Mechanicsburg Area Senior High School

MAY 2026

_{Spring Exams & Modified Schedules}

April 15, 2026

Dear Families,

As we approach the month of May, we would like to share an overview of our upcoming modified schedule. This includes adjustments to accommodate College Board AP Testing and Keystone State Testing, both of which are important components of our academic program.

Please also note that on May 28 and May 29, MASH students will follow a modified schedule with dismissal at 11:30 AM on both days.

In addition, this newsletter includes a link to our Senior Family Information, which outlines end-of-year expectations and important details for the Class of 2026. This resource includes information about required senior meetings leading up to commencement on May 29. While this senior information may not be relevant to current underclassmen, it may be helpful to preview general expectations of seniors during the latter part of their school year.

Thank you for your continued partnership and support.

Sincerely,

Joseph P. Reidy

Principal, MASH
