Welcome to the CLAS Demo!

After over 20 years of research and development, we're delighted to present the first free public demonstration of Lectica's sophisticated new assessment platform—lecticalive—and the world's first computerized developmental scoring technology—CLAS. The CLAS demo is for ages 9 through adult.

Read me! There are two ways to take the demo. (1) signed in as a registered user (best if you want to take an assessment for real) and (2) as an unregistered user (best if you just want to check out the CLAS Demo). Click the button of your choice to get started!
