Mr Rumble said he had been proud of the work he had done, and he was "humbled and privileged" to receive the honour.
He had enjoyed his time in education, especially working with the at risk schools and helping them "gain a sense of positivity".
"It's extremely demanding but it's extremely rewarding to have success."
Mr Rumble originally left school early but was encouraged to return by a teacher who helped arrange a scholarship for him through to his final year.
"I have a lot to thank that teacher for. He was a bit of a role model and that is what I tried to do with the kids."
Mr Rumble said while the job had changed over the years, the kids had not.
"The best kids of today are equal to or better than the best kids of the past."
He said teaching, and in particular working as a principal, required a certain level of resilience - while it was an excellent career, it was also one that had ups and downs.
Mr Rumble said there were plenty of others in the field equally as deserving.
