The authors evaluate the success of Arizona's program for English Learners (ELs) twelve years after the implementation of Proposition 203 to determine whether it meets the "third prong" test of Castañeda v. Pickard (1981), which requires a demonstration of the effectiveness of a program after its implementation. This study is a follow-up…

While the link between childhood abuse and future victimization has been developed, the effects of other negative events in childhood on future victimization, and whether protective factors may guard against it, remains unclear. To address this topic, the relationships between Adverse Childhood Experiences (ACES), protective factors, and violent…

We examined how the development of familism values from 5th to 10th grade relates to 12th-grade prosocial tendencies (after controlling for 10th-grade prosocial tendencies) using a stratified random sample of 749 Mexican American adolescents (M = 10.42 years of age at 5th grade; 48.9% girls) from 35 culturally and economically diverse…

Although studies have identified risk factors for adolescent handgun carrying, previous research on risk factors for carrying a handgun to school specifically is sparse. This study examines self-report data from 122,840 8th, 10th, and 12th grade students from 426 schools across Arizona, from three survey administrations (2014, 2016, and 2018). In…

We evaluated maternal gatekeeping attitudes as a mediator of the relation between marital problems and father-child relationships in 3 waves when children were in Grades 7-10. We assessed each parent's contribution to the marital problems experienced by the couple. Findings from mediational and cross-lagged structural equation models revealed that…

Background: Cluster-randomized experiments that assign intact groups such as schools or school districts to treatment conditions are increasingly common in educational research. Such experiments are inherently multilevel designs whose sensitivity (statistical power and precision of estimates) depends on the variance decomposition across levels.…

This study explored the relationships among the components of the Arizona Department of Education's new teacher evaluation model, with a particular focus on the extent to which ratings from the state model's teacher observation instrument differentiated higher and lower performance. The study used teacher-level evaluation data collected by the…

This year the Center on Education Policy (CEP) analyzed data on the achievement of different groups of students in two distinct ways. First, it looked at grade 4 test results to determine whether the performance of various groups improved at three achievement levels--basic and above, proficient and above, and advanced. Second, it looked at gaps…

Under the federal No Child Left Behind Act of 2001 (NCLB), standardized test scores are the indicator used to hold schools and school districts accountable for student achievement. Each state is responsible for constructing an accountability system, attaching consequences--or stakes--for student performance. The theory of action implied by this…
