St Patrick’s Technical College commenced operations as the Australian Technical College - Northern Adelaide in January 2007. In partnership with the Catholic Archdiocese of Adelaide and the Northern Adelaide Industry Consortium, the College was established by the Australian Government as part of an initiative to improve technical education facilities in the Northern Adelaide region.
The location of the College was selected due to its proximity to the industrial hub of Elizabeth, the activity in the building and construction industry stretching from Adelaide's inner northern suburbs to the Barossa Valley and the growth in the defence industry located around Adelaide’s north west.
The College started classes at temporary facilities at Davoren Park with 100 students engaged in five trades:
- Building & Construction
- Commercial Cookery
- Metals & Engineering
In May 2008, operations moved to the $12 million purpose-built specialist facility at Hooke Road, Elizabeth West.
In July 2009, the College governance and ownership passed to the South Australian Commission for Catholic Schools on behalf of the Archdiocese of Adelaide and the College began a new journey as St Patrick's Technical College within Catholic Education South Australia.
In 2010 the College expanded its trade offerings to include Hairdressing and Plumbing and in 2011 introduced a tertiary pathway through an Applied Engineering program.
