School districts have adopted the four-day school week to curb budget deficits, particularly in rural regions like Colorado and Wyoming, with around 10 districts in California following suit by 2011. This schedule change raises questions about its impact on academic performance. Longer class periods allow varied teaching methods and teacher planning, possibly improving student morale and behavior. Yet, concerns arise about teacher stress, student retention, and increased fatigue, especially for younger students. Evaluating this shift rigorously is vital, but few studies exist. Using a difference-in-differences regression and data from Colorado’s CSAP, researchers analyzed 4th-grade reading and 5th-grade math scores in districts that switched to a four-day week against those on standard schedules. Over a third of Colorado districts adopted this schedule. The results showed a significant increase in math scores post-switch, and while reading scores also rose, the change wasn’t statistically significant. The findings suggest no harm to student performance and even hint at improved attendance rates, though they apply primarily to smaller, rural districts, warranting caution in applying these findings more broadly.

A current study is exploring the impact of additional literacy classes on average-performing middle school students, aiming to enhance their high school performance and college readiness. In a suburban district with diverse demographics, students were offered extra literacy courses if they scored below the 60th percentile in 5th-grade literacy. While the initial analysis suggested no significant impact, further investigation revealed contrasting effects based on race. Black students experienced notably negative effects, especially in predominantly white schools, seen across both state tests and national measures. Conversely, white, Latino, and Asian students showed uncertain but potentially positive impacts. These findings stress the need for tailored approaches in educational programs, indicating potential harm for initially average-literacy students. The study highlights the complexity of policy outcomes when implemented at school levels, urging policymakers to consider diverse student populations in policy design and implementation. It also underscores the importance of clear communication about policy intent and the unintended consequences of categorizing students based on criteria like cutoff scores.

Educational institutions are increasingly revamping teacher evaluations, integrating student performance measures and classroom observations. LAUSD’s shift in evaluation systems and Vergara v. California’s ruling against certain teacher employment statutes spotlight this transformation. However, research across six urban districts reveals shifts in the role of value-added measures in decision making. Principals find value-added data problematic due to its infrequency, complexity, and limited applicability to teachers in untested subjects. Instead, they value the transparency, timeliness, and specificity of teacher observation systems, which provide comprehensive insights into teaching practices for all educators. While acknowledging differences between value-added and observation systems, research also emphasizes the advantages of teacher observation systems in informing timely and specific decisions. Despite concerns about observation systems’ time-intensive nature and the recent legal implications, these frameworks offer enhanced transparency and actionable feedback, potentially compensating for the limitations of value-added measures. Overall, the rise of observation systems signifies a positive step in leveraging data for informed human capital decisions in education.

The change in California's kindergarten entry age, moving the cutoff date from December 2 to September 1, brought about transitional kindergarten for affected children born in the transitional period. This impacted both those who delayed entry and those who didn't. Older entrants might show better readiness and learning skills compared to younger peers, a reason why parents often choose to delay their child's entry ("redshirting"). However, the benefits of this additional year might vary based on available activities. The shift also influences non-delayed children due to grade age averages affecting peer dynamics and learning. In a study assessing this change's impact on crime, incarceration rates dropped by 10-13% among those directly and indirectly affected by the entry age policy. While both groups benefitted, the reduction in crime was smaller for those delaying entry, hinting at potential harms from late entry, perhaps due to less learning during the "redshirt" year or lower educational attainment. This emphasizes early education's long-term benefits, supporting transitional kindergarten's role. Yet, caution is needed in generalizing these findings, considering the availability of alternative pre-kindergarten programs today, absent in earlier decades, possibly lessening the negative impacts of delayed entry.

Enrichment programs, such as arts education, often face cuts in K–12 schools where language arts and math take precedence due to standardized testing. Despite this, evidence supports the long-term benefits of the arts on college access, academics, and civic engagement. Integrating arts into school curricula is seen as a solution, yet there is limited research on its widespread implementation. Inner-City Arts collaborates with LAUSD through Learning and Achieving Through the Arts (LATA), where teachers learn various art forms alongside students, supported by professional development linking arts experiences with literacy. LATA aims to enhance English language skills, especially for marginalized groups like English Language Learners (ELLs), by promoting arts-based learning, teacher training, and teacher-artist collaborations for innovative lesson plans. A study comparing LATA-integrated schools with standalone arts instruction revealed significant gains in standardized English Language Arts (ELA) proficiency, particularly among ELL students, emphasizing the vital role of arts integration in academic achievement. Policymakers and investors interested in educational reform should prioritize integrated arts models and teacher development, as demonstrated by the LATA approach, which offers a holistic pathway to improve academics applicable in diverse urban districts.

The process of applying and enrolling in college is increasingly expensive and time-consuming, yet students often make less-than-ideal decisions during this crucial phase. Recent studies have shown that students tend to apply to too few colleges, and high-achieving, low-income students often miss out on better-suited options. A new research paper, "Screening Mechanisms and Student Responses in the College Market," explores how seemingly minor factors—such as college application essays and fees—impact student behavior. Analyzing data from 885 four-year colleges between 2003 and 2011, a new study reveals that the requirement of application essays increased to around 57%, while approximately half of colleges raised their application fees by an average of 30% (around $10). The research shows that colleges introducing essays experienced a 6.5% decrease in applications, while a 10% fee increase correlated with a 1% reduction in applications. This highlights that even small changes significantly influence student decisions in the college application process, emphasizing the importance of these procedures for students, colleges, and policymakers.

Education policies often focus on evaluating the effectiveness of interventions without considering their costs. This oversight limits policymakers’ ability to make informed decisions about resource allocation. Understanding intervention costs in relation to their effectiveness is crucial for efficient policymaking. For instance, reducing high school dropout rates, a national priority, could alleviate substantial economic burdens, yet education budgets are limited. Researchers conducted cost-effectiveness analyses on five dropout prevention programs, finding considerable variations in costs and effectiveness. Remedial programs aimed at dropouts were notably more expensive per additional graduate compared to preventative programs, which targeted at-risk students still in school. These findings emphasize the need for cost-effectiveness assessments in educational program evaluations to guide policymaking effectively. Without such analyses, research evidence alone may not provide policymakers with a comprehensive view for decision-making, potentially leading to inefficient resource allocation.
