Reading outcomes at a national level have remained stagnant for more than two decades. One reason why is that the field has struggled with how to address poor reading comprehension when reading words is not the problem. Another is that limited insight into the causes of poor comprehension performance is offered by traditional reading comprehension…

Student growth percentiles (SGPs) are currently used by several states and school districts to provide information about individual students as well as to evaluate teachers, schools, and school districts. For SGPs to be defensible for these purposes, they should be reliable. In this study, we examine the amount of systematic and random error in…

We present two types of validity evidence to support inferences and decisions about use of easyCBMs in relation to state testing programs. The first type involves the use of Benchmarks in reading to use in making predictions of performance on the Smarter Balanced (SB) test. These predictions can be made both well in advance (several months) or…

Reclassification is a crucial outcome for English learner (EL) students' academic progress. Though ELs spend a large portion of their academic time with general education teachers, we know little about the role general education teachers play in developing ELs' English language proficiency. Drawing from a longitudinal administrative dataset from…

This study examined how attaining English proficiency and being reclassified as fluent English proficient affected achievement in English language arts and math in the first year after student reclassification in grades 3-8 in New Mexico. State policy in New Mexico bases student reclassification decisions on whether students attain a minimum…

This Study Snapshot highlights key findings from a study that examined how attaining English proficiency and being reclassified as fluent English proficient affected achievement in English language arts and math in the first year after student reclassification in grades 3-8 in New Mexico. New Mexico established a state-level policy that requires…

The "Effects of Reclassifying English Learner Students on Student Achievement in New Mexico" study examined being reclassified as fluent English proficient and achievement in English language arts and math in the first year after student reclassification. The study focused on achievement among English learner students in 2014/15-2018/19…

In achievement testing we assume that students will demonstrate their maximum performance as they encounter test items. Sometimes, however, student performance can decline during a test event, which implies that the test score does not represent maximum performance. This study describes a method for identifying significant performance decline and…

Using student-level longitudinal data from one large urban school district, I examine Long-term English Learners' (LTELs) characteristics and their linguistic and academic performance in comparison to on-track English learners and initially fluent students. I also investigate what factors are related to their becoming LTELs. This study focuses on…

Student assessment nonparticipation (or opt out) has increased substantially in K-12 schools in states across the country. This increase in opt out has the potential to impact achievement and growth (or value-added) measures used for educator and institutional accountability. In this simulation study, we investigated the extent to which…

The development of academic English proficiency and the time it takes to reclassify to fluent English proficient status are key issues in English learner (EL) policy. This article develops a shared random effects model (SREM) to estimate English proficiency development and time to reclassification simultaneously, treating student-specific random…

In response to a request for additional analyses, in particular reporting confidence intervals around the results, we re-analyzed the data from prior studies. This supplementary report presents the results of the additional analyses addressing classification accuracy, reliability, and criterion-related validity evidence. For ease of reference, we…

With the rapid growth in the number of English learner students served by schools in the United States, educators are increasingly concerned with how these students progress toward proficiency in English. The large and diverse English learner student population in New York City public schools, where more than 41 percent of students speak a…

Federal regulations indicate that the achievement gap must be closed between subgroups, including the gap between special education and non-special education students. We explored the ways in which achievement trends are influenced by three methods of reporting (cross-sectional, cohort-static, and cohort-dynamic). We also investigated (a) the ways…
