Summary

Discovery Charter is a public charter middle school serving 369 students in grades 5-8 in Tracy, California, operating within the Discovery Charter District and earning a consistent 3-star rating.

The school presents a mixed academic picture: it performs slightly above the state average in English Language Arts but faces significant challenges in mathematics and science, where proficiency lags behind both the state and most nearby schools like Andrew N. Christensen Middle and Jefferson. A notable strength is student engagement, with a chronic absenteeism rate of 11.3% that is nearly half the state average and better than many local schools, including Earle E. Williams Middle and Monte Vista Middle. The school spends a moderate amount per student compared to others in the area.

Discovery Charter serves a student population with a lower rate of economic need than some neighboring schools in the Tracy Joint Unified district. However, the analysis shows pronounced performance gaps among different student groups, with achievement levels varying considerably from year to year for some. The school also shows a pattern of declining test scores in the higher grades. Compared to other charters, it sits in the middle of a wide performance spectrum, far outperforming the struggling Team Charter Academy but not reaching the heights of the exceptional Jefferson, highlighting that charter school quality can vary significantly even within the same region.
