Welcome to ATLAS

The Access to Literacy Assessment System- Phonological Awareness (ATLAS-PA) is a free adaptive measure of phonological awareness that is appropriate for children with typical development as well as for children who have disabilities related to speech production. Phonological awareness refers to children’s understanding of the sound structure of language and is a strong predictor of children’s reading achievement.

View the test


ATLAS-PA was developed for children who are 3 to 7 years of age and includes three subtests, including items related to rhyming, blending, and segmentation.

It has four key features consistent with principles of Universal Design and removes barriers of assessment for children with speech production difficulties and/or other disabilities:

(1) requires no spoken responses by utilizing a multiple-choice format;

(2) is web-based so that it is accessible using tablets and laptops;

(3) is an adaptive test, which minimizes testing time; and

(4) includes individualized instructions and opportunities for practice, to make it accessible to a broader range of children.


Use of Test

Each subtest is administered separately, so that scores can be provided for each subtest as well as for overall phonological awareness. Testing time for all three subtests on the adaptive measure usually takes under 10 minutes. A standardized M-score from 15 to 25 (mean of 20, standard deviation 2) is reported, with a short description of how to interpret the score. Also provided with the ATLAS-PA M-score are score descriptors for other published phonological awareness measures. These estimate how a child would have scored on TOPEL, CTOPP-2, or Acadience Phonological Awareness, for her age or grade, where applicable.
