Why didn’t the Weasleys qualify for the school fund?

Sorry if this has been asked already but I was just wondering :)

In CoS, when Mrs Weasley empties their vault, there is only one galleon. We know from PS that a wand costs seven galleons. Ginny needed a wand, robes, a cauldron and all her books, not to mention Ron, Fred, George and Percy’s things and the Lockhart books too. Surely this would qualify them for the school fund as they clearly can’t afford everything.

They are a family of seven (not including Bill and Charlie) living off of Mr Weasley’s one pay check. Take away the money for necessities (like food) and they’re left with nearly nothing for anything else, let alone expensive school equipment. Compare this to Tom Riddle, who qualified, who has absolutely no money to spend on school things. I’d say the Weasley’s are pretty close to having nothing to spend.

If they don’t qualify, how poor do you have to be to qualify?

I’d just like to know anyone’s thoughts as I’d have thought if anyone would qualify for the school fund, it would be the Weasley’s :)
