The most up-to-date DIBELS materials are marked with a 2023 date. These can be accessed through the Testing Materials page. The most significant change is an update to the PSF directions to change one of the example words. In addition to that there was inconsistency with the sounds for vowel-nk sounds in NWF scoring, those were all updated to make the /ng/ sound. There were some items updated to make the measures more culturally sensitive – for example items specifically talking about Native American communities.

The DIBELS 8th Edition team provided the IDEL materials on this website as a courtesy for customers who were uploading IDEL data to the DIBELS Data System. However, the DIBELS Data System recently discontinued support for IDEL, and because we no longer have IDEL experts on staff at the University of Oregon, we determined that it would be best to retire the materials from our website.

New as of April 2023, we proudly present materials adapted for our users in the Australasian region.

DIBELS 8th Edition percentiles and Zones of Growth have been updated. The national sample represents performance of students after a period of unprecedented disruption and challenge to typical instructional practices resulting from the Covid-19 pandemic.

Thank you for your continued use of the DIBELS Data System (DDS). We are pleased to announce that Amplify now operates the DDS.
