Details | Administering TELL

TELL’s self-delivery is groundbreaking. Students start with an initial tech check to make sure their tablet’s audio and microphone are working properly, and then are introduced to TELL through guided video tutorials that help them navigate TELL and familiarize them with the various item types before seeing any items. They make their own way through the assessment, responding to fun, engaging items that feel more like a game than a test. TELL announces when they’re done. Depending on test type (screener, diagnostic, or progress monitor), tests can take 20–50 minutes.

Convenient, flexible, and scalable, TELL can be used with just one student at a time or with a small to large group.
