The school was accredited in 1932, and that same year the school had its first graduating class of 13 members. In 1935 the Alumnae Association was established with most of its efforts directed toward communication, reunions, special events for alumni and the annual alumni phonathon. By 1943, Holy Angels had discontinued its grade school but continued to offer Kindergarten until 1946, when St. Peter's Church next door opened its parish elementary school. The 1952–1953 school year was the last year for boarders to live at Holy Angels, and 1953 marked the beginning of Holy Angels solely as a day school.
