The Association was established under the name of the Association of Engineering Technicians and Technologists of Newfoundland AETTN in 1968 with the sponsorship of the Association of Professional Engineers of Newfoundland. In 1993 AETTN was Incorporated. In recent years, AETTN has been accepting an increasing portion of the financial, staffing and certification load. With increasing membership, the Association has assumed full responsibility and maintained its own office under the directorship of Lynda Hayward as Office Manager.
At the 35th Annual General Meeting held at the Glynmill, Corner Brook, NL on October 4, 2003 the general membership voted in favour to change the name of the association from the Association of Engineering Technicians and Technologists of Newfoundland (AETTN) to the Association of Engineering Technicians and Technologists of Newfoundland and Labrador Inc. (AETTNL)
