National Student Support Accelerator posted RCT results for Chapter One - a program that provides two years of tutoring to struggling readers in grades K-1. Quick take: High-quality RCT finds small impacts (not statistically significant) on reading at the 2 year mark - i.e., the end of 1st grade.
Program:
-
Chapter One provides 2 years of tutoring to struggling readers in grades K-1, delivered by part-time tutors in the classroom who provide short bursts of instruction to individual students each week over the course of the year. This is a low-cost program - about $375-$450/student.
Study Design:
-
The study randomly assigned 818 kindergartners in 13 Broward County FL schools to tutoring vs control (usual services). 93% were Black or Hispanic, & 56% low income. Based on careful review, this was a high-quality RCT (e.g., baseline balance, low attrition on district reading tests).
Findings:
-
At end of 1st grade, the study found no statistically significant effect on the district test of reading with comprehension. (The non-significant effect was 0.10 standard deviations - equating to ~7% improvement over the annual reading gain otherwise expected in 1st grade.)
-
The study found a possible effect on pre-reading skills (e.g., phonics, phonemic awareness): effect of 0.11 (not statistically significant) and reduction in percent at-risk from 54% C to 45% T (statistically significant). Such skills may or may not lead to future gains in actual reading; longer-term follow-up is needed.
-
The study report highlights larger pre-reading effects found in program-administered (as opposed to district-administered) tests, but these are less reliable measures and vulnerable to bias.
Comment:
-
The study is ongoing, and it’s possible that impacts on reading will appear in future grades - so stay tuned.
