After completing his secondary schooling at Gore High School, Callum successfully applied to undertake the full year engineering pre apprenticeship course at the Southern Institute of Technology.

During the pre apprenticeship course students cover various health and safety requirements including first aid, safe use of hand tools and safe use of power tools all of which enables them to be safer in the workplace. They are also trained in the Level 2 unit standard requirements of their apprenticeship qualification which enables the student to be more useful in the workplace from the very beginning of their apprenticeship.

At the completion of the course Callum was offered a Modern Apprenticeship with Custom Build in Gore. Every Modern Apprentice has their own Modern Apprentice Coordinator who works with them to develop an individual Training Plan for them. The Coordinator visits them quarterly throughout the year to ensure that the tasks set for that quarter have been achieved, and to set tasks for the coming quarter. The Coordinator guides the apprentice through their apprenticeship.
