Why some San Carlos schools show “not ranked”

San Carlos uses a distinctive grade structure. Its lower elementary schools serve kindergarten through third grade, so they only test third graders, too few tested grades to assign a statewide rank. Science scores are also unavailable at these schools because the state science test (CAST) is only given in grades five, eight, and once in high school, while math and English are tested every year from third through eighth grade. The district's upper elementary and middle schools, which include the tested grades, are ranked normally.

Beyond the ratings

Academic Culture and School Community

Quick summary

San Carlos is known across the Peninsula for strong public schools, sustained in large part by an unusually engaged community. A defining local fact is that the district is one of the lower-funded in the county, and parent and community fundraising helps close the gap. For high school, the assigned campus depends on address and matters a great deal, since the two options differ significantly.

A strong district powered by its community

The San Carlos School District consistently ranks among the stronger districts on the Peninsula, with its two middle schools placing in the top 2 percent of California schools and its upper elementary schools in roughly the top 5 to 7 percent. What makes San Carlos distinctive is how it gets there. The district is one of the lower-funded in San Mateo County, and community support fills much of the gap. The San Carlos Education Foundation raises over 3 million dollars a year, and together with parcel taxes and grants, community funding provides roughly a quarter of the district's budget. That money supports art and music, technology, counseling, and social-emotional programs that state funding alone would not cover.

The distinctive grade structure

San Carlos uses an unusual tiered structure. Children attend a neighborhood lower elementary school for kindergarten through third grade, then move to one of two upper elementary schools for grades four and five, and then one of two middle schools for grades six through eight. Feeder patterns generally pair certain lower schools with a specific upper elementary and middle school, though placement can shift with capacity, so families should verify their pathway with the district.

High school: the assignment matters

For high school, San Carlos students attend the Sequoia Union High School District, and which campus depends on the home's address. Most of San Carlos, generally the central and northern neighborhoods, is assigned to Carlmont High in Belmont, one of the top-ranked high schools in the state, known for extensive Advanced Placement offerings, a biotechnology pathway, and strong performing arts. Southern San Carlos and certain option zones are served by Sequoia High in Redwood City, home to the district's International Baccalaureate Diploma Programme alongside traditional AP courses. The two schools differ significantly in profile, so the high school pathway is worth confirming carefully by address.

Additional public school options

Beyond the assigned campuses, San Carlos families can pursue several other public options in the Sequoia Union district. One is Middle College High School on the Cañada College campus, where eleventh and twelfth graders earn college credit. Public charter schools open by lottery include Design Tech High School, known as d.tech, located on Oracle's Redwood Shores campus, and Summit Preparatory and Everest in Redwood City. Availability and admission vary, so confirm current details with each program.

What families say

The perspectives below reflect my own research across public data, local forums, and family reviews rather than verified facts, and are worth reading alongside the verified scores above. Families consistently describe San Carlos as a tight-knit, education-focused community where parent involvement runs high. Many cite the schools as the main reason they moved to the city. Some note that the high school assignment is a significant consideration, and that families pay close attention to which campus their address feeds.

The bigger picture

San Carlos offers a strong public school path from elementary through middle school, backed by a community that invests heavily in its schools, and access to a range of high school options. The right fit depends on the family and, importantly, the specific address. We encourage buyers to verify school assignments and visit schools directly.

FAQ

Common questions

How good are San Carlos schools?

The San Carlos School District is well regarded, with its two middle schools ranking in the top 2 percent of California schools and its upper elementary schools in roughly the top 5 to 7 percent. Its lower elementary schools show as not ranked because they only serve kindergarten through third grade. For high school, most students attend Carlmont High, which ranks among the top few percent statewide.

Which high school will my San Carlos home attend?

It depends on the address. Most of San Carlos, generally the central and northern neighborhoods, is assigned to Carlmont High in Belmont. Southern San Carlos and certain option zones are served by Sequoia High in Redwood City, where families may sometimes choose between the two. Because the two schools differ significantly, always verify the exact assignment with the Sequoia Union High School District.

Why are some San Carlos elementary schools not ranked?

The district's lower elementary schools serve only kindergarten through third grade, so they test just one grade level, too few for a statewide ranking. Their students continue to the upper elementary and middle schools, which are ranked normally.

What is the San Carlos Charter Learning Center?

It is a tuition-free K-8 public charter school, notable as the first charter school in California, open to district students through a separate lottery rather than by address. It is independent of the neighborhood schools.

Why are San Carlos schools so dependent on fundraising?

San Carlos is a state-funded district under California's LCFF formula, rather than a community-funded Basic Aid district, which makes it one of the lower-funded per pupil in San Mateo County. Community support, led by the San Carlos Education Foundation, raises over 3 million dollars a year, which together with parcel taxes and grants provides roughly a quarter of the district's budget to fund art, music, technology, and counseling.

What other high school options do San Carlos families have?

Beyond the assigned Carlmont or Sequoia High, San Carlos families can pursue other Sequoia Union options, including Middle College High School, and public charter schools by lottery such as Design Tech (d.tech), Summit Preparatory, and Everest. Availability varies, so confirm with each program.

Are all San Carlos neighborhoods in the San Carlos School District?

Almost all are, but not every home. Part of Alder Manor, in the city's southwestern corner near the Redwood City border, is a Redwood City School District island: those homes carry a San Carlos address but are zoned to Clifford School for K-8 rather than to San Carlos schools. Other Alder Manor homes stay in the San Carlos School District. Because the boundary runs by parcel, always verify your assigned schools by exact address.
