The government will cover the cost of schools in England appealing against A-level and GCSE grades, the BBC understands.
It comes amid an ongoing row after 280,000 A-level students had their marks downgraded.
Ministers are also expected to set up a “gold command” taskforce, led by Schools Minister Nick Gibb, to oversee the appeals process.
The government previously said it wants the process to conclude by 7 September.
Speaking to the Times, Education Secretary Gavin Williamson said the government would cover the fees in a bid to ensure that head teachers were not deterred from making appeals.
Earlier, Labour called on ministers to act immediately to sort out an “exams fiasco” in England and stop thousands of A-level students being “betrayed”.
And some Tory MPs have challenged the fairness of how grades have been decided.
BBC News political correspondent Helen Catt said having “an efficient and effective” appeals process “is going to be really important in making sure more Tories don’t join them”.
