Summative assessments measure students' mastery of grade-level academic standards and skills in specific content areas after learning. State summative assessment systems provide students and families, school and district leaders, and state policymakers with valuable data to help understand student progress and school quality. This Policy Guide…

Research evidence concerning the effects of adaptive teaching and individualized learning remain relatively inconclusive, while there is obviously a need for better understanding how K-12 formal education may be more successful in addressing students' personal needs and interests, accounting for their diverse abilities with the main goal of…

While many educators expect the Common Core State Standards (CCSS) to be more rigorous than previous state standards, some wonder if the transition to CCSS and to a Common Core aligned MAP test will have an impact on their students' RIT scores or the NWEA norms. MAP assessments use a proprietary scale known as the RIT (Rasch unit) scale to measure…

Discusses the potential positive and negative effects computer-based testing could have on validity, reviews the literature on validation perspectives in computer-based testing, and suggests ways to evaluate the contributions of computer-based testing to more valid measurement practices. (SLD)

Computer-based testing can provide flexibility, instant feedback, and individualized assessment. The most straightforward use of computer testing is for traditional performance and accountability functions as evidenced in Georgia, North Carolina, Oregon, Pennsylvania, and Virginia. Other states are using computer-based testing for diagnostic and…

Northwest Evaluation Association in Portland, Oregon, consults with state and local educators on assessment issues. Describes several approaches in place at school districts that are using some combination of computer-based tests to measure student growth. The computerized adaptive test adjusts items based on a student's answer in "real…

This paper contains the technical specifications, schematic diagrams, and program printout for a computer software package for the development and administration of diagnostic tests. The second version of the Diagnostic Testing Package DX consists of a PASCAL-based set of modules located in two main programs: (1) EDITTEST creates, modifies, and…

The Northwest Evaluation Association helped an Indiana school district develop a computerized adaptive testing system that was aligned with its curriculum and geared toward measuring individual student growth. Now the district can obtain such information from semester to semester and year to year, get immediate results, and test students on…

Presents a conceptual framework of educational diagnosis based on formative evaluation. Describes a computer-based diagnostic system that maximizes the coherence and effectiveness of obtained information by generating a structural diagnosis of the nature of student errors and a causal diagnosis related to teaching methods. Contains 64 references.…

Computer adaptive testing is the study of scoring tests and questions based on assumptions concerning the mathematical relationship between examinees' ability and the examinees' responses. Adaptive student tests, which are based on item response theory (IRT), have many advantages over conventional tests. We use the least square method, a…

This document updates "Accommodations: Assisting Students with Disabilities. A Guide for Educators," published by the Florida Department of Education (FDOE) in 2003. This document is written to assist school district personnel and parents when making decisions about the use of accommodations by students with disabilities in instructional…

This paper presents an explanation of the program design of the three separate Pascal-language programs which comprise UCLA's Diagnostic Testing Package "DX." The three parts of the DX test package are three closely interrelated programs--Editest, Runtest, and Summary. Editest serves the following functions: (1) the creation of a…

The use of computers to build diagnostic inferences is presented in two contexts: (1) closed world, exemplified by the space shuttle launch monitoring system; and (2) open world, represented by computerized diagnostic testing of reading comprehension. The analysis shows that the closed world provides a substantially cleaner environment within…

This paper discusses the rationale for enhancing the current National Assessment of Educational Progress (NAEP) design by adding a capacity for adaptive testing. Items are tailored to the achievement level of the student in adaptive testing. The report describes a 1993 Ohio field trail of two-stage assessment carried out by the National Opinion…

Limitations seen in traditional educational procedures are discussed, and three new directions are suggested as being important emphases for testing. A new perception of measurement in which children have positions along particular concept dimensions or "lines" is discussed in terms of traditional testing notions including variables, item banks…
