Basic orientation
Types of high schools
Independent, faith-based, and public (district, selective, charter, referral).
Updated September 2026
San Francisco offers families a wide set of choices, which is a gift, but can be a little overwhelming at first. The admission criteria, costs, and calendars all change depending on the type of school, so if the categories are new to you, here's a quick definition of each. These are the same types you'll see in the directory.
Independent schools
Other communities might call these nonsectarian "private schools," but in SF they're commonly referred to as independent schools. There are many flavors of schools in this category, but most sub-classifications would only be a reflection of our personal biases. What they have in common is much lower student-to-teacher ratios and the highest total cost of tuition. Many do offer generous indexed or flexible tuition (i.e., discounts), so don't let the sticker price scare you off. Each runs its own admissions process, although most share an application deadline in early January, common essay prompts, and an application platform (Ravenna). Aid usually runs through a shared platform too, most often Clarity or SSS.
Faith-based schools
Faith-based schools are also private schools, but with a religious affiliation. Most are Catholic. The rest are the Jewish Community High School and a few small Christian schools. They typically cost less than the independents, though not always, and each runs its own admissions process. Three of the Catholic schools share a single entrance test, the HSPT, and faith-based schools often have an earlier application date than the independent schools. The three biggest private schools in the city are all Catholic, and between them St. Ignatius, Sacred Heart Cathedral, and Archbishop Riordan enroll about half of San Francisco's private high school students.
Public schools
Public schools are our largest group by enrollment. When we talk about public, we're really talking about four subcategories.
District
District public schools are the standard SFUSD schools, and the bulk of the public options. You don't apply to each one. You submit a single district application, rank your choices, and a citywide lottery places your student. No tuition, no entrance test, and no neighborhood that guarantees a seat. There's more to it, which the SFUSD application walks through.
Selective
There are two selective SFUSD schools that have their own admissions process. Lowell is our academic powerhouse, and it admits in bands. Most students get in on grades and Star test scores, with a smaller share admitted through a fuller review that weighs an essay, activities, and a student's circumstances. Ruth Asawa School of the Arts (SOTA) admits students based on an audition or portfolio. Both are free, and both are their own application inside the public system.
Charter
Charter schools are free and publicly funded, but run independently, outside the district's enrollment. Each sets its own admissions, usually an open lottery, and you apply directly. They tend to be small and mission-driven, and there are only a few at the high school level here.
Referral
Referral schools are alternative and continuation schools, entered by placement rather than choice, for students who need something other than a traditional campus. They sit outside the path this site is built around, so we mention them just to complete the picture, and the directory files them under Specialization rather than Public.

- California Department of Education — Private School Data, 2024-25 (XLSX) — affidavit enrollment by grade for every private school; the three enroll 4,119 of the 8,428 students in grades 9-12 at San Francisco private schools. We stay on the 2024-25 file deliberately: the 2025-26 affidavit is missing St. Ignatius and Archbishop Riordan entirely (27 San Francisco schools and 5,174 students in grades 9-12, against 33 and 8,428), because affidavit filing is self-reported and incomplete in any given year. Recomputing from it would put the three at 28%
