Answer:
The “academic freeze”
It may not be the best solution, but an “academic freeze” can be adopted until the digital divide is fully resolved or results of mass testing and curve-flattening are already evaluated empirically. This will require a flexible academic term, calendar, and curricula to lessen the school days required, lower the number of course requirements, and reduce tuition and other fees usually projected for the use of school facilities.
An “academic freeze” can also be adopted through a “no vaccine, no classes” policy wherein all academic calendars and curricula need not to be adjusted, but will just have to suspend classes per academic year. If there is no vaccine yet as of 2020, it may be possible to suspend the Academic Year 2020 to 2021 and resume classes on the Academic Year 2021 to 2022 without adjusting the June to March and August to May academic calendars.
