The Middle School was known as ‘Intermediate School’ until and has been in operation in various forms at Hutchins since , catering to a mix of boys in Years 6, 7 and 8. In a new Intermediate School, consisting entirely of 70 first year secondary students, opened in the former Sub-Primary Block at Sandy Bay under F J Williams (1960–69).

This ‘experimental venture’ grew to include the second-year boys. After a temporary return to Macquarie Street, by the Middle School was in full operation at Sandy Bay. It had doubled in size and provided a broad range of subjects.

Under long-serving Master of Middle School, John Millington (1970–95), a new Middle School consisting of classrooms, audio-visual studio, performance space, offices and allied facilities, opened in . A Year 6–9 review conducted in led to the introduction of a K–8 timetable, placing Middle School as a self-contained unit within a Lower School complex.

The Middle School was completely rebuilt in , with the construction of a new building adjoining the Auditorium creating light, airy and open classrooms and offices surrounding an attractive Megaquad for outdoor activities.

Moving from primary school into secondary school should be… challenging and rewarding, maximising learning and growth. What we do allows students to learn but also develop character.
