Mistakes are continuing to be uncovered in the Novopay saga, with school funding now taking a hit.
Thousands of teachers have been underpaid, overpaid, or not paid at all, since the system launched in August, and now a type of funding - which gives schools money based on how many teachers they have - is also being impacted.
A school principal, who wants to remain anonymous, told RadioLIVE it is a mess.
"For a school such as mine, it has been a $25,000 swing in that running total which is to our benefit, but I do know of other schools… that have gone from a credit to a negative."
The principal says trying to fix Novopay's mistakes has cost his school thousands of dollars in extra work.
