Propensity score estimation plays a fundamental role in propensity score matching for reducing group selection bias in observational data. To increase the accuracy of propensity score estimation, the author developed a bootstrap propensity score. The commonly used propensity score matching methods: nearest neighbor matching, caliper matching, and…

The Success By 6® (SB6) initiative is designed to support early care and education centers in improving and sustaining quality in Pennsylvania's Keystone STARS Quality Rating and Improvement System (QRIS). The SB6 evaluation report examines implementation and outcomes. The findings have implications for SB6 continous quality improvement process…

Using detailed administrative data from Virginia, this paper examines how and why the community college pathway to a baccalaureate influences students' degree attainment and short-term labor market performance. We find that the community college pathway sharply reduces the likelihood of earning a bachelor's degree but does not have a significant…

Recently, the Smarter Balanced Assessment Consortium (Smarter Balanced) released a document that established initial performance levels and the associated threshold scale scores for the Smarter Balanced assessment. The report included estimated percentages of students expected to perform at each of the four performance levels, reported by grade…

The paper shows how to find the min and max extreme interval values for the exponential and triangular distributions from the min and max uniform extreme interval values. Tables are provided to show the min and max extreme interval values for the uniform, exponential, and triangular distributions for different probabilities and observation sizes.

Northwest Evaluation Association™ (NWEA™) is committed to providing partners with useful tools to help make inferences from the Measures of Academic Progress® (MAP®) interim assessment scores. One important tool is the concordance table between MAP and state summative assessments. Concordance tables have been used for decades to relate scores on…

This report describes the results of a REL Southeast study comparing student success in online credit recovery and general courses taken online compared to traditional face-to-face courses. Credit recovery occurs when a student fails a course and then retakes the same course to earn high school credit. This research question was motivated by the…

Co-rumination is a dyadic process between relationship partners that refers to excessively discussing problems, rehashing problems, speculating about problems, mutual encouragement of problem talk, and dwelling on negative affect. Although studies have addressed youths' "tendency" to co-ruminate, little is known about the nature of…

The grades K-2 Florida Center for Reading Research (FCRR) Reading Assessment (FRA) consists of computer-adaptive alphabetic and oral language screening tasks that provide a Probability of Literacy Success (PLS) linked to grade-level performance (i.e., the 40th percentile) on the word reading (in kindergarten) or reading comprehension (in grades…

Recently, Northwest Evaluation Association (NWEA) completed a study to connect the scale of the Minnesota Comprehensive Assessments (MCA) Testing Program used for Minnesota's mathematics and reading assessments with NWEA's RIT (Rasch Unit) scale. Information from the state assessments was used in a study to establish performance-level scores on…
