When Ja’Kobi Moore decided to apply this year to a private high school in her hometown of New Orleans, she learned that she needed at least one letter of recommendation from a teacher. She had never asked for one, so she sought help.

"Teacher letter of recommendation,” she typed into TikTok’s search bar.

Moore, 15, scrolled TikTok’s app until she found two videos: one explaining how to ask teachers for a recommendation letter and the other showing a template for one. Both had been made by teachers and were easier to understand than a Google search result or YouTube video, said Moore, who is planning to talk to her teachers this month.
