Transitional Kindergarten (TK) is a relatively recent entrant into the U.S. early education landscape, combining features of public pre-K and regular kindergarten. We provide the first estimates of the impact of Michigan's TK program on 3rd grade test scores. Using an augmented regression discontinuity design, we find that TK improves 3rd grade…

Grade-level retention is a common educational practice with the goal of improving academic performance, but the evidence of its influence is mixed. This study examines the academic effect of repeating kindergarten, first grade, second grade, or third grade on English Language Arts performance at the end of fourth grade. This study also examines…

In 2006-2007, California revised its English language proficiency (ELP) assessment, the California English Language Development Test (CELDT), which resulted in more stringent criteria and higher cut scores for meeting proficiency. Using regression discontinuity designs and a difference-in-differences approach, this study examines the effects of…

Many states and school districts in the United States use standardized test scores to compute annual measures of student achievement progress and then use school-level averages of these growth measures for various reporting and diagnostic purposes. These aggregate growth measures can vary consequentially from year to year for the same school,…

This article compares developmental kindergartens of the past to current academic kindergartens through the voices of kindergarten teachers who taught in both types. Data were obtained from interviews of ten public school kindergarten teachers from California with experience in kindergarten ranging 18-34 years (M = 24). Teachers indicated that…

New York State's system of public elementary and secondary schools is in steep decline, but it is salvageable. The roots of its problems pre-date the onset of the COVID-19 pandemic in early 2020, but the system's response to that challenge accelerated discontent with the schools and harmed students. The damage of those years will not be undone if…

We estimate relative achievement effects of the four most commonly adopted elementary mathematics textbooks in the fall of 2008 and fall of 2009 in California. Our findings indicate that one book, Houghton Mifflin's "California Math," is more effective than the other three, raising student achievement by 0.05 to 0.08 student-level…

As students return to full in-person learning in 2021-22, California public schools face considerable challenges brought on by the COVID-19 pandemic.
