The SAT is a rite of passage for many high school seniors, but not everyone takes the test. Students not planning to attend college, for example, may opt to save the time and expense, and many students take the test as juniors.
The percentage of seniors who took the SAT varies among the nine Bay Area counties, ranging from more than half to just over a third.
1. San Francisco
3. Santa Clara
4. San Mateo
5. Contra Costa
More than half of students in counties with large cities took the test, while the more rural North Bay counties lag behind, with Solano and Sonoma counties falling below the statewide rate of 45.73 percent.
