Summary:
The Riverdale Joint Unified school district operates two high schools, Riverdale High and Horizon High, which serve grades 9-12 and share a campus but have dramatically different profiles.
Riverdale High is the district's main high school, serving nearly 500 students with exceptional graduation (97.5%) and very low dropout rates that far exceed state averages, despite academic proficiency in math and science being below state benchmarks. In stark contrast, Horizon High is an extremely small alternative program with only 7 students, a very high chronic absenteeism rate of 61.1%, and a much lower student-to-teacher ratio, suggesting it serves a specialized population with different needs.
For families, the key takeaway is that the district's primary high school successfully supports nearly all students to graduate, a significant strength, but there is a notable gap in mathematics achievement that the school is working to address. The smaller Horizon program operates with intensive resources for a handful of students. Overall, the Riverdale Joint Unified district outperforms the state in keeping students in school and graduating them, which is a positive indicator of student support and engagement.
