When analyzing treatment effects on test scores, researchers face many choices and competing guidance for scoring tests and modeling results. This study examines the impact of scoring choices through simulation and an empirical application. Results show that estimates from multiple methods applied to the same data will vary because two-step models…

This study examines the relationship of the underlying skills of printing, spelling and vocabulary choices as they influence the quality of writing at the end of Grade 2. Four classes of Grade 2 (N = 85) writing in response to an expository prompt were scored holistically on a trait based rubric, then scored for spelling accuracy and…

The factor structure of the Phonological Awareness Literacy Screening for Grades 1 through 3 (PALS 1-3), a widely used early literacy screener in the Commonwealth of Virginia, was investigated using a large sample of public-school second-grade students (n = 14,993). Three alternative factor models (i.e., a one-factor, two-correlated factors, and a…

The present study seeks to evaluate a hybrid model of identification that incorporates response to instruction and intervention (RTI) as one of the key symptoms of reading disability. The 1-year stability of alternative operational definitions of reading disability was examined in a large-scale sample of students who were followed longitudinally…

A mixed methodological approach was used to examine the effect of a cross-age tutoring writing program among second- and fourth-grade students in a rural elementary school in Delaware. Pre-test and post-test writing prompts were administered and evaluated using the 6+1 traits writing assessment rubric. Students were assessed qualitatively through…
