The Brief

California’s mandate requiring later start times for middle and high schools is already yielding results, with students sleeping more, reporting better mental health and scoring higher math and English scores, according to a new study.

The new working paper from the National Bureau of Economic Research examines the effects of Senate Bill 328, California’s statewide mandate for later school start times. The law, which went into effect in 2022, requires most middle schools to start no earlier than 8 a.m. and high schools no earlier than 8:30 a.m.

The study found that the new law increased the share of students sleeping at least eight hours per night by 13%, meeting the minimum recommended for adolescents by health experts. The largest jump was among boys.

The study shows that “rest and sleep are incredibly important in the function of schools,” said Osea Giuntella, an author of the report. Although the short-term increase in sleep is moderate, it has led to significant improvements in mental health and academic outcomes, he said.

Giuntella, a University of Pittsburgh researcher who studies sleep and economics, said the study’s first-year results are consistent with previous research linking better sleep to improved student well-being and academic performance. The study used changes in teachers’ commute arrival times from the American Community Survey as a proxy for later school start times, comparing sleep and mental health data before and after SB 328 took effect in the 2022-2023 school year and tracking academic gains from 2022 through 2025.

Gains in sleep, mental health, English and math

Students reported experiencing better mental health since schools shifted to later start times, with boys reporting the largest reductions in sadness, hopelessness and suicidal ideation, and Hispanic students reporting the biggest drop in difficulties concentrating.

Terra Ziporyn, executive director at nonprofit Start Schools Later and longtime advocate of later school start times, said SB 328 was a key part of California’s response to what schools have described as a student mental health crisis.

“The first step in addressing student mental health problems is to not create them in the first place,” Ziporyn said. “You can get a lot of counselors, but systematically depriving an entire adolescent population of adequate sleep is a surefire way to hurt their mental health.”

The study also found significant improvements in academic achievement, with eighth grade students making measurable gains in math and English, particularly among Hispanic and economically disadvantaged students.

Giuntella, the study’s author, said the improvement in scores was likely “largely driven by the change in sleep” based on comparable studies where increased sleep led to higher GPAs. That’s also why Hispanic students, who are already less likely to get adequate sleep than white students due to lower family income and family and work responsibilities, improved their math and English scores the most, Giuntella said.

Parents struggle with new schedules

The state mandate is the only one in the nation.

“California set a huge precedent for the whole nation by saying, ‘We cannot leave what is essentially a public health decision in the hands of local districts,’ ” Ziproyn said. “It’s not just a negotiable school budget item that you trade off against anything else.”

But some parents have said later start times complicate work commutes, push back sports and extracurricular activities and lead to some students simply pushing back the time they go to bed.

The study found that sports and extracurricular activities did start later after the change to later start times, but the changes were “marginal and not statistically significant,” Giuntella said.

“And it’s true that, yes, students may even go to bed a little later than they were, but they are definitely sleeping in more in the morning,” she said.

Guintella described later start times as just “one institutional factor” that may help address a complex sleep-deprivation problem, pointing to issues like the rise in nighttime screen use.

‘Too hard and too expensive’ for some districts

Some school districts found the transition to later school start times “too hard and too expensive,” Ziporyn said. Ziporyn said district administrators could have received more guidance from the state Department of Education to explain the benefits of later start times, and involve families in finding solutions to logistical problems.

“(Schools) have to fully understand why this is being done and communicate it with confidence to the community that they’re doing the right thing for kids,” Ziporyn said.

San Francisco Unified, for example, worked with operations experts at the Yale School of Management, Georgia Tech University and Northwestern University to redesign their bus routes in response to the change. With more than 120 schools and 18 different start times, the district generated about 1,000 new feasible bus schedules, which ended up saving the district about $5 million and with a majority of families and staff members satisfied with the transition to later start times, according to a report by Yale Insights. 

But most schools in California did not have access to dedicated consultants to ease the transition, Ziporyn said.

“California could have improved making these resources more readily available to the districts,” Ziporyn said. “Built into the law was that there was supposed to be help from the state Department of Education about getting this done, and building that community buy-in is part of it.”

Giuntella said the state can improve its implementation of SB 328 by collecting statewide data on later school start times to “assess the impact of the reform.” In the meantime, schools can take from the study that later start times are “effective and powerful tools” for student outcomes.

“This happens often with some shock to individual and families’ habits, and so it also requires the ability to navigate this transition in a way that doesn’t backfire,” Giuntella said.

The Los Angeles Unified School District shortened the application window for specialized academic programs this year, and will no longer accept paper forms.

Applications for the district’s magnet, dual language and affiliated charter schools for the next academic year opened Oct. 1 and are due Nov. 6, 2026.

How does it work?

If you want your child to attend their neighborhood school, enrollment is fairly straightforward. There’s a separate process for the district’s specialized programs called Choices.

There are two windows to apply — on-time and late. The latter consists of all the spaces left after families who applied on time accept their offers.

Here’s the timeline for the 2027-28 school year:

• Sept. 2026: School fairs start.
• Oct. 1, 2026: Choices application opens.
• Nov. 6, 2026:  Deadline to apply online.
• Dec. 1, 2026:  Late applications begin. 
• February 2027: On-time applicant results sent. 
• March 5, 2027: Deadline to accept or decline school offers for on-time applicants. School assignments for late applications follow the processing of on-time applications. Students may be offered a spot through the start of the spring semester. 
• Aug. 12, 2027: The school year begins.

LAUSD will no longer accept paper Choices applications. If families do not have a computer, they can use a smartphone to complete an application. LAUSD will also allow families to use computers at school parent centers.

How to prepare

Every child within LAUSD boundaries is assigned a school — find yours through the district’s “resident school identifier.”

But there are also hundreds of other programs available through the Choices process.

Those include:

• Magnets: Programs on a specific theme, such as science, math, language, advanced studies or art. These programs were originally established to integrate segregated schools and have a unique “points” system to prioritize applications. 
• Dual language or immersion: Students learn in English and in a second language such as Spanish, Mandarin, Korean or Armenian. 
• Affiliated charter schools: District-run schools with more freedom to try different types of teaching or other programs. 

No one type of school is inherently better than another, and no one metric defines a great school — there are many factors beyond test scores to consider, and we go over some of those here.

By far the most frequent piece of advice we’ve heard is to go on an in-person school tour if possible.

“The very best thing that people can do is go to the school and try to watch the way that educators interact with students, the way that students interact with each other, and the way that families are included or not in the life of a school,” said Jack Schneider, a University of Massachusetts, Amherst, education researcher and parent. “Once you do that, you really get a sense of what kind of place kids are going to school.”

Some schools post tour information online, but you may need to call for details.

LAUSD also hosts fairs, organized by geographic region, where multiple schools table and share information about their programs, through mid-October.

The Justice Department found Thursday that the law school at the University of California, Los Angeles, illegally considered race in admissions.

The announcement follows a similar finding against the university’s medical school and comes as President Donald Trump’s administration ramps up scrutiny of colleges’ processes for selecting students. The administration also has accused the UC Berkeley Law School and the medical school at the University of California, San Diego, of illegally discriminating against white and Asian applicants.

The UCLA School of Law said in a statement that it was committed to making admissions decisions in compliance with all applicable laws.

“Students are admitted through a comprehensive, merit-based review process that considers each applicant’s achievements and experiences,” the statement said. “We are confident in our process.”

Affirmative action in college admissions has been illegal since a 2023 Supreme Court ruling forbade it. The same ruling said colleges could continue to assess how applicants’ backgrounds might speak to broader characteristics, but Trump has accused colleges of using applicants’ personal statements and other proxies to consider race in admissions — which conservatives view as illegal discrimination.

The Justice Department’s investigation found UCLA’s law school discriminated against white and Asian American students by favoring Black and Hispanic applicants in its 2023, 2024 and 2025 incoming classes. Its analysis found the mean LSAT score was lower for admitted Black applicants than for admitted white applicants.

The department also said admissions staff at the law school instructed applicants during recruitment efforts, including one called the “Diversity Admissions Open House,” how to reveal their race in essays.

“Like many of its peer institutions, UCLA Law School runs a two-tiered admissions system whose academic bar for acceptance shifts up or down depending on the color of your skin,” said Harmeet Dhillon, head of the department’s Civil Rights Division, in a news release.

California voters ended affirmative action in college admissions in a 1997 ballot measure. In a brief filed in the Supreme Court case, the UC system said the change led to a precipitous drop in underrepresented minorities, especially at the system’s most selective campuses. The brief said UC went on to implement a range of race-neutral measures to increase diversity.

The Trump administration also has sued over the main UCLA campus’s response to allegations of antisemitic harassment. The administration’s latest finding sets the stage for a voluntary resolution to bring UCLA into compliance with the Justice Department’s legal interpretation or, if none can be reached, potential legal action.

Artist Hedy Torres asked a 20-something student from Cal State Northridge to sit for a portrait nearly a decade ago. Using charcoal on paper, she drew the dark-haired young man in black and white — but she deliberately kept the portrait unfinished.

The idea was that she would complete the piece if her subject, a DACA recipient named Lino de Jesús Pérez Cuevas, ever attained lawful permanent residency.

And now he has.

DACA, which stands for Deferred Action for Childhood Arrivals, is a program that provides two-year work permits and deportation relief for people who were brought to the U.S. as children. The permits can be renewed, but the program does not grant a pathway to citizenship. 

In late September, Pérez Cuevas — who is now married, a father, a green card holder and an adjunct instructor at his alma mater — sat with Torres once again.

Torres’ project involves interviewing subjects as she sketches them. This year, she invited the public to watch her complete the portrait as she spoke to Pérez Cuevas about what it took for him to get a green card and what that means for his life.

About two dozen people gathered at a community center in West Hollywood’s Plummer Park to see her add details to the piece that speak to the passing of time.

“I just wanted to make people empathetic to what [immigrants] go through during this process,” she said. “You have to be very patient. There is a lot of uncertainty.”

Responding to the potential loss of relief

Pérez Cuevas, who was born in the Mexican state of Oaxaca, was brought to the U.S. by his parents when he was 2.

When Torres drew him in 2017, he was pursuing a master’s degree in kinesiology at Cal State Northridge. That year, then-Attorney General Jeff Sessions announced intentions to rescind DACA, which had enabled him to set goals without the fear of being deported. A 2020 Supreme Court decision allowed the program to continue.

Torres was once undocumented herself, so she understood the 2017 announcement was earth-shattering for the approximately 800,000 people who were then in the program, she said.

That year, Torres was also a student at CSUN, working toward a master’s in fine art.

She recalled recently that she wanted people to see DACA recipients as people, not numbers. And so, for her master's project, she proposed creating portraits of DACA beneficiaries.

The portraits would be rooted in interviews conducted as she drew her subjects. Leaving them unfinished, she said, would symbolize the precarity of the moment.

The pieces would have enough detail for viewers to see the subjects’ faces clearly, particularly their eyes and expressions. Other elements, including their bodies and clothing, would be more of an initial sketch.

The university greenlit her project and gave her a grant to pursue it. There was just one problem: Torres had to convince reticent DACA recipients to share their stories.

Building trust 

When Torres first messaged Pérez Cuevas about the project, he ignored her for two weeks, he said. But because they had a mutual friend, he eventually agreed to meet with her.

“I was trying to see whether this person was just an academic trying to complete a project for her own benefit, or whether she really cared about the community,” he told LAist.

They met at a coffee shop. Pérez Cuevas learned about the artist’s journey from the Mexican state of Colima and everything she’d lived through since.

Before 2015, for example, an undocumented person in California could not get a driver’s license. When she was undocumented, Torres was stopped by police and had her car impounded. She said she had to cobble together thousands of dollars to get her car back from a tow yard.

Pérez Cuevas could relate. He had experienced the same thing.

He decided to trust her.

After she drew him, Pérez Cuevas helped Torres connect with more DACA recipients at the university. She drew four other portraits, which were also left unfinished.

These works were acquired by the university, with the agreement that Torres would be able to borrow and complete them when — and if — her subjects attained lawful permanent residency.

‘A sense of freedom’  

As she worked on the portrait, Torres added soft lines rendered in charcoal to the image of Pérez Cuevas’ face, along with a robust mustache. And she continued the interview.

“What did you imagine your life would be like when you were young?” Torres asked.

Thinking back to high school, Pérez Cuevas said he realized then that not having a social security number barred him from decent-paying work.

“I didn't really understand what I was doing with my life,” he said, adding that he used to not think higher education was for him even while he was at CSUN. “My state of mind was really dark back then.”

He credited a college counselor with helping him navigate school. He earned his degree in 2017.

Pérez Cuevas said he has intimate knowledge of what it’s like to live with constant uncertainty: not knowing how he would pay for college because he did not qualify for federal financial aid; not being able to travel outside the country; and waiting anxiously for federal officials to make decisions on immigration laws that could transform his life.

“I can't stress enough how difficult it is psychologically to wait because it's something that can revolutionize your life,” he said. “You're betting your whole life on this approval and just that suspense of waiting, waiting, waiting, living with that anxiety.”

Torres completed her portrait of Pérez Cuevas in September 2026. Four other portraits remain unfinished.

U.S. Citizenship and Immigration Services continues to process renewal requests for existing DACA recipients, but the agency is no longer approving first-time applications.

Under the second Trump administration, DACA recipients are also experiencing significant delays with renewals. Some have lost their jobs. Recipients have been deported. According to the agency, the median processing time for DACA renewals was one month in 2023. Currently, it’s taking seven months to process most cases.

Pérez Cuevas said he was able to adjust his immigration status after marrying a U.S. citizen and consulting with an attorney. His lawyer helped him secure a document that allowed noncitizens to travel abroad and seek legal re-entry.

“Did getting permanent residency give you a sense of freedom, a freedom you probably didn't have when you were under DACA?” Torres asked him.

“Absolutely,” Pérez Cuevas said. “The biggest freedom was psychological freedom. You have this weight that you've been carrying all these years that finally just gets thrown off your shoulders.”

One of the things he feared most was long-term separation from his parents, he said.

When his mother and father migrated to the U.S., they did not see their own parents — his grandparents — for 40 years, Pérez Cuevas added. After his parents moved back to Mexico during the pandemic, he feared they would also go decades without seeing each other.

But having a green card enables him to travel and see his family.

Pérez Cuevas told Torres that, paradoxically, the threat of losing DACA made him “weirdly ambitious."

He said he doubled down on his studies and took on every internship he could. He figured that if the U.S. decided to deport him, he’d still have his education and work experience.

“Even on the days where I didn't necessarily have the greatest energy or the greatest state of mind, I showed up for myself,” Pérez Cuevas said.

Southern California is expected to see the longest heat wave of the season.

The National Weather Service has issued an extreme heat warning for the greater Los Angeles area from Friday through at least next Thursday, and forecasters say it’ll likely extend beyond that.

Temperatures are expected to be in the mid-90s to mid-100s, even in coastal areas.

“Unfortunately, we don't really see an end to it as far as we can tell, and that's probably the biggest thing we wanna highlight, is that while we have had hotter events this season already, this one might be the longest-lasting,” said Ryan Kittell, a meteorologist with the National Weather Service.

Kittell said they expect to see a few daily records to be broken.

Southern California saw a record-breaking 10-day heat wave in the summer of 2022.

What does the hot weather mean for fire risk? 

Forecasters say conditions likely won’t meet the threshold for issuing red flag warnings (extremely dry air and windy conditions), but the risk of fire is still going to be high during the heat wave.

“It’s still concerning, and if a fire were to get started in the wrong area, it could grow pretty fast,” Kittell said. “ We do have a history of large fires in similar environments with similar heat, similar time of the year.”

As of Thursday afternoon, Southern California Edison said nearly 10,000 customers in parts of Riverside County were under consideration for power shutoffs, which are used to reduce the risk of electrical equipment starting a fire.

How do we manage through the heat? 

Kittell said people should make plans to stay cool during the long heat wave, and check in on neighbors who are elderly, or on families with young children.

Officials say residents should limit outdoor activities to the early morning hours, stay in air-conditioned places in the afternoon and evening hours, and stay hydrated.
