[2] High school students may choose to attend Lehigh Career and Technical Institute for vocational training in the trades.

[9] The next year, in 1930, the Annex and Little Palestra were built to provide additional classroom space, an indoor gymnasium and swimming instruction.

[6] After World War II, additional expansion was made with the acquisition of the Mack and Farr buildings, which were located across Seventeenth Street on the South Side of Linden.

Cloud Street building, was opened, which provided room for masonry and auto body repair training.

Those classes were moved in 1957 to the new Brick and Auto Body building, which was opened at the unused Coffield site, and the seats were removed in 1955 to be the visitor's stand on the south side of the ASD stadium along Linden Street.

The students living west of Seventh Street remained assigned to Allentown High School.

Also that year, the Coffield athletic field was redeveloped, and the new William Allen High School gymnasium/natatorium was erected on the site.

In the other buildings, renovations include upgraded science lab equipment, new tables in the cafeterias, a multimedia center, upgrades in the black box theater, hundreds of new and refurbished classroom spaces, and elevators were installed in buildings that to provide accessible facilities for the disabled.

As part of the major renovation, $1 million was spent on the auditorium's upgrading, which includes new curtains, seating, an imported stretched oil on canvas portrait above the stage, restoration of historic plasterwork that adorns the walls and ceilings, and a 15 ft stage extension.

William Allen is one of 18 large high schools competing in the Eastern Pennsylvania Conference, one of the nation's premier athletic divisions.

William Allen High School's alma mater was written by Dorothy Newhard Knoff in 1912, and was set to music composed by Dr. Warren F. Acker in 1900.

[15] All hail our Alma Mater dear, Our voice of praise and glory hear To whom all reverence we bear, Of you forgetful we'll be ne'er.

We shall forever for you yearn And cherish all that we may learn Through future days of life, 'Mid joy and strife; True may we stand, both to you And Canary and Blue.

Throughout the land of you we'll sing, Loud will our praises ever ring, Of days that have passed by, Fond memories of dear old high.

Oh Alma Mater, hear our praise; To you all honor we do raise; Through future days of life, 'mid joy and strife; True may we stand, both to you And Canary and Blue.
