When you're writing a test, you really don't want to make any mistakes. And yet, teachers, educational test writers, and even those who specialize in assessment make them all the time. In this book, veteran testing professional Jan Gleiter breaks down the most common problems test-writers face--and tells you how to solve those problems as you craft tests. Walter MacGinitie, author of the Gates-MacGinitie Reading Tests, praises the book, saying that it has the potential to bring about a genuine improvement in testing. It gives sound general advice and sensible specific guidance, using many clear examples to show how test questions and testing practices can be improved. The writing is fresh and direct, making the principles easy to understand and follow.
