The purpose of document is to provide readers with the coding protocol that authors used to code 76 meta-analyses focused on students with or at-risk of disabilities. All of the included meta-analyses provided a summary statistic related to at least one of the High Leverage Practices (HLPs; McLeskey et al., 2017). ). The purpose of the systematic review of meta-analyses was to provide an initial investigation of the evidence supporting the effectiveness of the HLPs for students with, or at-risk for, a disability. This code book contains variable names, code options, and code definitions related to basic study information (i.e., authors, year of publication, journal), the details of each study, participant demographics, HLPs included in each study, and summary statistics. The mean interrater reliability across all codes using this protocol was 88% (range across categories = 84%–97%).
