Summary

Horizons School: Independent Study is a K-12 alternative public school in Pleasant Hill, CA, serving 182 students within the Mt. Diablo Unified district with a focus on non-traditional, flexible learning.

The school presents a mixed academic picture, with test scores in math and science recently matching or slightly exceeding the district average, though English scores are a bit lower. A notable feature is the small class size, with about 10 students per teacher, allowing for more individualized attention. However, families should be aware of significant year-to-year swings in graduation rates and a persistently high rate of chronic absenteeism, which is more than double the state average. Performance also varies dramatically between grade levels, with some grades excelling far above averages while others fall well below, indicating inconsistent experiences across the student body.

Compared to other alternative schools in the region, Horizons occupies a unique middle ground. It serves a more economically diverse population than some high-need alternatives and achieves moderate academic results with remarkably low per-student spending—far less than schools like Venture (Alternative) or Prospects High (Alternative). This creates an interesting paradox where outcomes aren't strictly tied to funding levels. Like many independent study programs, including Independent Study Sojourner Truth, challenges with consistent attendance and graduation gaps compared to traditional schools are common across the model.
