Blue Valley, the fourth largest school district in Kansas, covers 91 square miles. More than 20,000 K-12 students attend its 34 schools (five high schools, nine middle schools, and 20 elementary schools). Blue Valley began using MAP® Growth™ in 2005 to track students' academic growth over time and independently of grade level. In 2010 the district…

The six primary papers in this issue of "Assessment in Education" emphasise a single primary point: the concept of validity is a complex one. Essentially, validity is a collective noun. That is, just as a group of players may be called a team and a group of geese a flock, so too does validity represent a variety of processes and…

Despite the often-negative discussion about testing in schools, assessments are a necessary and useful tool in the teaching and learning process. This is especially true when it comes to diagnostic and formative assessments, which give teachers real-time direction for what students need to learn to master course content. It is this space where the…

The purpose of this embedded-descriptive single-case study was to provide insight into one prekindergarten school's efforts to build teacher capacity in foundational skills. An embedded-descriptive single-case study was a suitable design for the study because the researcher could not manipulate the school's efforts; the setting was contemporary…

Research has found that the "a"-stratified item selection strategy (STR) for computerized adaptive tests (CATs) may lead to insufficient use of high a items at later stages of the tests and thus to reduced measurement precision. A refined approach, unequal item selection across strata (USTR), effectively improves test precision over the…

A few years ago, Marnie O. Malone and her team at Elmira City Schools found themselves facing a challenge that's all too common: How can we best support students who we know aren't likely to meet grade-level standards? To find an answer, they looked to the MAP® Suite of assessments from NWEA®. This brief case study describes how Malone and her…

The purpose of this embedded-descriptive single-case study was to inform prekindergarten principals of an instructional leader's efforts to build teacher capacity in foundational skills of executive function, fine motor integration skills, and associated challenges of laterality of hand and eye dominance. Despite Texas Education Agency's (TEA)…

The American Chemical Society-Examinations Institute (ACS-EI) released the first ACS Foundations of Inorganic Chemistry Examination in 2016 to better address the two generalized types of inorganic chemistry courses (i.e., at the foundation or second/third-year level and the indepth or third/fourth-year level). The ACS Inorganic Chemistry Exam that…

Background: This study investigated the psychometric properties of the recently developed Qiyas for L1 Arabic language test using a Rasch measurement framework. Methods: Responses from 271 examinees were analyzed in this study. The test is hypothesized to involve one dominant factor that assesses four skills: reading comprehension, rhetorical…

Recently a novel instrument -- the Core Academic Language Instrument (CALS-I) -- aimed at testing a constellation of school-relevant English language skills was developed and validated for use in the United States (Uccelli, Barr, Dobbs, Galloway, Meneses and Sánchez, 2015. Core Academic Language Skills: An expanded operational construct and a…

Despite the popularity of the TOEIC in the Korean society for over 30 years, few studies have investigated the understanding and usage of TOEIC scores in the Korean context. This research gap needs to be filled to provide test users with useful information in the Korean context. Using an argument-based approach to validation, this study…

As the number of candidates who repeat English language proficiency tests more than once to meet a certain cutscore (e.g., for university admission) or to demonstrate progress (e.g., after instruction) continues to increase dramatically, there is a need for more research on the attributes and test performance of test repeaters. This article…

How we choose to use a term depends on what we want to do with it. If "validity" is to be used to support a score interpretation, validation would require an analysis of the plausibility of that interpretation. If validity is to be used to support score uses, validation would require an analysis of the appropriateness of the proposed…

Naomi Gafni, director of Research and Development, National Institute for Testing and Evaluation, Jerusalem, Israel, has devoted a substantial part of her career to the development of admissions tests and other educational tests and to the investigation of their validity. As such she is keenly aware of the complexities involved in this process.…

Inquiry-oriented teaching is a specific form of active learning gaining popularity in teaching communities. The goal of inquiry-oriented classes is to help students in gaining a conceptual understanding of the material. My research focus is to gauge students' performance and conceptual understanding in inquiry-oriented linear algebra classes. This…
