The kindergarten through eighth-grade students of Rockville Centre sit for computerized tests in math and English several times a year. None of them ever refuse to take the tests, according to Superintendent William Johnson.

“Wait, actually never?” I asked Johnson Tuesday.

“I’ve never heard of one of our students opting out of the adaptive testing,” he replied.

That’s particularly notable because the opt-out rate in Rockville Centre for the state’s usual standardized tests varies from 40 to 70 percent, depending on grade level. It’s also notable because these computerized adaptive tests Rockville Centre administers by choice are far better than the ones it’s required by the state to give.

Rockville Centre’s students take supplemental tests devised by the Northwest Evaluation Association, as do students in at least 20 other districts on Long Island. The tests are adaptive, meaning wrong answers are followed by easier questions, and correct answers by harder ones.

“Adaptive tests hone in on exactly where a child is proficient very quickly,” Johnson said. “And unlike the state’s tests, they can get as hard and as easy as they need to show what the highest and lowest achievers know, even if it’s way above or below grade level.”

Adaptive tests take far less time to pinpoint a student’s proficiency, typically just 45 minutes, while traditional tests might last three hours. They waste little time on questions that are far too easy or far too hard.

Adaptive tests don’t have to be administered to all students on the same day because every test is different. Traditional tests, whether taken on paper or computer, must all be administered on the same day so the questions cannot be passed on to other students.

Tuesday, computer problems across New York during the administration of required English tests caused serious issues. With adaptive tests, which in Rockville Centre are administered throughout September, January and June, one day or even several days of glitches wouldn’t be a disaster.

Adaptive tests are scored on a multiyear continuum for each student. That means progress can be charted over an entire school career as students go from, for instance, a score of 100 in math in first grade to a score of 900 by eighth grade.

Adaptive tests are scored quickly. That means teachers quickly find out what to address for each student based on individualized results. Traditional tests take longer to reveal less.

The political battle over standardized testing and its place in teacher assessment in New York has raged for a decade. The strongest point for the opt-out advocates’ case is the weaknesses of the state tests.

Moving to adaptive tests and proving to parents and teachers how well they work are the best ways to overcome opt-out rates of 50 percent on Long Island and 20 percent statewide.

It is reasonable to judge teachers at least partly by how much their students learn. Teaching children is the job. But it’s also reasonable for teachers and parents to expect the tests to be well-designed, valid and useful.

If no one opts out of the adaptive tests in Rockville Centre, it’s at least possible few would opt out of such tests if they became the state standard — and a part of how teacher success is measured.

And then, if opt-outs did continue, we would know they were all about the teachers and not at all about the tests.
