On October 15, Cardinal Dougherty of the Roman Catholic Archdiocese of Philadelphia dedicated the new building at 112 S. 7th Street, now Assumption BVM School, which still bears the engraving "P.C.H.

The constantly increasing enrollment made a new building imperative, and Monsignor John Boyle, then pastor of St. Patrick's, Pottsville, was commissioned by Archbishop John Joseph O'Hara of Philadelphia to purchase ground for the new diocesan high school.

Before Nativity BVM High School was built, burning crosses could be seen on top of Lawtons Hill from the area in and around Pottsville.

When Lawton's Hill was selected as the site for the new Catholic high school, the cross was a prominent theme in the building's design.

Windows of amber glass, facing westward, form one large cross that looks out from all three floors of the building.

Catholic high school students beginning their freshman, sophomore, junior, and senior years attended Nativity starting in September 1955.

The school was dedicated to the Blessed Virgin Mary on April 14, 1956, with Reverend John J. Nugent serving as the founding principal.

The first yearbook of Nativity BVM High School was called Ave Maria (Hail Mary) and was published in 1956.

During his tenure, the Allentown Diocese was formed from an area that had formerly been part of the Philadelphia Archdiocese.

In 1960, Catholic schools in Schuylkill, Berks, Carbon, Lehigh, and Northampton Counties became part of the new Allentown Diocese.

In 1961, a senior named John Vincent Egan graduated and enrolled at Saint Charles Seminary.

Soon the Holy Family Sisters joined other religious communities on the school faculty.

The school did not charge tuition at that time, although students had to buy their own books and pay an activities fee.

Seeing the need for an ongoing fundraiser, Father Nugent sought the help of local businessmen, who began plans for an annual dinner which they named the "Century Club" (after the nickname for a $100 bill) because the admission fee was $100.

By the early 1970s, Catholic schools had begun to charge tuition, and decreasing enrollment was a trend in most areas.

In 1978, the team finished its 34-1 season with a 46-41 victory over the Johnsonburg Area High School Rams on March 18 at the Hershey Park Arena to win the PIAA Class A girls' state basketball championship.
