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.

To develop Pathway to Proficiency reports for Tennessee Star Reading Enterprise and Star Math Enterprise schools, we linked our scaled scores with the scaled scores from Tennessee's achievement test. This technical report details the statistical method behind the process of linking Tennessee's state test (TNReady) and Star Reading and Star Math scaled scores.

From the abstract: "The purpose of the study was twofold. The first purpose of the study was to determine if a correlation existed between the Standardized Test for the Assessment of Reading (STAR), created and distributed by Renaissance, and the Tennessee Comprehensive Assessment Program (TCAP) Achievement Test in Math and Reading for grade 3, grade 4, and grade 5. The second purpose of this study was to evaluate the relationship between the percentile category of the STAR test and the TCAP test. The factor variable, identified as the percentile category, included three levels: Urgent Intervention, Intervention, and At/Beyond Benchmark. The dependent variable was the TCAP score. The study included 3rd-grade, 4th-grade, and 5th-grade students during the 2016-2017 school year who had taken the STAR reading and STAR math assessments and had taken the TCAP reading and TCAP math assessment.Based on the findings of this study, a strong correlational relationship does exist between the STAR and TCAP assessments. Overall, the strong correlation between the STAR and the TCAP were consistent across Math and Reading in 3rd, 4th, and 5th grades. Since the ANOVA was significant, a post hoc multiple comparisons was conducted to evaluate pairwise difference among the means of the three groups. Overall, the At/Beyond Benchmark group was significantly higher than both the Urgent Intervention group and the Intervention group in Math and Reading for 3rd grade, 4th grade, and 5th grade. There was not a significant difference between the Urgent Intervention group and the Intervention group, the exception was 5th grade math." Citation: Sampson, B. (2018).

From the abstract: "The impetus for this study was to determine how Accelerated Reader influences the reading attitudes of fourth grade students of varied reading proficiencies who had been exposed to Accelerated Reader since kindergarten. Interested in students' attitudes and motivation toward reading, I examined fourth grade students' reading motivation among two award winning Blue Ribbon Schools in East Tennessee, one of which used Accelerated Reader as the pathway to literacy success while the other did not. Comparisons between the two schools were made in order to determine if there were differences in students' attitudes and motivation toward reading. This explanatory mixed methods study incorporated both quantitative and qualitative research methods. Data were generated through the Motivation to Read Profile-Revised survey and semistructured individual interviews. The quantitative results indicated that in relation to the overall MRP-R survey, there were no statistically significant differences between students who participate in Accelerated Reader and those who do not. There was not a statistical difference between the AR school and the school without AR regarding survey questions aligned to selfconcept. There was a significant difference found on the subcategory of value of reading among the two schools. The AR school produced higher scores on the survey questions aligned to value of reading.After the initial quantitative analysis was conducted, interview questions were formulated to delve more deeply into these findings. When incorporating Explanatory Sequential Models, the qualitative phase follows the quantitative analysis to more fully elucidate the narrative behind the numbers generated. The results obtained from these differing methods of research produced findings that were sometimes contradictory. These contradictions were discovered through the semi-structured interview questions that were intended to further explicate the quantitative findings."Citation: Boone, L. S. (2017).

From the abstract: "The purpose of this study was to compare both rates of reading achievement growth and predictive power of two widely-used assessments representing two different approaches to measurement - a computer adaptive assessment called Star Reading and a curriculum based measurement called AIMSweb. A total of 117 students from a school district in Tennessee were included in the sample. Data collection spanned two school years, and included students who were progress monitored (taking a minimum of 4 tests per year) in grades 1 through 4 in one year, and in grades 2 through 5 the subsequent year. Across the two years, interventions for both groups of students were consistent. The results of this study indicate that both measures were able to detect incremental change, and provide further support that both computer adaptive measures such as Star Reading and CBMs such as AIMSweb R-CBM are acceptable for progress monitoring. Of the two measures, only Star Reading achieved a significant correlation with the state reading assessment."Citation: Shapiro, E. S., & Gibbs, D. P. (2014).

From the abstract: "The purpose of this study was to determine if a difference existed between TCAP scores of students who used the Accelerated Reader (AR) program and students who used Sustained Silent Reading strategy (SSR) as measured by the Tennessee Comprehensive Assessment Program (TCAP). The variables of grade level (6th, 7th, and 8th), gender, and socioeconomic status (free- or reduced- price meals program) were considered. The population consisted of 108 6th graders who attended a Cocke County school or a McMinn County school in Tennessee. Data were obtained from the TCAP for 3 consecutive years beginning in 2004-2005 for students who completed the tests all 3 years. A t test for independent samples and analysis of variance (ANOVA) were used to determine if there was a difference on associations and interactions between variables.The researcher's investigation of the reading achievement of students who used Accelerated Reader and those who used Sustained Silent Reading should assist educators in planning for supplemental reading instruction. The information gathered from this research might be beneficial to other school systems when determining which method of reading instruction to use to increase students' reading achievement.The findings indicated the students who used the Accelerated Reader program had an increase in reading-language arts scale scores for 3 consecutive years. The findings of this study also revealed that gender had no significance on student achievement for 6th graders. The findings did indicate a significant interaction between gender and type of program used during 7th and 8th grades. Females who used the Accelerated Reader program outscored males who used the program. The findings of this study also determined that socioeconomic status had no association with TCAP scores during the 6th, 7th, or 8th grades." AUTHOR: J. Brown.

DETAILS: Location: KY, AZ, CA, MS, SC, AR, CO, GA, NV, NM, and TN; Design: Independent, correlational; Sample: 47 local model literacy initiative programs; Measure: Star Reading; Duration: 1 school year. RESULTS: During the 2005-2006 school year, Save the Children supported several local programs in its model literacy initiative. Twenty of the sites operated for the first time that year, while 15 began operation in the spring of the 2004-2005 school year, and the remaining 12 began during the 2003-2004 school year. Services at the sites included delivery of integrated in-school, after-school, and summer-school literacy activities including using Accelerated Reader. This report describes implementation of the literacy model at each site, the characteristics of participating children, and the learning results achieved during 2005-06. During the 2005-06 school year, the proportion of participants reading at a level appropriate for their grade level or above increased. On the initial Star Reading test, 21.8% of students were at grade level or higher--a normal curve equivalent (NCE) score of 50 or more. The final Star Reading test showed that 27.3% were reading at grade level. The average pre-post change in Star Reading scores was 3.9 NCEs, which was statistically significant.

DETAILS: Location: Memphis, Tennessee; Design: Independent, experimental, peer-reviewed; Sample: 1,665 students and 76 teachers at 11 elementary schools; Measures: Star Early Literacy, Star Reading; Duration: 1 school year. RESULTS: In this study, teachers at urban elementary schools were randomly assigned to use or not use Accelerated Reader. Star Early Literacy and Star Reading results showed significant gains and moderate to large effect sizes in grades K-2 and small to moderate effect sizes in grades 3-6. Eighty-three percent of the students in grades 3-6 were eligible for free or reduced-price lunch. Students with learning disabilities benefited most in classrooms with high-implementation of Accelerated Reader compared to those in low- or no-implementation classrooms.
