[5] When the Second World War created a teacher shortage in Alberta, the Correspondence Branch turned to radio instruction.

In 1940, the first lessons were broadcast on the CKUA Radio Network — the University of Alberta's radio station[7] As the demand for high school services surpassed those for elementary and junior high programs, the Branch worked with the province-owned public educational television station, ACCESS TV (currently CTV Two Alberta), to begin televised instruction in the early 1970s.

[8] In preparation for the move, the province commissioned the construction of a new building, situated in the north industrial area of Barrhead.

[7] The name change was meant to reflect the shift from print-based correspondence education to distance learning using both print and non-print media.

[9] ADLC continued to share a building with Alberta Education, who retained control over the development and design components of the operation.

Teacher Support provides instructors with customizable resources, including sample lesson plans that can be used to deliver various courses to students.

[10] In August 2020, the Alberta Distance Learning Centre (ADLC) announced that its education programming would cease following the completion of the 2020–2021 school year.
