"He got it cut short on the sides and he's got it just a little bit long on top. It's not even two centimetres long on top, not like it's a long fringe down to his nose or anything like that," she said.
"He's just got a boy's haircut, literally a boy's haircut and he's got a side part."
The woman claimed teachers told her it was against school policy for students to have hair shorter than a standard number two blade cut, and so she went to a barber for proof her son's hairdo was within the rules.
After returning with a note from the barber that said her son had a number two cut, "but it could look shorter because he has fine hair", it was agreed the boy could go back into class but "he has to wear a hat on his head all day long".
Sandra said the justification for requirement of a hat was that the short haircut "may offend".
"How can that offend anyone? He's got to wear a hat now," she said.
"I said 'you're discriminating against my child'. It's just wrong."
In an interview with Seven News, Jake himself said he thought the school's actions were "stupid".
"I thought it was silly. I don't know why they stopped me for my hair, told me I had to go home. I think it was stupid," he said.
Since Sandra's on-air rant, Facebook users have been sharing posts about the interview, overwhelmingly in support of the student and his disgruntled mother.
Comments criticising the school had been posted to the school's Facebook page, but appear to have been removed.
