Welcome to the ITEMS Portal!

The ITEMS portal is your entry point into a world of learning in educational measurement. ITEMS modules are its centerpiece, which are relatively short self-contained lessons with various supporting resources that support self-guided learning as well as professional instruction. In addition, you can explore a network of other professional organizations, stay up-to-date via news feeds, and contribute to the success of the portal. Enjoy your learning experience!

New Digital Modules:
