The period 1920-25 saw the establishment of a number of academic units and changes to the curriculum. The School of Education was established by the Board of Regents in May 1921 and a university high school and an elementary school were established in 1922 and 1927 respectively. A growing public awareness of the desirability of teaching health and hygiene in the public schools led to the development of the Department of Physical Education in the School of Education. In 1923-24, Dr. Margaret Bell became Associate Professor of Women's Physical Education. The university organized a Division of Hygiene and Public Health in 1921. In the beginning this encompassed work in public health, physical education, intramural sports, and was closely related to the University Health Service. Eventually, these areas were divided into separate units.
