The continued accumulation of validity evidence for the intended uses of educational assessment scores is critical to ensure that inferences made using the scores are sound. To that end, the College Board has continued to collect college outcome data to evaluate the relationship between SAT® scores and college success. This report provides updated…

In this paper, we examine the validity and precision of two nonexperimental study designs (NXDs) that can be used in educational evaluation: the comparative interrupted time series (CITS) design and the difference-in-difference (DD) design. In a CITS design, program impacts are evaluated by looking at whether the treatment group deviates from its…

The 2013-2014 North Carolina Pre-Kindergarten (NC Pre-K) Evaluation study was designed to examine the longitudinal outcomes through kindergarten for children who attended the Pre-K program, along with comparisons to previous cohorts of program attendees. A sample of 561 children was included in the study, with data gathered at the beginning and…

The objectives of this research are to (a) compare the trend lines after some adjustments for level and scale only and determine if and how they differ; (b) describe the methodology of each assessment and identify similarities and differences; and (c) attempt to explain any observed differences based on comparable subsets or on special analysis.…

In this technical report, we provide the results of a series of studies on the technical adequacy of the early reading measures available on the easyCBM[R] assessment system. The results from the two-level hierarchical linear growth model analyses suggest that the reliability of the slope estimates for the easyCBM[R] reading measures are strong,…

In this technical report, we provide reliability and validity evidence for the easyCBM[R] Reading measures for grade 2 (word and passage reading fluency and multiple choice reading comprehension). Evidence for reliability includes internal consistency and item invariance. Evidence for validity includes concurrent, predictive, and construct…

In this series of studies, we investigated the technical adequacy of three curriculum-based measures used as benchmarks and for monitoring progress in three critical reading- related skills: fluency, reading comprehension, and vocabulary. In particular, we examined the following easyCBM measurement across grades 3-7 at fall, winter, and spring…

Key findings of a pilot study of the Alaska Instructional Diagnostic System (AIDS) are summarized. The AIDS pilot test served to verify the appropriateness of the skills survey as well as the validity and reliability of the items. The AIDS testing system includes three components: (1) upper level skills surveys (grades 3-8); (2) lower level skill…

This study investigated the relationship between the scales used for the NMSBA assessments and the RIT scales used to report performance on Northwest Evaluation Association tests. The study estimated the changes in reading and mathematics RIT score equivalents for the NMSBA performance levels in those subjects. Test records for more than 17,000…

Recently NWEA completed a project to connect the scale of the WKCE with NWEA's RIT scale. Six Wisconsin school systems participated in the study, using test information from a group of over 1,500 students enrolled in fourth, eighth, and tenth grade who took both the WKCE and NWEA tests in the fall of 2003. Information from these tests was used in…

This technical manual provides all major existing information about the technical characteristics of the Kentucky Instructional Results Information System (KIRIS). The assessment component of the Kentucky Education Reform Act Accountability System was in use between 1991-92 and 1993-94 and was referred to as Cycle One. Two sets of test…

This technical manual provides information about the technical characteristics of the Kentucky Instructional Results Information System (KIRIS), the assessment component of the Kentucky Education Reform Act Accountability System. The time period covered is Accountability Cycle 2, which spanned the school years 1992-93 through 1995-96. Sections of…

Each year, Montana students participate in testing as part of the state's assessment program. This past spring, students in grades 4, 8, and 10 took Montana Comprehensive Assessment System (MontCAS) tests in reading and mathematics. These tests serve as an important measure of student achievement for the state's accountability system. Results from…

Each year, Nevada students in grades 3, 4, 5, and 7 participate in testing as part of the Nevada assessment program. Students in grades 3 and 5 take the Nevada Criterion Referenced Assessment (Nevada CRT) while students in grades 4 and 7 take the Iowa Test of Basic Skills (ITBS). These tests serve as an important measure of student achievement for…

Each year, Pennsylvania students participate in testing as part of the Pennsylvania assessment program. Students in grades 5, 8, and 11 take tests in reading and math while those in grades 6, 9 and 11 are assessed in writing. These tests serve as an important measure of student achievement for the state's accountability system. Results from these…
