The D.C. Public Schools have decided how students will make up the four-and-a-half days in the classroom they lost due to Snowpocalypse 2010.

As LL noted earlier this month, students will be expected on June 21 and 22—-the built-in make-up days scheduled for the Monday and Tuesday after school was originally slated to end. In addition: Students will attend on March 19, originally a “professional development” day for teachers, and May 17, originally slated for parent-teacher conferences. And June 18, originally a half-day, is now a full day.

What DCPS didn’t do: Add time to the school day, shorten spring break, or take away the Emancipation Day holiday. “[U]ltimately these scenarios were too costly,” says a DCPS release.
