Research & Evaluation
MORE THAN 25 YEARS OF DOCUMENTED SUCCESS WITH MORE THAN 2 MILLION STUDENTS
Annual evaluation results for the United States are consistent for more than 25 years of service and include more than 2 million students. No other reading intervention has such an extensive database and such strong accountability.
Over the past 25 years, about 75% of students who completed the full 12- to 20-week series of lessons met grade-level expectations in reading and writing.
Reading Recovery and Descubriendo La Lectura Student Results 1984-2011
Children taught: 2,059,819
Children who completed intervention: 1,551,444
Children who successfully discontinued lessons*: 1,209,527
*As soon as students can read within the average range of their class and demonstrate that they can continue to achieve, their lessons are discontinued, and new students begin individual lessons.
In the U.S., evaluation is conducted by the international Data Evaluation Center (IDEC) located at The Ohio State University. National results are reported annually by IDEC and posted on its website (see link below). Because accountability is a key part of Reading Recovery, administrators receive annual reports at the teacher, school, and district levels.
The What Works Clearinghouse independent review of Reading Recovery's experimental research clearly establishes the effectiveness of the intervention based on scientific evidence (see link below).
