The 2018 Nebraska Student-Centered Assessment System (NSCAS) Summative technical report documents the processes and procedures implemented to support the Spring 2018 NSCAS Summative English Language Arts (ELA), Mathematics, and Science assessments by NWEA under the supervision of the Nebraska Department of Education (NDE). The technical report…

Differential granting of extra-examination time (EET) is commonly based on learning disabilities (LD) status: EET is granted to LD examinees and is denied to nondisabled examinees. We argue that LD serves as a proxy for the extent to which time limitation affects the examinee's test score (e). Hence, the validity of the LD-based EET granting…

Kindergarten entry assessments (KEAs) have increasingly been incorporated into state education policies over the past 5 years, with much of this interest stemming from Race to the Top--Early Learning Challenge (RTT-ELC) awards, Enhanced Assessment Grants, and nationwide efforts to develop common K-12 state learning standards. Drawing on…

These guidelines describe considerations relevant to the assessment of test takers in or across countries or regions that are linguistically or culturally diverse. The guidelines were developed by a committee of experts to help inform test developers, psychometricians, test users, and test administrators about fairness issues in support of the…

The purpose of this report is to describe the technical qualities of the 2018-2019 operational administration of the English language arts/literacy (ELA/L) and mathematics summative assessments in grades 3 through 8 and high school. The ELA/L assessments focus on reading and comprehending a range of sufficiently complex texts independently and…

The purpose of this report is to describe the technical qualities of the 2018-2019 operational administration of the English language arts/literacy (ELA/L) and mathematics assessments in grades 3 through 8 and high school. New Meridian, in coordination with multiple states and vendors, developed an alternate form of the summative assessment to…

Including students with special educational needs in learning (SEN-L) is a challenge for large-scale assessments. In order to draw inferences with respect to students with SEN-L and to compare their scores to students in general education, one needs to assure that the measurement model is reliable and that the same construct is measured for…

This chapter addresses the psychometric challenges in assessing English language learners (ELLs) and students with disabilities (SWDs). The first section addresses some general considerations in the assessment of ELLs and SWDs, including the prevalence of ELLs and SWDs in the student population, federal and state legislation that requires the…

Standardizing aspects of assessments has long been recognized as a tactic to help make evaluations of examinees fair. It reduces variation in irrelevant aspects of testing procedures that could advantage some examinees and disadvantage others. However, recent attention to making assessment accessible to a more diverse population of students…

Extended time is one of the most common testing accommodations provided to students with disabilities. It is also controversial; critics of extended time accommodations argue that extended time is used too readily, without concern for how it changes the skills measured by tests, leading to scores that cannot be compared fairly with those of other…

This bibliography provides abstracts of 28 recent (most were published since 1993) books, journal articles, and other documents concerned with testing accommodations for students with disabilities. The emphasis was on studies examining the effects of testing accommodations on the technical integrity of assessment measures. However, the…
