A Truly Innovative Reading Solution


Rapid Gains for Middle School and High School Students

Average Rate of Advancement in Functional Reading Ability

Testing Instrument: Gates-MacGinitie Reading Tests, Comprehension Sub-Set
Testers: Various school systems implementing Read Right tutoring



ALL STUDENTS (n = 1026):
1.82 grade levels of gain with an average 45 hours of tutoring (average/11.0 NCE gain)

1.69 grade levels of gain with an average 46 hours of tutoring (average/10.2 NCE gain)

1.97 grade levels of gain with an average 47 hours of tutoring (average/13.8 NCE gain)


ALL STUDENTS (n = 1,229):
2.23 grade levels of gain with an average 42 hours of tutoring (average/10.7 NCE gain)

2.06 grade levels of gain with an average 45 hours of tutoring (average/10.1 NCE gain)

2.64 grade levels of gain with an average 44 hours of tutoring (average/12.9 NCE gain)


NOTE: The following research was reviewed in 2011 by the National Center on Response to Intervention. The research focused on gains in student reading comprehension with middle and high school students—an age group considered difficult to remediate. The National Center gave the research very high ratings:

  • Scott C, Nelsestuen K, Autio E, Deussen T, and Hanita M (2010). Evaluation of Read Right in Omaha Middle and High Schools, Portland, OR, Education Northwest.

    Findings: Read Right methodology demonstrated "significant positive effect" in a controlled study involving 400+ middle and high school students. Researchers measured an average effect size of .25 after an average 18 hours of Read Right tutoring delivered during one semester (the probability that the results were achieved by chance: p=.000). African American students measured even greater gains: .34 with a probability of p=.007.

Record of Replication:

  • Read Right methodology has been well tested with projects implemented at over 500 sites in 43 states and Canada with more than 3,130,000 hours of tutoring to date. It has been used successfully with over 94,000 students, including students classified as dyslexic, ADD, or learning disabled, as well as Title I students, ESL students, and other “non-labeled” students with reading problems. Projects have included adults (college, community-based, corrections, and workforce literacy) and children and teens of all ages, K-12.
