A North Penn School Board committee is looking at ways to save money on transportation costs. The options could include having public and parochial school students ride on the same buses.  For example, some Lansdale Catholic students could ride with North Penn High School students, while Saint Stanislaus students could ride with Knapp Elementary School students and Corpus Christi students could ride with Gwynedd Square students.  The committee is also considering requiring about 37 Saint Stan’s students who took the bus in the past to walk.
