By the early 1920’s the original curriculum was expanded. The original classes in mathematics, English, history, Latin, German, and French were augmented with sciences, Bible class, current events, physical education, and singing. These early years became the foundation of many traditions that have continued throughout the years including student government, the adoption of a uniform, Parent’s Day, and much more.
By 1928, The Miss Hockaday School for Girls had only been open 15 years, but it had acquired a national reputation as a leading preparatory school for girls. There were more girls passing college entrance examinations from Hockaday than any other school in the southwest or Philadelphia. Teachers were also appointed to serve as committee members for college entrance examinations.
