Summary

Clifford Elementary is a K-8 school serving 698 students in the Redwood City Elementary district, representing a steadily improving choice that consistently outperforms both district and state averages in English, Math, and Science.

The school stands out for its effective support of students from diverse economic backgrounds, achieving strong academic results while showing a clear, multi-year trend of improvement in its statewide ranking. It manages student attendance better than some nearby schools with similar profiles, such as Rocketship Redwood City. As a K-8 campus, it offers the benefit of continuity through middle school, with performance in grades 7 and 8 that exceeds the district average. However, the school faces a clear challenge in ensuring all student groups perform at similarly high levels, and its middle-grade math and science scores show room for growth compared to a higher-performing neighbor like Roy Cloud Elementary.

When looking at the broader area, there is a notable performance gap between schools in Redwood City and those in the adjacent San Carlos Elementary district, which includes top-ranked schools like Brittan Acres Elementary. This suggests community and district-level factors play a significant role. Overall, Clifford Elementary is on a positive trajectory and is a solid performer within its district, with clear strengths and identified areas where focused effort could lead to even greater success for all students.
