Ministers have promised special schools will receive their share of additional funding after some councils seized previous cash boosts.
Schools Week investigations have revealed how cash-strapped local authorities kept millions of pounds in previous school funding rises.
While cash goes straight to mainstream schools, additional funding for special schools goes to councils as part of high needs funding.
Last month, Schools Week launched a campaign to ensure schools for the most vulnerable children were not “robbed” of their share of the £2 billion extra cash announced in the autumn statement.
The Department for Education said today that special schools would be “guaranteed” a funding boost from April next year.
