View the case study white paper here.

Date: Spring 2019

The purpose of the study was to determine if there was a correlation between the Nessy Reading and Spelling Target Assessment, and The Slosson Oral Reading Test Revision 3 (SORT-R3). A high correlation of .82 was found to exist indicating that the Nessy Target Assessment is an accurate measure of pupil reading level or reading age, and that the assessment can be used to determine initial placement in the literacy curriculum, and to monitor student progress in oral word recognition.
