Younger students have regained academic ground lost during the pandemic, but older students' test scores remain stagnant. That's according to the latest testing data released Wednesday by the federal government. The report shows 9-year-olds have returned to pre-pandemic reading levels and improved in math. But scores for 13-year-olds in math and reading are still below pre-pandemic averages. Schools have focused on revamping elementary instruction, especially in reading, but experts say more attention is also needed for adolescents, especially middle schoolers. The national test has been given every four years since the 1970s. Students' scores peaked in 2012, then declined, corresponding with the rise of social media on cellphones.

The state of Florida has filed a lawsuit against OpenAI and CEO Sam Altman, claiming the company knowingly released and aggressively marketed ChatGPT to the public while concealing serious risks. Florida Attorney General James Uthmeier said Monday that the company suppressed internal safety warnings and deceived users about the true nature and dangers of the product. The lawsuit mentioned two recent criminal cases in which the suspects allegedly used OpenAI to plan the attacks. OpenAI says its models repeatedly encouraged the individuals to seek real-world support, including from mental health professionals. The company also says it has cooperated with law enforcement in both cases.
