While policymakers have demonstrated considerable enthusiasm for "science of reading" initiatives, the evidence on the impact of related reforms when implemented at scale is limited. In this pre-registered, quasi-experimental study, we examine California's recent initiative to improve early literacy across the state's lowest-performing…

Continuous improvement is a holistic and research-based approach to education grounded in the belief that every system is designed to achieve the results it gets; therefore, change must be systemwide, not piecemeal. California is a national leader in the continuous improvement movement that is spreading throughout local school districts as well as…

English as a Second Language (ESL) learners' access and achievement in Algebra I was examined to determine whether ESL students continue to be denied equal opportunity-to-learn (OTL) as a result of unnecessary tracking practices. In this quasi-experiment, a pre-post retrospective comparison group design was used to determine the effects of the…

The Mathematics Diagnostic Testing Project (MDTP) offers course-specific assessments that provide teachers with timely feedback on their students' strengths and weaknesses in mathematics, often returning feedback to teachers on individual students and the entire class within a week of testing. In this way, teachers can quickly act on what they…

This paper profiles California's test score trends through 2008-09. Between 2005 and 2009, the percentages of students reaching the proficient level on the state test and the basic level on NAEP (National Assessment of Educational Progress) increased in grades 4 and 8 in both reading and math. Average annual gains were larger on the state test…

This report contains the findings and recommendations of the California Legislative Analyst concerning the Native American Indian Early Childhood Education program. The program was established in 1972 to increase competence in reading and mathematics among American Indian students in California rural schools by intervening in prekindergarten…

Disputing the claim that improved student learning requires stronger academic standards and stiffer tests, the authors of this book contend that effective state reform depends on coherence in policy and practice, and opportunities for professional learning. It draws on a study of a program in California that worked to improve mathematics teaching…

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…

In 1990, the National Assessment of Educational Progress (NAEP) included a Trial State Assessment (TSA); for the first time in the NAEP's history, voluntary state-by-state assessments (37 states, the District of Columbia, Guam, and the Virgin Islands) were made. The sample was designed to represent the 8th grade public school population in a state…

At the heart of the No Child Left Behind Act (NCLB) is the call for all students to be "proficient" in reading and mathematics by 2014. Yet the law expects each state to define proficiency as it sees fit and design its own tests. This study investigated three research questions related to this policy: (1) How consistent are various…
