DENVER — Thousands of Colorado students will get an early start on the new online standardized test Partnership for Assessment of Readiness for College (PARCC) this week, but it’s not without controversy as some parents are opting out.

There have been months of controversy surrounding standardized tests in general and there is a lot of concern coming from every side.

The main question is whether districts will lose money for students who don’t show up for testing.

Phase 1 of PARCC testing doesn’t officially begin until March 9, but thousands of students can get an early start this week.

PARCC is designed to measure how students perform in English and match in third through eighth grades.

But some parents say state tests take up too much instructional time, that it doesn’t accurately measure a student’s knowledge or performance and there are too many tests put on students in general.

Recently, the State Board of Education voted to not hold districts accountable if test participation dips below required levels because of parents opting their children out of testing.

And that’s why some are choosing to sit their kids out this week.

But state and federal requirements say all students must be tested and if participation dips below 95 percent, districts and schools face consequences.

Districts could see a lowering of accreditation and possibly lose millions of dollars of federal funding.
