The newly elected chancellor of the state's Board of Regents gave a boost to parents who have had their children opt out of Common Core exams moments after her appointment Monday.

"If I was a parent and not on the Board of Regents, I would opt out at this time," said Betty Rosa, a Common Core critic who was previously superintendent of schools in the Bronx.

Long Island administrators welcomed the endorsement.

"I was thrilled to hear that," said Bill Johnson, the superintendent of Rockville Centre. "What she did was to tap into the feelings that so many of us have about the test itself."

Johnson says he disagrees with the notion that Common Core testing is a good way to evaluate students or teachers.

Jeannette Deutermann is the founder of Long Island Opt-Out, which last year saw 80 percent of students on the Island boycott the math and English assessments. She says she is pleased with Rosa's appointment.

"We've moved so far away from what's best for kids, and it's really enough is enough," Deutermann says. "It's time to get back on track, and we're happy now there's a leader that could lead us in that direction."

Gov. Andrew Cuomo has eased his firm support of the Common Core and pledged to overhaul the curriculum.

This year's English and math exams are set for April.
