Abstract
This study examines the impact on student achievement of high-dosage reading tutoring for middle school students in New York City Public Schools, using a school-level randomized field experiment. Across three years, schools offered at least 130 hours of 4-on-1 tutoring based on a guided reading model, which consisted of 1-on-1 read alouds, independent reading, vocabulary review, and group discussion. We show that, at the mean, tutoring has a positive and significant effect on school attendance, a positive, but insignificant, effect on English Language Arts (ELA) state test scores and no effect on math state test scores.

Experimental Design
Experimental Design
The list of sixty schools were randomly assigned to one of three groups – the treatment group consisted of twenty schools that were assigned to be a part of NYC’s Middle School Quality Initiative and added 2.5 hours of after-school programming which included 4-on-1 tutoring and the main control group consisted of twenty schools that were assigned to be a part of NYC’s Middle School Quality initiative. A secondary control group serves the purpose of a “pure” control.
Experimental Design Details
Randomization Method
Matched triples were assigned by ordering the set of sixty schools by sixth grade enrollment and their average proficiency rate in math and ELA. Then we designated every three schools from this ordered list as a "matched triple" and randomly selected one school in each triple to treatment, one to main control, and one to supplementary control. Randomization was done in Stata using a random number generator.
