* Public Schools (K-12): The Santa Ana Unified School District (SAUSD) is the main district, and it encompasses numerous elementary, middle, and high schools. The exact number fluctuates slightly over time due to closures, mergers, and new constructions. You would need to check the SAUSD website for the most up-to-date count.
* Private Schools: Santa Ana also has a number of private schools (religious and secular) at various levels (preschool through high school). There's no central, readily available list of all private schools in the city. You'd have to do a more extensive online search to get a complete count.
* Charter Schools: Santa Ana also has charter schools, which are publicly funded but independently run. Again, their number isn't consistently reported in one place and changes over time.
To get the closest answer, you'd need to individually check the websites of the SAUSD and search online for private and charter schools in Santa Ana. Expect the total to be in the dozens, if not over a hundred, including all school types.
