Learning Disability Quarterly

The Effectiveness of a Group Reading Instruction Program With Poor Readers in Multiple Grades Rashotte, C. A., MacPhee, K., Torgesen, J. K.

Learning Disability Quarterly, Spring 2001 (Volume 24, No. 2, Page 119)

This clinical study produced the first published data documenting the effectiveness of the Spell Read P.A.T.®program.  The study was conducted in early 1999 in an elementary school in St. John’s, Newfoundland.  It involved 117 students in first through sixth grades.  The key findings were that the SpellRead program :

  1. Made a significant impact on the reading skills of deficient readers in grades 1 to 6.

  2. Improved reading skills were shown after only 34 hours of SpellRead P.A.T.® instruction and the growth in reading skills was not grade specific.

  3. Was effective for both moderately and severely deficient readers and when delivered in groups of 3 to 5 students.

In addition to the extent and breadth of gains, the pace of skill improvement was also quite rapid (see Effect Size scores below), even though students had completed less than one third of the Spell Read P.A.T.® program (34 hours).


Built on Science. Focused on Results.

NOTE: Effect Size is a generally accepted measure of potency (the pace at which the student skills improve) where .2 = small, .5 = medium, ≥ .8 = large.
