As 250 middle and high school students return to Guam school buildings on Tuesday for the first time since March, a question looms: How will the schools enforce safety and balance instruction? The Guam Education Board, in weekly meetings, has argued that giving schools the option of hosting classes in person supports schoolchildren from poorer backgrounds. But parents have resisted, reasoning that schools are not safe while coronavirus circulates on Guam. Since the last month, numbers for middle and high school students who signed up for in-person classes wavered in the single digits, while elementary school students improved to the mid-20's range, with a few schools approaching 50% or higher.
