Holbein, John B.; Ladd, Helen F. – National Center for Analysis of Longitudinal Data in Education Research (CALDER), 2015
In this paper we examine how failing to make adequate yearly progress under No Child Left Behind (NCLB), and the accountability pressure that ensues, affects various non-achievement student behaviors. Using administrative data from North Carolina and leveraging a discontinuity in the determination of school failure, we examine the causal impact of…

Clotfelter, Charles T.; Ladd, Helen F.; Muschkin, Clara G.; Vigdor, Jacob L. – National Center for Analysis of Longitudinal Data in Education Research, 2012
Community colleges are complex organizations and assessing their performance, though important, is difficult. Compared to four-year colleges and universities, community colleges serve a more diverse population and provide a wider variety of educational programs that include continuing education and technical training for adults, and diplomas,…

Ladd, Helen F. – Journal of Policy Analysis and Management, 2012
Current U.S. policy initiatives to improve the U.S. education system, including No Child Left Behind, test-based evaluation of teachers, and the promotion of competition are misguided because they either deny or set to the side a basic body of evidence documenting that students from disadvantaged households on average perform less well in school…

Clotfelter, Charles T.; Ladd, Helen F.; Vigdor, Jacob L. – National Center for Analysis of Longitudinal Data in Education Research, 2012
In 2002/03, the Charlotte-Mecklenburg Schools initiated a broad program of accelerating entry into algebra coursework. The proportion of moderately-performing students taking 8th grade algebra increased from less than half to nearly 90%, then reverted to baseline levels, in the span of just six age cohorts. We use this policy-induced variation to…

Ladd, Helen F.; Lauen, Douglas L. – Journal of Policy Analysis and Management, 2010
Although the federal No Child Left Behind program judges the effectiveness of schools based on their students' achievement status, many policy analysts argue that schools should be measured, instead, by their students' achievement growth. Using a 10-year student-level panel data set from North Carolina, we examine how school-specific pressure…

Ladd, Helen F. – Sanford School of Public Policy, 2011
Current U.S. policy initiatives to improve the U.S. education system, including No Child Left Behind, test-based evaluation of teachers and the promotion of competition, are misguided because they either deny or set to the side a basic body of evidence documenting that students from disadvantaged households on average perform less well in school…

Bifulco, Robert; Ladd, Helen F.; Ross, Stephen L. – Peabody Journal of Education, 2009
Using student-level data from Durham, North Carolina, we examine the potential impact of school choice programs on the peer environments of students who remain in their geographically assigned schools. We examine whether the likelihood of opting out of one's geographically assigned school differs across groups and compare the actual peer…

Bifulco, Robert; Ladd, Helen F.; Ross, Stephen – National Center for Analysis of Longitudinal Data in Education Research, 2008
Using evidence from Durham, North Carolina, we examine the impact of school choice programs on racial and class-based segregation across schools. Theoretical considerations suggest that how choice programs affect segregation will depend not only on the family preferences emphasized in the sociology literature but also on the linkages between…

Clotfelter, Charles T.; Ladd, Helen F.; Vigdor, Jacob L. – National Center for Analysis of Longitudinal Data in Education Research, 2007
We use data on statewide end-of-course tests in North Carolina to examine the relationship between teacher credentials and student achievement at the high school level. The availability of test scores in multiple subjects for each student permits us to estimate a model with student fixed effects, which helps minimize any bias associated with the…

Clotfelter, Charles T.; Ladd, Helen F.; Vigdor, Jacob L. – Terry Sanford Institute of Public Policy, 2008
Using detailed administrative data for the public K-12 schools of North Carolina, we measure racial segregation in the public schools of North Carolina. With data for the 2005/06 school year, we update previously published calculations that measure segregation in terms of unevenness in racial enrollment patterns both between schools and within…

Bifulco, Robert; Ladd, Helen F. – Education Next, 2005
In this paper, the authors use an extensive student-level data set to evaluate the impact of charter schools in North Carolina on the math and reading performance of students in grades 4 through 8. They address three main questions: Do students attending charter schools in these grades make larger or smaller gains in achievement than they would…
