Our Impact

Results from the recent school year show outstanding student growth in both math and reading at two of our partner schools.

2023 Third Grade STAR Assessments in Reading & Math

2023 Independent evaluation of the K-3 Proficiency Project’s implementation and outcomes was conducted by WestEd, a respected leader in educational research and evaluation.


“Students from all grades at both Sonoma Charter and Sassarini Elementary
have demonstrated excellent growth and progress since Fall 2020.
The K-3 Proficiency Project shows consistent and strong promise
for having positive impacts on student reading and math outcomes.”

Looking back now, it’s easy to see why we were able to make the gains we did. I’ve never worked with such a dedicated team of coaches, teachers and support staff. What started out as a best-practices project for grades K-3 has now become the culture-defining element for the school. You can’t hope for anything better than that. Sonoma Charter remains committed to K-3 Proficiency Project practices year-after-year for one reason: it works!

Boosting achievement

The K-3 Proficiency Project model is designed to assist educators and improve student outcomes. To truly succeed, the K-3 Proficiency Project needs support and engagement from the communities we serve. We operate in partnership with the schools getting involved to support our efforts. Then, together, we all benefit – every student, teacher, parent, school, and our Sonoma County community. Please contact Ashley Tatman (atatman@k3innovation.org) if your school would like to be considered for K-3 Proficiency Project.
