Summary

Delta High is a small public high school serving grades 10-12 in Clarksburg, California, with about 196 students in the River Delta Joint Unified district, which ranks in the lower third of districts statewide.

This school presents a notable paradox: while it graduates nearly all its students (98.5%) and has virtually no dropouts—outcomes better than the state average—its academic proficiency scores, especially in math (under 10%), are significantly low and have declined sharply over the past decade. The school serves a community with high economic need, with 75% of students qualifying for free or reduced-price lunch. Compared to nearby schools like Franklin High or the School of Engineering & Sciences, which serve students with similar challenges, Delta High's academic performance is lower despite having a favorable student-teacher ratio and improving attendance rates.

The small size of Delta High appears to foster strong support systems that keep students engaged and on track to graduate, but serious questions remain about the quality of academic instruction. Parents should consider that the school excels at helping students finish high school but struggles to prepare them to meet state standards in core subjects, a pattern that differs from other area schools facing similar demographic challenges.
