The Kaufman Test of Educational Achievement, 3rd edition (KTEA-3) is a popular battery for the assessment of students' academic skills. Its manual includes a series of confirmatory factor analyses to support construct validity. Its five-factor model did not include all available subtests in the battery and required covarying residuals between…

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…

In the current study, we aimed to develop a reliable and valid scale to address individual cognitive load types. Existing scale development studies involved limited number of items without adequate convergent, discriminant and criterion validity checks. Through a multistep correlational study, we proposed a three-factor scale with 13 items to…

The Student Background survey administered along with achievement tests in studies of the International Association for the Evaluation of Educational Achievement includes scales of student motivation, competence, and attitudes toward mathematics and science. The scales consist of positively- and negatively keyed items. The current research…

The study was conducted with 3,385 participants who took an English language proficiency test as a partial requirement for entering a PhD program in different fields of education. This test has three sections which are grammar, vocabulary and reading comprehension. To determine the construct validity of the test, a series of analyses were done.…

English language learners (ELLs) constitute one of the fastest growing subpopulations of students in the United States. It is important to determine whether the assessments used by states in determining students' proficiencies are valid and fair for ELLs. This study focused on several standards-based assessments in mathematics and science…

The construct validity of a supplemental scoring system for the Kaufman Assessment Battery for Children (K-ABC) was evaluated with 146 referred school-age children (aged 6 to 12.5 years) and the K-ABC normative sample. Results support the construct validity of only part of the scoring model. (SLD)

This study examined the construct validity of the KeyMath-Revised by testing the factorial model proposed by the test author. Results failed to confirm the proposed factorial model and suggested that the KeyMath-Revised assesses two domains that are difficult to interpret, rather than the three proposed by the test author.
