High Schools in Imperial Unified

Summary:

The Imperial Unified school district operates two high schools serving grades 9-12: the large, comprehensive Imperial High and the much smaller alternative Imperial Ave. Holbrook High.

Imperial High is the district's standout performer, with strong academic results, an exceptional 97.6% graduation rate, and a low dropout rate, consistently ranking well above state averages. In contrast, Imperial Ave. Holbrook High serves a very small population and faces significant challenges, with much lower proficiency rates and a 60% graduation rate, though it showed notable improvement in its statewide ranking last year.

Key differences include a dramatic gap in chronic absenteeism, which is very high at Holbrook, and a concerning mathematics proficiency rate at Imperial High that is below the state average. The district's overall strong graduation rate is driven by Imperial High's success, but the data highlights the distinct roles and student outcomes of these two very different schools within the same Imperial Unified system.
