This study examined psychometric properties of the Motor Skills Rating Scale (MSRS), a questionnaire designed for classroom teachers of children in early elementary school. Items were developed with the guidance of two occupational therapists, and factor structure was examined with an exploratory factor analysis (EFA). The resulting model showed…

The validity of the Student-Teacher Relationship Scale (STRS) was examined in a national sample of 863 Norwegian schoolchildren in grades 1-7 (aged 6-13). The original factor structure of the STRS was tested by confirmatory factor analysis (CFA). The CFA results did not support the original three-factor structure of the STRS. Subsequent CFA of the…

This article presents results from two studies that included ethnically and socioeconomically diverse samples totaling 4,462 children in kindergarten through third grade. Each study examined the psychometric properties of a web-based, self-administered battery of assessments of social-emotional comprehension called "SELweb." Assessment…

The purpose of this study was to investigate the reliability and validity of a newly developed survey instrument, the "Primary Practices Questionnaire" ("PPQ"), designed to measure first, second, and third grade teachers' perceived use of developmentally appropriate practices.

This study examined the changing role and longitudinal predictive validity of curriculum-embedded progress-monitoring measures (CEMs ) for kindergarten students receiving Tier 2 intervention and identified as at risk of developing reading difficulties. Multiple measures were examined to determine whether they could predict comprehensive latent…

This study evaluated the validity of a new scale for assessing children's reading fluency skill called the Comprehensive Oral Reading Fluency Scale (CORFS). The CORFS consists of two subscales that capture key elements of the Kuhn, Schwanenflugel, and Meisinger (2010) definition of reading fluency: reading expression, reading rate, and accuracy.…

The Brigance Comprehensive Inventory of Basic Skills-II (CIBS-II) is the newest version of a long-standing instrument that is useful for identifying student achievement, identifying and monitoring academic strengths and weaknesses, obtaining data to support referrals, and reporting progress for individual educational plans.
