Some parents are calling for students to boycott the Illinois standards achievement test at Chicago Public Schools.
The ISAT will help determine if students will be eligible to attend elite schools.
The parents protesting the test, say they would rather students have two weeks of learning instead.
About 500 students at 29 schools will not be taking the tests, which are set to start next week.
If less than 95% of students take the test, the district would be out of compliance with the No Child Left Behind Law, putting federal funding at risk.
