Teaching to the test is malpractice

"For every complex problem, there is an answer that is clear, simple - and wrong."


H.L Mencken

Testing is not teaching.

If you want proof of why, you need not look any further than this:

Learning is messy. Real learning is really messy. Testing is, if nothing else, orderly. See the problem?

Talk to any test-maker or psychometrician, and they'll tell you the tests were never devised to make large sweeping, all-encompassing inferences. Even those who speak in favor of using test scores in moderation in low-stakes contexts understand that tests are merely a small sample of a much larger domain that we want to know about, and that great caution must be made in making inferences based on these tests.

So even if we lived in a fictional world where test scores were valid, reliable and objective enough to make sweeping inferences about student achievement, we would have to still admit that the tests can't measure everything.

In their book, The Myths of Standardized Tests, Phillip Harris, Bruce Smith and Joan Harris aptly describe the danger of teaching to any test:

You'll often hear someone say that a good test is one that teachers should be pleased to teach to. But this proposition concerns us. When it comes to whether teaching to the test is a worthy goal, we don't worry so much about the items on the test. If we don't overinterpret what the tests are capable of telling us, we shouldn't do too much damage. However, we think that a far more important issue is almost always overlooked in policy discussion: what's not on the test.
So what kinds of things aren't on tests?

Gerald Bracey offers the start of a list in his book Setting the Record Straight:


  • creativity
  • critical thinking
  • resilience
  • motivation
  • persistence
  • curiosity
  • endurance
  • reliability
  • enthusiasm
  • empathy
  • self-awareness
  • self-discipline
  • leadership
  • civic-mindedness
  • courage
  • compassion
  • resourcefulness
  • sense of beauty
  • sense of wonder
  • honesty
  • integrity
If these are some of the things tests don't even try to measure, perhaps the use of test scores as a solution for the complex problem of measuring learning is in fact clearly and simply wrong.

  1. Thank you, Joe. As a HS Special Education Teacher in NYS who co-teaches US History I am totally in alignment with the thoughts on the subject that you've expressed here. The teacher I work with has told the students hundreds of times this year something like, "I've written the tests so I know what's on them." Any deviating from the known content is not tolerated; in fact, if I happen to add anything to the class I'm often ignored. (That raises another problem: this isn't "co-teaching.") I'm grateful for having some of the students in Resource Room so I can supplement the teaching with possibilities for actual learning.

  2. As a parent, I say amen to all of the above. Not every child tests the same way nor do they learn the same way. Testing really prohibits realizing what a child has actually learned. Test anxiety is real and kids who exhibit such do poorly on the tests and they then develop the stigmata of being labeled "stupid" or "dumb" or even worse "retarded". I hate standardized tests for kids. They prove nothing. I also dislike the no child left behind garbage attached to the standardized tests since every child now will pass, even if not ready to advance to the next grade level. But alas, I'm not a teacher. So guess it's a good thing you all don't have to carry "malpractice" insurance like doctors do. Mrs. E :)

  3. Hey Joe,

    Nice article. I like that you've detailed your thoughts, but I do have some issue with what you wrote (or rather, how you wrote it).

    I have written a response to what you've written here: http://blog.gnowledge.com/2011/06/03/testing-to-the-teacher/

    Just thought you should know.
