Age norms (equivalents) are not provided for items on the AEPS-3 Test. Choosing targets for intervention should not be based on children’s ages; rather, their status in each developmental area should dictate where intervention/teaching activities should begin. For children who are delayed or lack skills in a developmental area, it is critical to begin at their developmental level, which may be very different from their age. For example, age norms indicate that a two-year-old can walk; however, for a two-year-old who has yet to crawl, targeting walking intervention activities is inappropriate. That child should be working on activities designed to enhance creeping instead.

AEPS-3 items are arranged into developmental sequences that are appropriate for most, but not all children. This makes age norms irrelevant for a test/curriculum designed primarily to help children gain skills appropriate to their developmental level.
