Accelerated Reader is a progress-monitoring system that provides feedback on the comprehension of books and other materials that students have read. It also tracks student reading over time. Currently, more than 180,000 different Accelerated Reader quizzes have been developed and are in use. This report provides reliability and validity data for Accelerated Reader quizzes. The reliability analyses use a large database of nearly 1 million quiz records. Validity is established through correlations with scores from 24 standardized reading tests and through a study that confirms that the quizzes are effective at discriminating between instances of students having read the book versus not having read the book. The report also includes descriptions of the purpose and intended classroom use of Accelerated Reader, descriptions of the types of quizzes, and the processes for quiz development.

DETAILS: Location: Florida; Design: Independent, realibility and validity research; Sample: 1,077 students in Grade 6, 7, and 8; Measure: Star Reading, Scholastic Reading Inventory-Interactive, and Florida Comprehensive Assessment Test; Duration: 4 months.RESULTS: This peer-reviewed journal article from Bob Algozzine, Chuang Wang, and Anatoli Boukhtiarov at the University of North Carolina at Charlotte examined the extent to which an interim progress monitoring assessment in reading (Star Reading) could predict later performance on a high-stakes test (Florida Comprehensive Assessment Test). Star Reading was found to be a good predictor of FCAT. CITATION: Algozzine, B., Wang, C., & Boukhtiarov, A. (2011). A comparison of progress monitoring scores and end-of-grade achievement.

DETAILS: Location: Throughout the US; Design: Independent, peer-reviewed; Sample: 659,214 students in grades K-12 at 2,193 schools; Measure: Accelerated Reader data. RESULTS: This study provided further evidence of the positive relationship between amount of reading practice and reading ability. In addition to gathering Accelerated Reader data for the study sample, 13,000 schools were also surveyed for the project, and the ethnicity and socioeconomic status of these students were found to be generally similar to U.S. students as a whole. Consistent with other research in the field, the study found that students in the highest quartile practiced reading 3.4 to 4.1 times more than students in the lowest quartile. In addition, the top 5% of readers read 144 times more than bottom 5%. The data also suggested that, on average, amount of reading practice increases until 6th grade and then declines. Finally, it was observed that schools using Accelerated Reader for 4 or more years had a 64% higher level of reading practice compared to schools using Accelerated Reader for 1 year.

DETAILS: Design: Correlational; Sample: Data for 659,214 students in grades K-12. RESULTS: This study of reading is one of the largest ever conducted and collected reading performance data for 659,214 K-12 students. Key findings concluded students spend only seven minutes per day practicing reading, and reading practice declines markedly after 5th grade.
