Ackerman, D. & Coley, R. (2012). State pre-K assessment policies: Issues and status. Policy information report. Princeton, NJ: Educational Testing Service.
Preschool education is increasingly being recognized as an integral part of efforts to ensure that all children enter school ready to learn and as a way to help close the achievement gaps that exist at the time children enter kindergarten. Such efforts are growing across the country. According to the most recent data, 54 different preschool initiatives in 40 states serve over one million children, almost double the number served eight years earlier. As these programs and efforts to monitor them have grown, a common focus is on documenting children's learning outcomes. Assessing young children, however, presents particular challenges. This report identifies and describes state-funded Pre-K assessment policies and programs operating in 2012 and discusses the special challenges related to assessing young children. A table for specific child outcome measures that must or may be used as per Pre-K Policy is appended.

Blazer, C. (2012). Pre-kindergarten: Research-based recommendations for developing standards and factors contributing to school readiness gaps. Miami, FL: Miami-Dade County Public Schools, Research Services.
States across the country are developing pre-kindergarten standards that articulate expectations for preschooler's learning and development and define the manner in which services will be provided. There are two different types of standards: student outcome standards and program standards. Student outcome standards define the knowledge and skills children are expected to demonstrate by the end of their preschool year. Program standards describe characteristics of the preschool program, such as required teacher qualifications and student-teacher ratio. This Information Capsule provides a summary of research-based recommendations for policymakers and educators who are developing each type of standard. This paper also reviews factors that contribute to gaps in children's preschool readiness. The factor that has been found to correlate most highly with preschool learning disparities is family income level. Children's home learning environment, parents' level of educational attainment, ethnic and cultural influences, as well as parental beliefs and behaviors are also related to school readiness and school performance outcomes. However, since most of these factors are strongly tied to socioeconomic status, researchers have concluded that income level is the most powerful predictor of children's educational success. A brief discussion of the research, indicating that participation in high-quality preschool programs can significantly reduce early learning disparities by diminishing the negative effects of family and environmental risk factors, is included. Finally, a description of Miami-Dade County Public Schools' Pre-K programs is provided

Buenafe, A. (2011). Pre-K as a school turnaround strategy. Washington, DC: Pew Center on the States.
Across the nation, state and local school systems, recognizing the strong and growing evidence of pre-kindergarten's effectiveness in closing achievement gaps and improving school performance, are implementing early learning programs as part of their education reform efforts. In low-performing districts, pre-K has emerged as a promising turnaround strategy. As members of Congress discuss re-authorization of the Elementary and Secondary Education Act (ESEA) they can look at these initiatives to see how strategic use of limited funds for proven early education programs can raise student achievment, and to identify opportunities for smart federal investment.

Buysse, V., Peisner-Feinberg, E., & Burchinal, M. (2012). Recognition & response: Developing and evaluating a model of RTI for pre-k. Evanston. IL: Society for Research in Educational Effectiveness.
The Recognition & Response (R&R) model was developed and is being validated by a research team at the FPG Child Development Institute at the University of North Carolina at Chapel Hill. The Development and Innovation (IES Goal 2) study reported in this paper builds on an existing line of research that is focused on further development and evaluation of the R&R model, including adaptations for mathematics instruction, the integration of learning and behavioral interventions/supports, and instructional practices to support dual language learners, in addition to the current emphasis on language and literacy instruction. The study reported in this document is the second of two related studies. The purpose of this study was to design and evaluate the R&R model for use by pre-k teachers to address children's language/literacy skills. The study evaluated the feasibility, acceptability, implementation fidelity, and potential for improved classroom and child outcomes of this approach. Results suggest that the R&R system offers evidence of promise for improving language and literacy outcomes for young children. Positive effects were found in the growth rates for target children compared to their peers on formative assessment and standardized measures. Moreover, positive effects were found across different populations of children. Although these studies did not provide the opportunity for a true control group (given the requirements for Goal 2 Development and Innovation studies), the results clearly provide empirical evidence of the promise of R&R as an educational intervention for pre-k, and suggest that further research of the efficacy of this model is warranted.

Christina, R., & Goodman, J. (2005). Going to scale with high-quality early education. Pittsburg, PA: RAND.
This report is an initial effort to describe efforts of a number of states that are seeking to create statewide systems of high-quality pre-kindergarten services, as well as some of the progress they have made in doing so. Focusing on the efforts of a sample of eight U.S. states, it examines the policy choices that states have made when implementing pre-K in an environment of fiscal uncertainty and discusses policy and practice issues identified by respondents in the sector. The report should be of interest to policymakers and other stakeholders who are seeking to ensure that scaled-up pre-K is of high quality.

Educational equity is often discussed as a moral issue. Another way to think about equity is as a way to promote productivity and economic efficiency. The evidence is quite clear that inequality in the development of human capabilities produces negative social and economic outcomes that can and should be prevented with investments in early childhood education, particularly targeted toward disadvantaged children and their families.

This document synthesizes the results of a number of evaluation studies in an effort to determine whether early childhood interventions result in substantial benefits to participating children as they become adults, and whether they pay for themselves. Conclusions are that under carefully controlled conditions, early childhood interventions can yield substantial advantages to recipients. If these interventions can be sufficiently scaled up, the costs of the programs could be exceeded by subsequent savings to the government. Unfortunately, these conclusions rest on only a few methodologically sound studies. The authors argue for broader demonstrations accompanied by rigorous evaluations to resolve several important unknowns.

The authors consider the potential consequences of not investing additional resources in the lives of children, the range of early intervention programs, the demonstrated benefits of interventions with high-quality evaluations, the features associated with successful programs, and the returns to society associated with investing early in the lives of disadvantaged children. [Their] findings indicate that a body of sound research exists that can guide resource allocation decisions. This evidence base sheds light on the types of programs that have been demonstrated to be effective, the features associated with effective programs, and the potential for returns to society that exceed the resources invested in program delivery.

This is one in a series of policy briefs on key education issues prepared by the RAND Corporation for the Obama administration. Preschool education plays an important role in increasing school readiness and closing achievement gaps for children at risk. However, access to high-quality preschool programs varies greatly. Therefore, policymakers could use federal funds to support state efforts to improve preschool quality and access for the most disadvantaged children.

LaParo, K., Thomason, A., Lower, J., Kintner-Duffy, V., &Cassidy, D. (2012). Examining the definition and measurement of quality in early childhood education: A review of studies using the ECERS-R from 2003 to 2010. Early Childhood Research and Practice, 14(1), 13 pages.
The field of early childhood education continues to grapple with the issue of understanding quality in classrooms. The lack of clarity in definition (or conceptualization) and related ability to assess (or operationalize) quality has contributed to a reliance on the Early Childhood Environment Rating Scale (ECERS-R), which is often interpreted to be synonymous with the quality of a classroom. Likewise, the ECERS-R (although a measurement tool) is often used to define quality. Because of the widespread use of this measure as an evaluation tool, early childhood programs have strived to achieve high ratings on this measure, and subsequently the item content of the ECERS-R has often become a focus for quality enhancement initiatives. The present study examines the definitions of quality (i.e., how quality is operationalized) in research studies using the ECERS-R over the past 8 years (2003-2010). A content analysis of 76 studies conducted in the United States indicates that studies using the ECERS-R to operationalize quality do not use a consistent definition; instead they conceptualize quality in a variety of ways ranging from quality is ECERs or classroom quality to environmental quality. In light of these varying definitions, implications for research and policy in early childhood education are discussed.

Peisner-Feinberg, E., Schaaf, J., Hildebrandt, L., & La Forrett, D. (2013). Quality and characteristics of the North Carolina pre-kindergarten program. Chapel Hill, NC: University of North Carolina, Frank Porter Graham Child Development Institute.
The 2011-2012 evaluation study [of the North Carolina state Pre-K program] included information about characteristics of the NC Pre-K Program statewide and observations of classroom quality and teacher surveys in a random sample of 100 classrooms. The primary research questions addressed by this evaluation included: (1) What were the key characteristics of the local NC Pre-K programs?; (2) What was the quality of the NC Pre-K classrooms attended by children?; (3) What factors were associated with better quality?; and (4) To what extent were these results similar to past years under the More at Four Program? Key findings of this study include: (1) The NC Pre-K Program has not changed substantially in comparison to prior years of its predecessor program More at Four; (2) There were a few aspects in which the NC Pre-K Program differed in comparison to prior years of the More at Four Program; (3) NC Pre-K teachers generally reported being satisfied with their work environment; (4) NC Pre-K teachers reported that they planned to remain in the early childhood field; (5) The quality of classroom practices in NC Pre-K was in the medium to high range overall; and (6) The quality of the NC Pre-K classrooms was similar in almost all areas when compared to recent years of More at Four.

Tyler, K. (2012). The impact of the shifting knowledge base, from development to achievement, on early childhood education programs. Forum on Public Policy Online, 2012(1), 1-15.
Interest in child development as a knowledge base for early childhood education programs flourished in the 1970s as a result of the theories and philosophies of Jean Piaget and other cognitive developmentalists. During subsequent decades in America, reform movements emphasizing accountability and achievement became a political and social imperative, resulting in the 2002 U.S. Law No Child Left Behind (NCLB). The mandate of the NCLB emphasized consequential accountability, now permeating American schooling and curriculum development. The law's impact on early childhood education is discussed with selected professional judgments and data outlined particularly in federally designated Poor Black Belt Alabama counties. Finally, suggestions are offered regarding clarification of cognitive developmental theory with evidence of misunderstanding of Piaget's theory that may have weakened applicability to early childhood programs and curriculum. Political and professional discussions are included regarding modifications of the NCLB law allowing for regeneration of emphasis on child growth and development as a knowledge base for early childhood education.
