© 2025 Vista Higher Learning Vista’s Bridges: A Study of Reading Growth in MLs 8 As shown, both groups completed iReady Reading Skills pretests and posttests, allowing researchers to measure the impact of the Bridges instructional program compared with traditional classroom practice. ML students in classes receiving instruction that included Bridges achieved substantial levels of reading skill growth exceeding typical levels of growth for ML students, and at levels similar to their non-ML peers in grades 6, 7, and 8. Se ng The study was conducted in a district serving a diverse population of multilingual learners in grades 6–8. The district includes both urban and rural schools, and includes a wide range of student language backgrounds and socioeconomic levels. The Bridges to Literature and Content program was implemented in middle school classrooms as part of regular English language development and literacy instruction. Teachers participated in training sessions on using Bridges materials and instructional routines. Instruction was delivered during the 2024–2025 academic year under normal classroom conditions, without additional interventions or staffing support. Timeline The study occurred over the 2024–2025 school year. The district administered the iReady Reading Skills assessment at the beginning and end of the school year to all students. The iReady assessment is widely used nationally and has high levels of reliability and validity. The fall 2024 student scores for the assessment served as the pretest for the study; the spring 2025 student scores for the assessment served as the posttest for the study. In the fall of 2024, the district provided SEG Measurement with a data file that included the fall 2024 iReady assessment results for all students in the district in grades 6–8. The district also provided a listing for the classes in the treatment group using Bridges. In the spring of 2025, the district provided a similar data file containing the spring 2025 iReady assessment results. How Reading Growth Was Measured The iReady Reading Skills assessment, published by Curriculum Associates, was used as the measure of English reading skills. The (single form) reliability for the iReady Reading assessment in the middle school band is at or above .90. The test-retest reliability is reported in the mid-.80s to high-.80s. The iReady Reading assessment demonstrates strong validity. Curriculum Associates describes the test as “grounded in research, informed by experts, and proven to work,”
