Summary:

The Placer Union High district consists of five high schools serving grades 9-12 in a California district where overall academic performance exceeds state averages.

Among the traditional high schools, Del Oro High stands out as the top performer with the strongest test scores, a near-perfect 99.5% graduation rate, and the lowest chronic absenteeism. Colfax High is notable for its perfect 100% graduation and 0% dropout rates, while Placer High has the highest per-student spending but more moderate academic results. Foresthill High, the smallest school, shows a significant strength in English but a notable challenge in mathematics proficiency.

The district includes Confluence Continuation High, which serves at-risk students and faces very high chronic absenteeism, though it still achieves an 86.2% graduation rate. A key finding across the district is that mathematics proficiency is a common challenge, with only Del Oro scoring above the district average. The data shows that higher spending does not automatically correlate with stronger academic outcomes, suggesting factors like instructional quality and school culture are crucial for student success.
