Responding to a request from the Education and Home Affairs Scrutiny panel to introduce the cuts gradually if they are approved, Deputy James Reed said any reductions would be phased in to minimise the impact on parents.
Fee-paying schools have also been asked to provide the minister with details of what support is available for parents with more than one child at the same school, and how they manage cases of financial hardship.
From there, he said, a decision will be made on whether that support is sufficient to maintain access to fee-paying schools.
