Students will now attend Mother Teresa Regional Catholic School in King of Prussia, Pennsylvania.

As the school population grew, this open section was divided into temporary classrooms by using portable blackboards.

The Sisters, Servants of the Immaculate Heart of Mary, staffed Saint Teresa of Avila School.

Most of the early classes were combined, with children from 2 grades being taught by a single teacher in one room.

In 1974, Father Walsh oversaw the establishment of a kindergarten and in 1980, the nursery school program for 3 and 4 year olds.

Father Francis Kelly became the new Pastor of Saint Teresa of Avila, and in September 1990, the school began its first year under an all lay faculty headed by Mrs. Maria Brown, Principal.
