Summary:

The Gridley Unified school district in California consists of five schools serving grades K-12, with a total enrollment around 2,000 students in a predominantly high-need community.

Among these schools, Gridley High stands out as a top performer, ranking in the 84th percentile of all California high schools with an exceptional 94.5% graduation rate and strong scores in English Language Arts. In contrast, the elementary and middle schools—Wilson Elementary, McKinley Elementary, and Sycamore Middle—perform closer to or below state averages, showing a notable performance gap before high school.

The district faces significant challenges, particularly in mathematics where proficiency lags behind the state average, and at Esperanza High (Continuation), which has severe attendance issues and the lowest academic outcomes despite much higher per-student spending. Chronic absenteeism is a concern district-wide and is strongly correlated with lower academic performance.
