• If the course your child needs to make up in summer school is offered at Muhlenberg High School this summer, your child must take that course in our district.  If the course is not offered at MHS, the student may take the course at another school district who may be offering that course.  Summer school information for Wilson School District is available in the high school guidance office.  Summer school questions can be directed to your child's school counselor at 610-921-8078, ext. 4107.
