Abstract
© 2020 Support for policies to improve early childhood educational development and reduce disparities grew rapidly this century but recently has wavered because of findings that program effects might fade out prematurely. Two programs implemented at scale in North Carolina (Smart Start and More at Four) have been associated with academic success early in elementary school, but it is not known whether these effects fade out or are sustained in middle school. Smart Start provides state funding to support high-quality early childcare in local communities, and More at Four provides state-funded slots for a year of credentialed pre-kindergarten. Funds were allocated for each program at varying rates across counties and years. We used this variation to estimate the long-term impact of each program through eighth grade, by measuring the association between state funding allocations to each program, in each of 100 counties over each of 13 consecutive years, and later student performance. Students were matched to funding levels provided to their home county in their early childhood years and then followed through eighth grade. Analyses using county- and year-fixed-effects regression models with individual- and school-level covariates conducted on nearly 900,000 middle school students indicate significant positive impacts of funding for each program on reading and math test scores and reductions in special education placement and grade retention. These impacts do not fade out and seem instead to grow (for More at Four) as students progress through middle school. Students from economically disadvantaged backgrounds experience particularly large benefits from the More at Four Program.

Helen F. Ladd
Helen F. Ladd is the Susan B. King Professor Emerita of Public Policy and Economics at Duke University’s Sanford School of Public Policy. Her education research focuses on school finance and accountability, teacher labor markets, school choice, and early childhood programs. With colleagues at Duke University and UNC, she has used rich longitudinal administrative data from North Caroline to study school segregation, teacher labor markets, teacher quality, charter schools, and early childhood programs. With her husband, Edward Fiske, she has written books and articles on education reform efforts in New Zealand, South Africa, the Netherlands, and England.
She is the co-author or co-editor of 12 books. These include Holding Schools Accountable: Performance-Based Reform in Education (Brookings Institution, 1996); The Handbook of Research in Education Finance and Policy (2008 and second edition 2015), books on school reform in New Zealand and South Africa, and Educational Goods: Values, Evidence and Decision Making (University of Chicago Press, 2018).
From 1996-99 she co-chaired a National Academy of Sciences Committee on Education Finance. In that capacity she is the co-editor of two books: a set of background papers, Equity and Adequacy in Education Finance and the final report, Making Money Matter: Financing America’s Schools.
In 2011, she was elected to membership in the National Academy of Education. During 2016 and 2017 she served as a member of a National Academy study of financing early care and education with a highly qualified workforce. She is currently a member of the N.C. Governor's Commission on Access to a Sound, Basic Education.
She was president of the Association for Public Policy and Management in 2011 and, from its founding in 2008 until 2017 was co-chair of the national campaign for a Broader, Bolder Approach to Education.
Prior to 1986, she taught at Dartmouth College, Wellesley College, and at Harvard University, first in the City and Regional Planning Program and then in the Kennedy School of Government. She graduated with a B.A. degree from Wellesley College in 1967, received a master's degree from the London School of Economics in 1968, and earned her Ph.D. in economics from Harvard University in 1974.
Early in her career, her research focused on state and local public finance, and she was active in the National Tax Association, which she served as president in 1993-94. She has also been a visiting scholar at the Federal Reserve Bank of Boston, a senior research fellow at the Lincoln Institute of Land Policy, and a visiting fellow at the Brookings Institution.
With the support of two Fulbright grants, she spent the spring term of 1998 in New Zealand studying that country’s education system and the spring term of 2002 doing similar research in South Africa. More recently, she spent a term as a visiting researcher at the University of Amsterdam examining the Netherlands’ long experience with parental choice and weighted student funding, and two months in London at the Institute for Fiscal Studies pursuing research on school improvement and English academies.

Clara G. Muschkin
Clara Muschkin is an associate research professor emerita of public policy at Duke University and an affiliate of the Center for Child and Family Policy. She directed the Child Policy Research Certificate Program and was the faculty director for the North Carolina Education Research Data Center (NCERDC).
Muschkin is a sociologist and demographer with an interdisciplinary research focus. In her research, she asks how education policies that influence the composition and organization of educational institutions can influence student behavior and academic performance. Her current research interests include: the impact of early childhood education policies on subsequent student outcomes; the impact of grade configuration on student behavior; the influence of grade retention and age on behavior and academic performance; impact of school composition by race and immigrant status on student behavior and achievement across grade levels; evaluation of high school reform policies; and successful outcomes for community college students.
