CTC currently offers the Graduate Certificate in Teaching Religious Education at three off-site locations: Werribee, Craigieburn and Hong Kong.  This course provides an opportunity for students to develop and deepen their understanding of theology, sacred scripture, sacramental life, and religious education. The Certificate enables students to prepare, implement and evaluate programs of religious education.  It fulfils the requirements of the Catholic Education Commission of Victoria Policy 1.7 Accreditation to Teach Religious Education in a Catholic School for teachers who already meet the VIT requirements for teacher registration.

From 2014 to 2016, CTC offered pastoral ministry formation at Shepparton through the Graduate Certificate in Theology, in collaboration with the Diocese of Sandhurst.

Previous outreach programs included:

In 1995, the Master, Dr Mark Coleridge, arranged for two units each semester to be made available at Catholic Co-educational College at Sydenham, to accommodate students from the western suburbs.  This continued for four years.  With the transfer of CTC from Clayton to East Melbourne, and with much greater accessibiity of public transport, the venture concluded in 1998.

In 1987, on the initiative of the Master, Dr Norman Ford sdb, CTC offered a Bachelor of Theology unit in each semester at St Paul's College, Traralgon.  During the nine years of its operation, this initiative provided the regional community of Gippsland with the chance of completing two-thirds of the degree. Many completed the final units of the degree at Clayton.
