Health Services Academy (HSA) High School is a free public charter school that is authorized by the Los Angeles Unified School District (LAUSD). As a public charter school, HSA abides by California State Education Code.  ALL students who apply are accepted unless there are more applications than there are seats available.  If the number of pupils who wish to attend HSA exceeds the school's capacity, attendance (except for existing pupils) is determined by a public random drawing.  For more information on the enrollment process for HSA and all Alliance College-Ready Public Schools, click here.
