Summary

Mesa Elementary is a K-8 school serving 597 students in Somis, CA, operating within the well-regarded Mesa Union Elementary district and consistently performing above state averages in English and Math.

The school has a remarkable strength in student attendance, with a chronic absenteeism rate of just 5%, which is far better than the state average and outperforms many nearby schools like Rio Del Mar (28.3%) and Citrus Glen Elementary (16.6%). Academically, it shows particular success in preparing its 8th graders, who score well above state averages, though there is a noticeable performance dip in 5th grade that the school could address. While not the top academic performer in the area compared to schools like Los Primeros School of Sciences & Arts, Mesa delivers solid results efficiently, spending less per student than several neighboring schools in lower-ranked districts.

Over the past decade, Mesa's statewide ranking has gradually declined, a trend that contrasts with some stable high-performing peers. The school achieves its outcomes with moderate class sizes and represents a strong value, offering reliable education with excellent student engagement and efficient use of resources within its community context.
