Summary:

The Chaffey Joint Union High district consists of 11 schools serving grades 9-12 in the region, ranking in the top 25% statewide and showing particular strength in English Language Arts and graduation rates.

Among the standout schools, Etiwanda High and Los Osos High are the highest performers, both earning 5-star ratings with strong graduation rates and academic proficiency, while Rancho Cucamonga High also shows consistent excellence. The district includes specialized options like the successful Chaffey District Online High and alternative schools such as Valley View High (Continuation) and Chaffey Community Day that serve students with specific needs.

Key challenges for the district include a chronic absenteeism rate significantly higher than the state average and math proficiency that lags behind the state, with only Los Osos and the online school exceeding the state average. There is notable variation in per-student spending, with higher spending often associated with schools serving more challenging student populations rather than directly correlating with higher test scores.
