AEPS Interrater Reliability Certification

How can you ensure that you or your staff use observation skills to score AEPS® correctly and consistently? Add AEPS Interrater Reliability Certification to your professional development toolbox!

Invaluable for states and districts that require teachers to demonstrate reliability on assessments, these online certification modules help you use the AEPS Test accurately to promote real progress for every child.


The AEPS Interrater Reliability Certification modules for use with AEPS, Second Edition are available now. An interrater reliability certification for use with AEPS-3 is coming in 2023. 

How it Works

The AEPS Interrater Reliability Certification module takes about 3–4 hours to complete. In the module, AEPS users view a narrated training presentation and watch video examples of real children. While observing children in naturalistic videos, users take a practice test and review the correct answers. Then, users complete the certification test, observing and scoring items across every area of the AEPS Test for Three to Six Years: fine motor, gross motor, adaptive, cognitive, social-communication, and social. The online system calculates and reports overall results and results by area immediately—and gives users a chance to review the correct answers and rationale for each score to build their knowledge. Users who score 80% or higher on the test are certified reliable for three years and can print a certificate. Those with scores that fall below 80% can review the first test and then take a second test to try for certification. (A user’s access period for the certification module is valid for one year from the date of purchase.)

When AEPS users are certified, you can be confident that your assessment information is reliable: for every child, across observers, across different circumstances, and on different days. And more accurate AEPS results mean better intervention and instructional decisions—and better child outcomes.
