Local school districts across the Hudson Valley and statewide began the second round of the controversial Common Core exams.
Students in grades three through eight began the three days of math testing.
The scores don't count toward student grades, but they are factored into teacher and school rankings.
The tests have faced backlash from parents who say their kids are being tested too much.
Teachers argue the testing is not a fair reflection of their skills.
Tens of thousands of parents statewide had their children opt out of last week's Common Core tests.
