City Heights Prep Charter School in College Area is a tuition-free San Diego public charter school serving grades 6 through 12 at 4260 54th Street in the 92115 ZIP. The school opened in September 2012 and operates under the San Diego Unified School District charter authorization, enrolling approximately 158 students with a student-teacher ratio of 17 to 1 across nine full-time teachers and one full-time counselor. The compact enrollment produces smaller class sizes than most SDUSD high schools, and the campus sits on the same 54th Street block as other education-focused operations in the College Area charter ecosystem that includes Darnall Charter School nearby. City Heights Prep holds Title I schoolwide designation, reflecting a student body where 88 percent qualify as economically disadvantaged, and the school ranks among the most diverse public high schools in California at number 417 on Niche's diversity index. The STEM curriculum includes robotics, 3D printing, and coding coursework that feeds into career and technical education pathways. The 54th Street campus puts students within two miles of SDSU, connecting the charter's college-preparatory mission to the university infrastructure south of Montezuma Road. Student athletics and recreation extend beyond the campus to facilities across the College Area, including the Kroc Aquatic Center on University Avenue. The school maintains rolling enrollment and provides individualized academic support through its low student-to-counselor ratio.
