Should Teachers Be Judged by Standardized Test Scores?

Should a teacher’s job performance be judged on his or her students’ standardized test score?

Yes, say 80% of U.S. states which subscribe to this theory, but now new research has arrived calling into question whether such scores are a fair measure of a teacher’s job performance.

Researchers from the University of Southern California and the University of Pennsylvania teamed up to determine whether student test scores were a reflection on the quality of teaching. In their newly published study, they failed to find a substantial correlation between scores and the standard of instruction. Teachers that rated highly in a number of ways including principal and student evaluations often had underwhelming test scores. Conversely, teachers who ranked poorly by these other measures had students who scored exceptionally on the tests.

The fact that one facet cannot predict the other suggests that there is a flaw in the way the educational system determines which teachers get to keep their jobs. Speaking to the Washington Post, Morgan Polikoff, a professor and researcher at USC, said, “We need to slow down or ease off completely for the sakes for teachers, at least in the first years, so we can get a sense of ‘what do these things measure? What does it mean?’ We’re moving these systems forward way ahead of the science in terms of the quality of the measures.”

Troublingly, teachers are already actively receiving bonuses or, worse yet, pink slips based upon data that has not yet been proven to be a reliable judge of performance. The national push to make standardized testing the focus of education isn’t benefiting students any more than it is teachers.

The new study is hardly alone in pointing out the disparity between standardized test scores and the characteristics we formerly used to judge good teachers. Not long ago, the American Statistical Association broke down the different factors that account for how well a student does on a standardized test. The group calculated that teacher influence accounts for somewhere between 1 to 14% of a student’s score, meaning that the vast majority of the score is up to factors out of the teacher’s control.

Despite the mounting evidence that test scores are not a good indicator of teacher performance, states are giving growing weight to test scores all the same. 35 states mandate that test scores are a “significant” factor in evaluating teachers, though some have even dictated that it be the “most significant” factor; only ten states do not require test scores to be considered in the teacher evaluation process.

Surprisingly, President Obama’s educational policies are promoting this unfortunate trend. In order for school systems to receive money from the Race to the Top program, they must have restrictive teacher evaluation systems in place.

Teachers already feel enough pressure to teach to the tests, why compound the problem by making their jobs depend on them, too? We stand to undervalue if not outright lose great teachers who pass along the kind of wisdom and thirst for knowledge that standardized tests can’t measure if schools continue down this current path.

no. It'd be better to judge the government's job performance on the number of unemployed. We're used to think if a kid gets bad marks, he is lazy. Or ignorant. The core of problem is Common Core. Well, I believe tests are necessity as well as essay writing, but many kids pass tests only for scores and not for knowledge, as they aren't motivated to study at all. The same can be said about essay writing: kids have to create numerous papers, train writing skills, but eventually more than half of them resort to professionals who offer custom admission essay 2015 in order to get professional help. Common Core has some advantages but it should be reformed as the whole education system, as it's not effective.

Oh this just slays me. Never can a teacher be judged by test scores alone. I understand the need to have a subjective way to evaluate but this is not the way

The last paragraph says it all for me. Good teachers inspire curiosity and a desire to learn - which doesn't necessarily show up in standardised scores.

Maybe we should start judging politicians on how life improves for their constituents. By the number of bipartisan bills they vote for & what they accomplish. I don't think there would be many who made the grade....
A standardized test only tells one what the student can spit back. It has no bearing on critical thinking. They are unfair with questions. I once taught in the Valley in TX & one of the questions had to do with snow & ice - very few valley kids had ever seen either one. A test is only supposed to be administered with 1 thing in mind - what does the student need to learn. It should never be the means by which a person advances to the next grade nor a basis for what a teacher has taught.

Its about time they start looking into this. There are just some people (me included) that have no problem with their daily homework and projects but they just can not test very well--the stress of it and just in general makes test an unfair way of determining whether or not students have actually learned anything.

Are we still debating this ridiculous issue? Any politician who says our children come first, and then bases teacher performance on standardized tests is a liar.

What about parents? I don't care about "judging" them, but they need to be help accountable. They are the first and at times the most effective teachers.
