Through extensive research, the AEPS-3 developers have established empirically validated cutoff scores that can be used for determining eligibility. Automated eligibility reports can be easily run for children in the AEPSi system, and cutoff scores are included in the print materials. (Note that these cutoff scores do not correspond to age equivalents or percent delay.)

Since publication of AEPS-3, subsequent rounds of field test data expanded the sample size at targeted age intervals and resulted in adjusted cutoff scores in seven developmental areas in 2022. These cutoff scores were generally higher than previously published cutoff scores across most areas of AEPS-3. Additional analysis with early childhood experts was undertaken on the cutoff scores in the Social-Communication area and scores were adjusted further in 2023.
