Summary

Cobblestone Elementary is a well-regarded K-6 public school serving 372 students in the Rocklin Unified district, consistently earning a 4-star rating and ranking in the top 15% of California elementary schools.

The school demonstrates notable strengths in mathematics, where student proficiency significantly outpaces both district and state averages, and in maintaining an exceptionally low rate of chronic student absenteeism, which is a fraction of the state average. It operates efficiently, achieving these solid academic results with moderate per-student spending compared to some neighboring schools like Rock Creek Elementary and Ruhkala Elementary. While its overall performance is strong, it sits in the middle tier among local schools, outperforming others such as Antelope Creek Elementary but trailing top performers like Valley View Elementary and the charter school Rocklin Academy.

Cobblestone shows particular effectiveness in supporting specific student groups, with historically strong results for students in special education and those from economically disadvantaged backgrounds. The school has shown remarkable success in improving student attendance since the pandemic and maintains stable, high performance year over year. Its challenge and opportunity lie in continuing to close the achievement gap with the highest-performing schools in the area while serving its diverse student community.
