An article in the Hechinger Report highlighted Assistant Professor of Public Policy R. Jisung Park’s research findings on the relationship between heat and student test performance. Air pollution and heat are becoming increasing concerns as a result of climate change, and research indicates that these factors may inhibit student performance in classrooms. In a study conducted in New York City, Park found that hot testing days reduced students’ performance on Regents exams, which are required for graduation in New York, thus decreasing the probability of a student graduating from high school. He found that students are 10% more likely to fail an exam when the temperature is 90 degrees than when it’s 72 degrees. Park also co-authored a study that examined PSAT scores across the country and found that students “had lower scores if they experienced hotter school days in the years preceding the test, with extreme heat being particularly damaging.”
About 30 undergraduate students from California and beyond convened at UCLA for a weekend of learning and public service, part of the not-for-profit Public Policy and International Affairs (PPIA) program. UCLA Luskin Public Policy hosted the program, “Advancing Social Justice Through Public Service: Lessons From California,” with senior lecturer Kenya Covington coordinating a full weekend of lectures, conversations and off-campus experiences. Students ventured out to MacArthur Park west of downtown Los Angeles, the Crenshaw District and the office of Los Angeles County Supervisor Sheila Kuehl to hear how policymakers are grappling with homelessness and gentrification. They heard from several MPP alumni from both the policy field and academia, and learned about public service career paths from Dean Gary Segura and other UCLA Luskin staff. Several members of the public policy and urban planning faculty shared research, insights and data-gathering techniques during the Oct. 4-6 event, including Amada Armenta, Kevin de León, Michael Lens, Michael Stoll and Chris Zepeda-Millán. Public Policy Chair JR DeShazo encouraged the students to engage intellectually, socially and emotionally as they explored policy challenges and prepared to make an impact in their own careers. The students formed working groups to synthesize what they had seen and heard, and presented their findings at the close of the program. Joining the large contingent of students from four-year and community colleges in California were participants from Arizona, Illinois, Michigan and Washington. The public service weekend was one of several outreaches around the country that are coordinated through PPIA to promote diversity in public service.

PBS NewsHour took an in-depth look at Assistant Professor of Public Policy R. Jisung Park’s research linking extreme heat and students’ ability to learn. Every 1-degree-Fahrenheit increase in average outdoor temperature over a school year reduces student learning by 1 percent, a team of researchers led by Park found. The team’s analysis of weather data, test scores for 10 million students, and access to air conditioning in classrooms across the country point to a “Dixie divide”: In hotter counties in Florida, Texas and other Southern states, test scores were lower than those in the North, even after controlling for factors such as family income, a county’s economic status or local pollution. “The causal effect of any given 90-degree day was much larger for lower-income students and racial minorities,” added Park, associate director of economic research for the Luskin Center for Innovation. The study puts a spotlight on the nuanced ways that developed nations will be influenced by global warming.
R. Jisung Park, assistant professor of public policy, spoke with KPCC’s “Take Two” about his research linking extreme heat with the racial education achievement gap. Students who experience more hot days during the school year perform worse on standardized exams, Park and his colleagues found. In addition, black and Hispanic students are 9 percent less likely than white students to attend schools with functioning air conditioning, they found. “We know that that can have effects on the economic opportunities that these students can have access to,” Park told “Take Two” in a segment beginning at minute 23:40. Park, associate director of economic research for the Luskin Center for Innovation, advocates for air conditioning powered by clean energy. “In the meantime,” he said, “we need to protect the most disadvantaged communities from the effects of climate change that are already coming down the pike.” Park’s research was also highlighted in USA Today and the Washington Post.
Jisung Park, assistant professor of public policy and environmental health sciences, was interviewed by the Dutch daily newspaper NRC Handelsblad about his research on the effects of heat on learning and test scores for students in the United States. Asked about the effect of climate change on productivity, Park said, “In a modern economy, schools are the places where the wealth of a nation is created. That is where the knowledge and the skill comes from.” Park suggested that countries with moderate climates, like the Netherlands, adopt heat policies as temperatures climb worldwide. “I think that is why we should be just as concerned about the environment in which a student learns as the environment in which a worker works.”
A study by R. Jisung Park, assistant professor of public policy, is cited in the online story that accompanies a recent NPR “Morning Edition” piece about the impact of hot weather on brain function. Compared with a 72-degree day, “taking an exam on a 90◦F day leads to a 10.9 percent lower likelihood of passing a particular subject (e.g. Algebra), which in turn affects probability of graduation,” according to Park. The same quote, plus additional information from the study, is included in a data-driven story by the Washington Post headlined, “Heat Makes You Dumb, in Four Charts.”
