Summary:

The Castaic Union School District consists of four public schools serving grades K-8, with three elementary schools and one middle school, educating a total of about 1,900 students in a district that ranks in the top 25% statewide.

Among the schools, Northlake Hills Elementary stands out as the top performer with the highest test scores in both English and math, while Castaic Elementary excels in student attendance with remarkably low chronic absenteeism. Castaic Middle is a strong middle school with the district's highest ranking for its grade level. In comparison, Live Oak Elementary has lower overall proficiency rates and higher absenteeism, suggesting it may benefit from additional support.

Overall, the district performs better than California state averages in all core subjects. An interesting finding is that the highest-performing elementary school also has the highest percentage of students qualifying for free or reduced-price lunch, indicating effective teaching strategies. Parents should note a dip in fifth-grade math scores across multiple schools, which the district is likely examining. The schools generally maintain consistent, above-average ratings, making Castaic Union a solid choice for families.
