Pittsburgh Public Schools are planning a phased return of students to the classroom beginning April 6, with the first spots reserved for the youngest learners and those who are struggling with online learning. The district late Monday announced student-support categories ahead of in-person instruction. The categories are based on students’ needs as well as a survey to assess families’ comfort level and desire for in-person hybrid learning. There are about 4,800 students identified for the earliest return date, officials said. Surveys will start going out to families this week.
