Summary:
ZIP code 94010 has two high schools serving grades 9–12 in San Mateo Union High School District: Burlingame High, a comprehensive school with 1,583 students, and Peninsula High (Continuation), with 123. In 2025–2026, their simple average was below the state in ELA, math and science, but the area average does not describe either school well. The most important finding is the sharp divide between the two schools’ reported results.
Burlingame High stands out at the top: it led in every subject, with 76% proficiency in ELA, 61% in math and 57% in science, all above state results. Peninsula High (Continuation) was below the state in all three subjects, at 10% in ELA, 3% in math and 12% in science. The schools’ gaps were 66 points in ELA, 58 in math and 46 in science. The difference also shows in completion and attendance: graduation was 98% at Burlingame High and 81% at Peninsula High (Continuation); chronic absenteeism was 10% and 74%, respectively.
Scores fell at both schools in ELA and math from 2024–2025 to 2025–2026; science also fell at Burlingame High, while Peninsula High (Continuation) rose 2 points in science, still trailing state improvement. SchoolDigger’s statewide percentile for Burlingame High declined from the 98th to the 94th over three years; Peninsula High (Continuation) moved from the 6th to the 17th, despite a small dip in the latest year. In 2024–2025, Peninsula had a lower student-teacher ratio (13.2 versus 19.6) and a higher free/reduced lunch eligible measure (50% versus 13%); these are context, not explanations for score differences. The schools differ in size and type, so their results should be considered in that context.
