Some students at Santa Fe High School and Capital High are protesting over state-required testing.
At Capital, some students briefly tore down a gate to leave campus Monday.
About 40 Santa Fe High students reportedly walked out of class and gathered for a indoors "town hall" style meeting with the principal.
The students are upset about the standardized tests known as the Partnership for Assessment of Readiness for College and Careers.
The all-computerized exam is designed to test students' knowledge of the newly adopted Common Core Standards, which encourage critical thinking and essay writing.
The tests are expected to take up to nine hours over several days next month.
Some students say the tests are too hard and the pilot PARCC testing periods are taking time away from classroom instruction.
