LAUSD students set to return to classes Wednesday; commuters brace for increased trafficLOS ANGELES (KABC) -- Hundreds of thousands of students in the Los Angeles Unified School District will return to classrooms Wednesday for the start of the school year, as the LAUSD faces budget concerns and the district implements restrictions on the use of digital devicesduring the school day. The restrictions are part of a broader district policy aimed at reducing student screen time across all grade levels. The district will also block student access to YouTube, social media and streaming platforms unless access is approved by a teacher. According to the district, the nation's second-largest, the move makes it "a national leader in setting thoughtful, research-based limits on student screen use and classroom technology tools." The district said the policy was developed after research and outreach to parents, teachers and community members.
