We present the first quantitative analysis of the impact of ending de jure segregation of Mexican-American school children in the United States by examining the effects of the 1947 Mendez v. Westminster court decision on long-run educational attainment for Hispanics and non-Hispanic whites in California. Our identification strategy relies on comparing individuals across California counties that vary in their likelihood of segregating and across birth cohorts that vary in their exposure to the Mendez court ruling based on school start age. Results point to a significant increase in educational attainment for Hispanics who were fully exposed to school desegregation.
High school exit exams are meant to standardize the quality of public high schools and to ensure that students graduate with a set of basic skills and knowledge. Evidence suggests that a common perverse effect of exit exams is an increase in dropout for students who have difficulty passing tests, with a larger effect on minority students. To mitigate this, some states offer alternative, non-tested pathways to graduation for students who have failed their exit exams. This study investigates the post-secondary effects of an alternative high school graduation program. Among students who initially fail an exit exam, those who eventually graduate through an alternative project-based pathway have lower college enrollment, but similar employment outcomes to students who graduate by retaking and passing their exit exams. Compared to similar students who fail to complete high school, those students who take the alternative pathway have better post-secondary outcomes in both education and employment.
The Top 10% Plan admissions policy has now been in place in Texas for over two decades. We analyze 18 years of post-Top 10% Plan data to look for evidence of increased access to the selective Texas flagship campuses among all Texas high schools. We provide a detailed description of changes in enrollment patterns at the flagship campuses from Texas high schools after the implementation of the Top 10% Plan, focusing on whether the policy resulted in new sending patterns from high schools that did not have a history of sending students to the flagship campuses. Our analysis reveals an increase in the likelihood that high schools in non-suburban areas sent students to the flagship campuses, but ultimately little to no equity-producing effects of the Top 10% Plan over this 18-year period. In fact, the representation of traditional, always-sending, feeder high schools on the flagship campuses continued to dwarf the population of students from other high schools. Thus, the purported high school representation benefits of the policy appear to be overstated and may not go as far as advocates might have hoped in terms of generating equity of access to the flagship campuses in the state.
The time children spend with their parents affects their development. Parenting programs can help parents use that time more effectively. Text-messaged-based parenting curricula have proven an effective means of supporting positive parenting practices by providing easy and fun activities that reduce informational and behavioral barriers. These programs may be more effective if delivered during times when parents are particularly in need of support, such as after work, or, alternatively when parents have more time to interact with their child, such as on a day off of work. This study compares the effects of an early childhood text-messaging program sent during the weekend to the same program sent on weekdays. We find that sending the text messages on the weekend is, on average, more beneficial to children’s literacy and math development. This effect is particularly strong for initially lower achieving children, while the weekday texts show some benefits for higher achieving children on higher order skills. These results are consistent with the hypothesis that the parents of lower achieving students, on average, face such high barriers during weekdays that supports are not enough to overcome these barriers, while for parents of higher achieving students, weekday texts are more effective because weekdays are more challenging, but not so difficult as to be untenable for positive parenting. In sum, the findings suggest that parenting support works best when parents have time, attention, and need.
Text-message based parenting programs have proven successful in improving parental engagement and preschoolers’ literacy development. The tested programs have provided a combination of (a) general information about important literacy skills, (b) actionable advice (i.e., specific examples of such activities), and (c) encouragement. The regularity of the texts – each week throughout the school year – also provided nudges to focus parents’ attention on their children. This study seeks to identify mechanisms of the overall effect of such programs. It investigates whether the actionable advice alone drives previous study’s results and whether additional texts of actionable advice improve program effectiveness. The findings provide evidence that text messaging programs can supply too little or too much information. A single text per week is not as effective at improving parenting practices as a set of three texts that also include information and encouragement, but a set of five texts with additional actionable advice is also not as effective as the three-text approach. The results on children’s literacy development depend strongly on the child’s pre-intervention literacy skills. For children in the lowest quarter of the pre-treatment literacy assessments, only providing one example of an activity decreases literacy scores by 0.15 standard deviations relative to the original intervention. Literacy scores of children in higher quarters are marginally higher with only one tip per week. We find no positive effects of increasing to five texts per week.
