This paper reports an investigation into the psychometric properties of the COR-Advantage1.5 (COR-Adv1.5) assessment tool, a criterion-referenced observation-based instrument designed to assess the developmental abilities of children from birth through kindergarten. Using data from 8534 children participating in a state-funded preschool program…

Curriculum-based measures (CBMs) such as Word Identification Fluency promote student achievement, but because they are timed and administered frequently, they are prone to variation in student response styles. To study the impact of WIF response styles, we created and examined the validity of a novel response style measure and examined the degree…

Student engagement appears to be associated with high-quality learning outcomes. Thus, it is important to measure whether students are engaging effectively in class. This article describes the development and validation of a measure of student engagement named the Student Course Engagement Scale (SCES). Exploratory and confirmatory analyses were…

We provide evidence of validity for a newly developed diagnostic competence model of operation sense, by both (a) describing the theoretically substantiated development of the competence model in close association with its use within a large-scale formative assessment and (b) providing empirical evidence for the theoretically described cognitive…

The literature contains a variety of assessment tools for measuring the skills of individuals with autism or other developmental delays, but most lack adequate empirical evidence supporting their reliability and validity. The current pilot study sought to examine the reliability of scores obtained from the Assessment of Basic Language and Learning…

Content validation is a crucial, but often neglected, component of good test development. In the present study, content validity evidence was collected to determine the degree to which elements (e.g., grammatical structures, items, picture responses, administration, and scoring instructions) of the Comprehension of Written Grammar (CWG) test are…

The Kaufman Test of Educational Achievement, Third Edition (KTEA-3) is a revised and updated comprehensive academic achievement test (Kaufman & Kaufman, 2014). Authored by Drs.

Psychometric properties of the Phonological Awareness Literacy Screening for Preschool (PALS-PreK) instrument were investigated in a sample of 4,518 children. PALS-PreK figures prominently in state and federal early literacy programs as an assessment of emergent literacy skills in preschool-aged children. Exploratory Factor Analysis, Confirmatory…
