In 2023, a group of district and school leaders and other education constituents convened by the Delaware Department of Education raised questions about the growth metric in the state's accountability system. They wondered whether the state's growth model was too highly related to achievement and, therefore, not rewarding schools for helping…

Federal law requires that state accountability systems include "another academic indicator" for elementary and middle schools in addition to academic achievement. Nearly all states use a measure of student longitudinal growth as their other academic indicator. But how should states decide which growth model to use? The Center for…

The Colorado Growth Model (CGM) was developed jointly by the Colorado Department of Education (CDE), the Technical Advisory Panel for Longitudinal Growth (TAP), and the National Center for the Improvement of Educational Assessment (NCIEA). Its development was required by state statute (SB09-163) and assigned to the Technical Advisory Panel. The…

With the shift from No Child Left Behind (NCLB) to Every Student Succeeds Act (ESSA), accountability models are being changed. Given the past 15 years of reporting on student subgroups and 10 years using various growth models, accountability systems can now be better informed. In this study, we analyze identification and services of students with…

The purpose of this report is to investigate the feasibility of constructing a school-level measure of students' academic growth from kindergarten to grade 3, and to assess the validity and precision of that measure. The study measured schoolwide student growth for reading and math using student growth percentiles based on Maryland's 2014/15…

When the 2017 National Assessment of Educational Progress was released earlier this year, most states learned that their average scores in grades 4 and 8 reading and mathematics remained relatively flat since 2015. More troubling though, students performing at the lowest 10th and 25th percentiles saw a decline in their scores. To confront this…

Executive leadership of the U.S. Department of Education (USDOE) initiated a flexibility offering from No Child Left Behind. Our work explores specific design decisions made in these state-specific accountability systems as associated with state political environments, resources, and demographic characteristics. Our analysis, focused on 42 states…

California's K-12 system relies on the Smarter Balanced Assessment Consortium (SBAC) English and mathematics tests to measure student academic progress and assess school and district performance. This report uses publicly available data to explore trends in student performance during the first three years this test has been in place. Key findings…

Through educational connoisseurship and criticism, this study explores how labels based on standardized student growth affect a rural school in Colorado. While the educators express intentions to help their students to demonstrate academic growth and achievement, they also have concerns that focusing on growth might compromise the well being of…

The No Child Left Behind Act (NCLB) was signed into law in 2001, fueled by bipartisan concern about the standardized test scores of U.S. students in comparison with their international cohort and dissatisfaction with gaps in achievement between certain student groups--low income, English-language learners, special education, and students of…

A companion piece to "High Stakes for High Achievers: State Accountability in the Age of ESSA," this report appraises states' current (or planned) accountability systems as they affect high-achieving students in high school. They were examined and rated based on whether they incorporate under the Every Student Succeeds Act (ESSA) the…

This memorandum presents results from the Center on Standards and Assessment Implementation's (CSAI) scan of growth models proposed in Elementary and Secondary Education Act (ESEA) waivers, with a focus on U.S. states' and territories' differentiation of students who participate in special education programs.

As States and districts implement educator evaluation systems that include measures of student growth, one of the challenges they face is identifying measures for non-tested grades and subjects. Using student learning objectives (SLOs) is one promising approach to addressing this challenge. This brief describes the key elements and challenges of…

In this report, student growth percentiles and percentile growth projections/trajectories are introduced as a means of understanding student growth in both normative and a criterion referenced ways. With these values calculated, the author shows how growth data can be utilized in both a norm- and in a criterion-referenced manner to inform…
