What Works Clearinghouse (WWC) Documents Reading Recovery’s
Scientific Research Base
The What Works Clearinghouse (WWC), a branch of the United
States
Department of Education (USDE) and the Institute of Education
Sciences (IES), released
a 3-year independent review of the experimental research on Reading
Recovery in March 2007. This authoritative, independent assessment
clearly establishes that Reading Recovery is an effective
intervention based on scientific evidence.
The WWC found that Reading Recovery has positive effects—the
WWC’s highest rating—on students’ alphabetics skills and general
reading achievement. They found potentially positive effects, their
next highest level of evidence, on fluency and comprehension
outcomes.
The report includes an improvement index to reflect the strength of
the Reading Recovery intervention. Scores on this index can range
from -50 to +50.
The improvement index scores for Reading Recovery students show
large and impressive effect sizes.
No other beginning reading intervention has strong scientific
evidence across all four domains, and no other intervention was
judged to have positive effects on general reading achievement.
