connection and collaboration across California. Recent findings shared by the WestEd evaluation team with the statewide science leadership team highlight how this connected system took shape during the 2024–25 school year:

• 48 out of 58 counties participated in the two statewide Science Community of Practice in-person convenings in the 24/25 school year, strengthening cross-county relationships and shared leadership.
• County offices of education are consistently facilitating local teacher leader networks and communities of practice, creating sustained, place-based systems of support for science educators.
• Counties are expanding connections beyond classrooms by engaging students and families through Science Fairs and STEM/STEAM events that center hands-on, community-based science learning.
• Many counties are leveraging CAL-MSCS to promote multidisciplinary learning, intentionally integrating science professional learning with mathematics and/or computer science.
• CAL-MSCS has provided 120.5 hours of statewide professional learning opportunities in science. Additionally, over 2,000 hours of professional learning opportunities in science have been reported by the local implementation teams within California - demonstrating alignment between statewide vision and local action.

As we reflect on the first full year of implementation, these stories illustrate how connected systems, shared leadership, and coherent professional learning are driving meaningful success in science education. CAL-MSCS is looking forward to many more opportunities in the 25/26 school year to amplify our support of educators and students across California!
