Standards for Educational and Psychological Testing tells readers everything they need to know about testing accurately and ethically, from classroom to counseling office to career.

A Test Without Standards

Your teacher hands out a test on simple addition. You're ready to ace this thing. After all, you have been adding since you were a baby. Mrs. Krause sets the paper in front of you, and you see that the entire test consists of word problems written in a foreign language you have never seen. Immediately, you foresee your final grade in math plummeting into an abyss of unfair testing.

Well, after you fail the Slavonic math test, you can go to the library and open up Standards for Educational and Psychological Testing to build a case against this test destroying your math grade.

Standards exists to provide guidelines for fair and accurate testing. Associations of psychologists (American Psychological Association) and educators (American Educational Research Association and National Counsel on Measurement in Education) worked together to develop this book, which is used and recommended by professionals in those fields as well as policy-makers whose work includes education. And perhaps even well-informed students who want to prove that they shouldn't need to know a foreign language to pass a math test.

Mostly, Standards is used for standardized tests. However, since Standards does everything possible to create and encourage fairness, you should be able to build quite a case for yourself. Let's take a look at each section of the book.

Part I: Test Construction, Evaluation, and Documentation

Our first stop on the fairness patrol is a visit to the test maker. Standards directs test makers to ensure that their tests only measure the one thing they say they test. In our case, that thing is addition. Our test maker, however, accidentally let a little bias sneak in by writing the test in a foreign language. Bias exists when certain groups will do better or worse based on something irrelevant to the test. For instance, a group of students who speak Slavonic will excel on our math test whether they know how to add better than us or not.

Fair and accurate testing starts with a test maker carefully hunting for bias by trying out this test to ensure that only addition is being tested (or whatever the subject may be). This might mean translating the test into any language represented by the test group.

This also might mean explaining cultural references. For instance, a bad question on an addition test might read, 'Five new reindeer join Santa's usual team. How many reindeer are on the team now?' This question assumes that the test taker has cultural knowledge about the number of reindeer on the team. The question should say, 'Five new reindeer join Santa's usual team of 13. How many reindeer are on the team, now?' This way, the test taker who isn't familiar with Santa, but knows how to add, will have all the needed information.

Since tests are never completely perfect, Standards also tells test makers that they are responsible to make clear exactly what the test has been proven to show and its margin of error. The margin of error indicates just how accurate the test is predicted to be.

For instance, let's say you study your addition facts for the retest you have argued yourself into, but you only study the addition facts for numbers 0-8, leaving off the 9s. In reality, you now know 90% of addition facts.

If the test happened to leave off all the 9s, the test would show that you knew 100% of addition facts, and if it consisted only of 9s, the test would show that you knew 0% of addition facts.

Neither of these would be accurate tests. As the test maker tests her tests, she tries to reduce the margin of error as much as possible and then reports whatever margin of error remains.
