Education Secretary Nicky Morgan said the inspectorate should be able to publish information about the performance of academy chains. It comes after months of wrangling between the department and Ofsted chief Sir Michael Wilshaw on the issue.
Sir Michael made repeated calls last year to be given explicit powers to inspect the head offices of academy chains, in the same way that Ofsted can look at local council children's services.
More than half of England's schools are now academies, and many are run by multi-academy trusts, some of which run tens of schools. But Mrs Morgan, and her predecessor Michael Gove, had argued that Ofsted did not need to be given additional rights to examine the overall management of these groups.
Setting out new rules for academy trust inspections in a letter, Mrs Morgan said that the watchdog should continue to conduct "batch" inspections of academies that are all run by the same trust.
She goes on to say that she would expect that Ofsted would meet with staff from multi-academy trusts shortly after inspections have taken place.
She said: "They should share and discuss the evidence already gathered and collect and consider further evidence to demonstrate the impact of the MAT's work with its academies.
“While the focus must remain on the academies that have been inspected, I agree the dialogue should include consideration of achievement and other relevant data for all of the MAT's academies.
"It should also consider the arrangements the MAT has made for the effective overseeing, challenge and support of individual academies. Inspectors would then be able to draw together the range of evidence and make a balanced assessment of the work of the chain with the academies inspected."
There will be no formal extension of Ofsted's inspection powers. Where there are concerns about performance, Ofsted has previously attempted to overcome the issue of Trust inspections by conducting inspections at a number of schools run by the same chain and then publishing its findings.
In total, it has issued critical letters to four different academy chains - the Academies Enterprise Trust (AET), School Partnership Trust Academies (SPTA), Kemnal Academies Trust (TKAT) and the E-ACT Trust - after inspecting some of their schools.
