Virtual learning days
Allentown has virtual learning days in its winter plan.
“Districts may choose to transition from in-person to remote instruction at any time, when appropriate, such as during inclement weather or emergencies. These days can be referred to as Virtual Learning Days.”Source
Making up a lost day
If necessary, student make-up days are February 12, March 25 and March 30, 2027; June 14 to 16 are make-up days for professionals.
“If necessary, make-up days for students due to emergency school closings will occur on February 12, March 30 & March 25”Source

How Pennsylvania counts a lost day
Pennsylvania requires either 180 days, or hours: 900 for kindergarten through grade 6 and 990 for grades 7 to 12, as the district chooses. The state forgives no days; districts are expected to build make-up days into the calendar for closures beyond any Flexible Instructional Days.
