Traditional estimators of reliability such as coefficients alpha, theta, omega, and rho (maximal reliability) are prone to give radical underestimates of reliability for the tests common when testing educational achievement. These tests are often structured by widely deviating item difficulties. This is a typical pattern where the traditional…

This study aims at identifying the effect of multiple-choice test items' difficulty degree on the reliability coefficient and the standard error of measurement depending on the item response theory IRT. To achieve the objectives of the study, (WinGen3) software was used to generate the IRT parameters (difficulty, discrimination, guessing) for four…

The Content Proximity Project was designed to improve the content validity of the MAP® Growth™ assessments while retaining the ability for the test to adapt off-grade and meet students wherever they are in their learning. Two main features of the project were the development of an enhanced item selection algorithm, and a spring pilot study…

Achievement tests are among the most widely used data collection tools to measure the knowledge and skill levels of individuals. For this reason, the existence of valid and reliable achievement tests that can perfectly reveal the competencies that a person should have in any discipline is of great importance. The purpose of this research is to…

Tests are designed as an integral part of the teaching process, necessarily including stakeholders from the onset of preparations to grade allocation, the administration of the test, and the interpretation of the results. The process commences with selecting content to evaluate, deciding upon the skills to be tested, and to meet course objectives…

The first batch of graduates in the country under the K-12 curriculum graduated in 2018. Thus, a call for an evaluation of students' acquired competency is essential. That's why, there is a need for the construction of assessment tools. In this study, a valid, reliable, and item quality achievement test in General Mathematics was developed. Eight…

Questionnaire scales that are mixed-worded, i.e. include both positively and negatively worded items, often suffer from issues like low reliability and more complex latent structures than intended. Part of the problem might be that some responders fail to respond consistently to the mixed-worded items. We investigated the prevalence and impact of…

Literature review shows that the development process of an achievement test is mainly investigated in dissertations. Moreover, preparing a form that will shed light on developing an achievement test is expected to guide those who will administer the test. In this line, the current study aims to create an "Achievement Test Development Process…

This technical report documents the processes and procedures employed by NWEA® to build and support the English MAP® Reading Fluency™ assessments administered during the 2020-2021 school year. It is written for measurement professionals and administrators to help evaluate the quality of MAP Reading Fluency. The seven sections of this report: (1)…

To ensure that student academic growth in a subject area is accurately captured, it is imperative that the underlying scale remains stable over time. As item parameter stability constitutes one of the factors that affects scale stability, NWEA® periodically conducts studies to check for the stability of the item parameter estimates for MAP®…

An achievement test was prepared to determine students' caricature reading skills. In the first draft of the achievement test, 32 test items and four choices were prepared for each question. The item analysis of the data obtained from the pre-application was made and the internal consistency coefficient (KR-20) was calculated as 0.67 for the…

The aim of the study is to develop an achievement test consisting of the questions in verbal intelligence games whose validity and reliability have been ensured and which are in accordance with the learning outcomes of the states of substance and knowing the properties of substance via the five senses taking place in the unit "Let's Know…

This research aimed to investigate animation-based achievement tests according to the item format, psychometric features, students' performance, and gender. The study sample consisted of 52 fifth-grade students in Samsun/Turkey in 2017-2018. Measures of the research were open-ended (OE), animation-based open-ended (AOE), multiple-choice (MC), and…

This study determined the psychometric properties of the Economics Achievement Test (EAT) using Item Response Theory (IRT). Two popular IRT models namely, one-parameter logistics (1PL) and two-parameter logistics (2PL) models were utilized. The researcher adopted instrumentation research design. Four research questions and two hypotheses were…

The Computer-based Orthographic Processing Assessment (COPA) is a newly developed assessment to measure orthographic processing skills, including rapid perception, access, differentiation, correction, and arrangement. In this study, cognitive diagnostic models were used to test if the dimensionality of the COPA conforms to theoretical expectation,…
