"We thought it reflected the culture of the school and our kids."
So the board included the attribute in its advertisement for the role.
"Our students want their new principal to be funny, friendly, caring, organised and 'like Batman'," the vacancy reads.
And they "definitely" intend to hold any applicant to that requirement, Clark said.
"We're only just in the advertising process at the moment, but we are thinking of asking the candidates to explain how much like Batman they are," she said.
"I think your approach to that question might tell you a lot about the person."
Other suggestions from the children were more in line with traditional qualities that staff and parents were looking for, she said.
"A lot of what they said was quite consistent with what the staff and the community had said, for example, organised, respectful, encourages fitness and sport, cares about learning."
Clarke added: "Two kids said 'has Northcote Primary School values', and that's important because that was something that our community and our staff said as well.
"Our school has very strong values and we want someone who lives those values."
No costume necessary though.
