To date, small sample problems with latent growth models (LGMs) have not received the amount of attention in the literature as related mixed-effect models (MEMs). Although many models can be interchangeably framed as a LGM or a MEM, LGMs uniquely provide criteria to assess global data-model fit. However, previous studies have demonstrated poor…

The core work of the National Center on Scaling Up Effective Schools consists of four stages: identifying practices of highly effective high schools, designing interventions and transfer of practices, evaluating the intervention's implementation and effects, and evaluating implementation at scale. The purpose of this report is to describe the…

How many students repeat a grade each year? How do retention rates vary across states and over time? Despite extensive research on the predictors and consequences of grade retention, there is no systematic way to quantify state-level retention rates; even national estimates rely on imperfect proxy measures.

Describes a new analytical tool, data envelope analysis (DEA) model, which can provide better understanding of the efficiency of academic research libraries. Reports the results of a study using 1994-1995 Association of Research Libraries statistics together with expert judgments, in terms of constraints, to make the model more applicable to the…

This is a report which describes and evaluates a Summer Day Elementary School (SDES) program conducted in 1969 and involving 153 elementary schools in New York City.

Conventional accounting systems provide no indication as to what conditions and events lead to reported outcomes, since they traditionally do not include measurements of the human organization and its relationship to events at the outcome stage. Human resources accounting is used to measure these additional types of data. This research is…
