High schools are scored on their own scale — never ranked against other levels.

The high school years

61 points separate Burlingame High (84) from Peninsula High (Continuation) (22) — at this level, which school matters more than which district.

0100
Strong Solid Developing Needs Support district avg state avg

61 points separate the strongest and weakest of these 8 high schools — the average hides more than it tells.

1 continuation/alternative school not plotted — it ranks within its own class, not on this statewide axis.

The strength

Burlingame High (84/100) holds the Strong band — 48.6% of its students exceed the state standard, against a level average of 34.1%. 6 schools classify as Strong All-Around — no weak dimension we measure.

The catch

61 points separate the top and bottom high schools — the district average won't predict the school in front of you.

What it means for your family

If you're choosing a neighborhood

The 61-point spread means the district average is nearly meaningless for an address decision — the zoned high school is the whole decision. The strongest attendance-zone candidate is Burlingame High at 84/100 — confirm the exact boundary with the district before the house.

If you already live here

1 of the 8 ranked schools is a charter — enrollment paths that don't depend on your address. If your zoned school sits low in the appendix below, those lotteries and applications are the levers worth the paperwork.

If your kid is enrolled now

A band is a position, not a prophecy — a school's number can move without your kid's experience moving with it. Ask your school two questions: what happens for a kid who arrives behind, and what the classroom looks like for one who arrives ahead.

The strongest-scoring campus:

The top scorer district-wide — confirm enrollment zones with the district, and visit before you decide.

What this page can't see: whether a campus feels safe and glad at 8 a.m. If a path above looks workable, the next step is a visit.
