Summary

Castle Rock is a public K-12 alternative school serving 315 students in Crescent City, CA, as part of the Del Norte County Office of Education, and it stands out for its exceptional success in helping students graduate and attend school regularly, even though its test scores are below state averages.

The school's greatest strengths are its high graduation rate of 84.9% and its very low dropout and chronic absenteeism rates, both of which are significantly better than the district and state averages. This is particularly notable when compared to another local alternative school, Del Norte Community, which has a much lower graduation rate and a severe absenteeism problem, despite spending nearly $10,000 more per student. Castle Rock achieves these strong engagement outcomes while serving a student population with high economic need.

While Castle Rock's test scores in English, math, and science are below the state average, they are slightly above the district's average, and the school has shown steady improvement in graduation rates over recent years. For comparison, Uncharted Shores Academy, a nearby K-9 school in the Uncharted Shores Academy District, has higher academic proficiency. This suggests Castle Rock's alternative model is highly effective at supporting students to stay in school and graduate, with room to grow in translating that daily engagement into higher academic achievement.
