Cobblestone Applied Research & Evaluation, Inc. launched a quasi-experimental design (QED) study to investigate the impact of the HMH Into Reading Texas curriculum on student reading test scores. The design entailed comparing student scores on the State of Texas Assessment of Academic Readiness (STAAR) from 100 treatment schools (Into Reading Texas users) to 100 well-matched control schools (non-Into Reading Texas users) across the state of Texas. The study was designed to meet Tier 2 (Moderate Evidence) of the Every Student Succeeds Act (ESSA). To ensure the safety and welfare of students, teachers, and all school personnel in the wake of COVID-19, the state of Texas canceled 2020 STAAR testing. As a result, the present QED study was suspended. HMH is currently in the process of relaunching the study. To learn more about the study design and baseline data, please download the full report.
