The evidence behind AmeriCorps' proven program:
Why Reading Corps should be a part of your state's literacy plan.

We have a learning crisis in this country. The good news is, we also hold the antidote.

Reading Corps delivers direct and explicit skill development to K-3 students, giving them the opportunity to practice key reading skills. Reading Corps tutors provide high impact tutoring, one-on-one or small groups, that is based in the science of reading. Provided during the school day, Reading Corps’ evidence-based tutoring supplements core instruction and aligns with a school’s multi-tiered systems of support.

Effective

Reading Corps’ approach - grounded in the science of reading - has proven to be effective in any setting.

Economical

Reading Corps is a tutoring provider that is offered at no- or low-cost to schools. For-profit solutions are more expensive and have yet to demonstrate our scale or results. Reading Corps provides the best value and sustainable results available today.

Scalable

Reading Corps has scaled nationally to benefit 33,600+ students annually across 16 states and the District of Columbia—spanning urban, suburban, frontier, and rural communities—achieving successful outcomes wherever we go. In the 2022-23 school year, Reading Corps supported 1,020 schools in 392 districts.

Evidence-based Interventions

  • Aligned with recommendations from the National Reading Panel and the Institute of Education Sciences
  • Evidence-based interventions build phonemic awareness, phonics, and fluency skills
  • 20 min/day

Data-driven Decisions

  • Screening data to guide student selection and support type
  • Progress monitoring data to evaluate student growth
  • Dosage data, including format and length of support

Expert Training and Coaching

  • Comprehensive and interactive online training on the program and science of early learning.
  • Regular support from a coach at the school
  • Weekly support from a coach with expertise in the program
  • Ongoing fidelity checks

The Evidence

High-impact tutoring delivered through Reading Corps is a proven learning intervention that enables students to catch-up when they are months or even years behind. Our results speak for themselves:  

  • Students who received Reading Corps tutoring demonstrated growth in phonics, reading fluency, and oral reading fluency scores that were equivalent to an extra 50%-90% of a year of schooling.
  • After a single semester, the average Kindergarten student in Reading Corps performed twice as well as their peers.
  • Our training and coaching model enables people of all backgrounds to be effective tutors.
  • Reading Corps has been identified as having the highest level of evidence by the Evidence for ESSA clearinghouse at Johns Hopkins University.

Study Findings

Findings

Commissioned by AmeriCorps and conducted by ICF, this evaluation demonstrated substantial return on investment driven by high school credential attainment for participants, improved employment and earnings outcomes for AmeriCorps members, and long-term cost savings to the government.

Findings

Led by the NSSC, this study advanced previous evaluations by including a distal outcome of reading achievement. Although no effects were observed in early grades, large effects were observed among 2nd and 3rd grade students--equating to roughly 18 additional weeks of instruction.

Findings

Conducted by NORC at the University of Chicago, this study observed statistically significant and meaningful effects for kindergarten through 3rd grade students of support. Larger effect sizes were observed among Black or African American students and English Language Learners.

Findings

Conducted by NORC at the University of Chicago, this study observed statistically significant and meaningful effects after one semester of support for all students except second grade, where statistical significance was not achieved. Among kindergarten and first grade students, the impact of Reading Corps was particularly among English Language Learners.
