Every year California students in third through eighth grades, plus high school juniors, take the Smarter Balanced test as part of the California Assessment of Student Performance and Progress, or CAASPP.

The test is divided into math and English sections, and the score is broken into tiers of Exceeded Standards, Met Standards, Nearly Met Standards, or Did Not Meet Standards. The top two, Met or Exceeded Standards, are considered to be a “pass.” The test scores are for evaluating schools and don’t impact individual students.

The following are the percentage of students in each Bay Area county who “Met or Exceeded Standards” in the math test in each Bay Area county. The tests were administered late in the 2017-18 school year and results released in October 2018.#1. Marin — 57.47% students “Met or Exceeded Standards”#2. Santa Clara — 56.25% students “Met or Exceeded Standards”#3. San Mateo — 53.11% students “Met or Exceeded Standards”#4. San Francisco — 49.71% students “Met or Exceeded Standards”#5. Alameda — 48.6% students “Met or Exceeded Standards”#6. Contra Costa — 44.14% students “Met or Exceeded Standards”#7. Sonoma — 38.61% students “Met or Exceeded Standards”#8. Napa — 34.29% students “Met or Exceeded Standards”#9. Solano — 33.3% students “Met or Exceeded Standards”[bar color=”Accent-Color” title=”#1.

In fact, Marin, Santa Clara and San Mateo counties had the second, third, and fourth highest math scores in the state, respectively. Those counties’ scores trailed only Alpine County, which tested 56 total students.
