A Truly Innovative Reading Solution

Evidence of Effectiveness

Read Right is Based in Brain Science & Validated through Research 

If you would like to know more about the science underlying Read Right methodology, we recommend two publications by Dee Tadlock, Ph.D:

Read Right Studies and Other Recognition


Examples of the Scientific Bases Underlying Read Right's Methods

Independent, Controlled Research:

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 .23 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.

Research is Highly Rated by the National Center on Response to Intervention:
Education Northwest's independent study examining the effectiveness of Read Right methodology was reviewed in 2011 by experts at the National Center on Response to Intervention. The experts found the research to be reliable and of high quality. Examine the ratings here.

Read Right Out-Performs Striving Readers Projects
Researchers prefer effect size as a measure because effect sizes can be compared from study to study. In an examination of effect sizes, Read Right tutoring out-performed reading programs studied as part of the federal Striving Readers project. Consider this:

  • The best Striving Readers project studied produced an effect size of .29 after one full school year of instruction.
  • The best Read Right school studied produced an effect size of .58—after one semester of tutoring. Read Right received twice the result in half the time.

Record of Replication:

The Read Right program has been well tested with projects implemented at over 587 sites in 44 states, China, and Canada with more than 4,413,300 hours of tutoring to date. It has been used successfully with over 109,900 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.
