I am a graduate student in psychology, and this is the WORST textbook I have ever used. It is poorly written, confusing, and doesn't define clearly even the most simple concepts it is trying to explain. I have to go online to look up definitions and concepts.

I am a graduate student, half-way through my program and this is not a good introduction to the subject of Psych Testing. The wording is vague, the text skips around so much that finding answers to even simple questions requires extensive hunting. It is unnecessarily difficult to understand. Our professor says it will be a good reference book down the road, but I intend to sell it the minute I've completed the course and then go on to find another book so that I can get a better handle on the subject
