Richard L. Slosson
Revised by: Charles L. Nicholson
Supplementary Manual: Sue Larson

Age:  Preschool through Adult
Administration:  3 to 5 minutes, Individual

    The Slosson Oral Reading Test (SORT) has historically held a respected position in education as a quick screening test to determine a student’s reading level. The SORT-R3 continues in the tradition and purpose that Richard L. Slosson intended, remaining as a quick and reliable screening test. With the ability to target word recognition levels for children and adults, the SORT-R3 can be used for regular education testing populations and for many special testing populations.

   Developed from several sources, such as Dolch and other reading references, the SORT-R3 Word Lists contain 200 words in groups of 20 words. Target words have been carefully selected to represent a steady progression of difficulty from preprimer through the high school level. The design and layout of this test allows for quick individual administration, taking 3-5 minutes on average to complete.
SORT-R3 Complete Kit includes:
  • Manual
  • Scannable Score Sheets (Set of 50)
