This annual event was originally organized in 1952 as "National Secretaries Week" by the National Secretaries Association (now known as the International Association of Administrative Professionals) in conjunction with public relations executive Harry Klemfuss and a consortium of office product manufacturers. It was established as an effort to recognize secretaries for their contributions in the workplace, and to attract people to secretarial/administrative careers.

In the year 2000, IAAP announced a name change for Professional Secretaries Week and Professional Secretaries Day. The names were changed to Administrative Professionals Week and Administrative Professionals Day to keep pace with changing job titles and expanding responsibilities of today’s administrative workforce.
