The purpose of the MEASUREMENT PRIMER program is to present basic concepts used in educational and psychological measurement. The term primer in this context means "to prime" or prepare you for additional study in assessment applications.

There is no charge for use of this program, and no limitation on copying and/or printing these pages. However, because of the interactive design, it is likely to "make sense" only in the context of a browser, and there is extensive white space, so the printed page count will be extraordinary. If you want to have the option for offline use and review, you may want to consider the Personal Version designed for use on your own computer. For more information, click here.

Basic measurement content is presented in MEASUREMENT PRIMER on individual information screens. Periodically there will be review questions for feedback and direction for additional study.

You "travel" through this program using prompts which appear on the screen. For example, click the "up arrow" to move back to the start of this page or the "down arrow" to move to the study topics.
