A new set of editions. Microsoft is replacing its current line-up with five editions: A0, A2, A3, A5 and A7. A0 is for pupils only. The others come in a staff version and a pupil version. Microsoft calls staff "faculty" in its documents.
Some free licences are ending. On 1 January 2028:
Storage is worked out differently. Today every school gets a large shared allowance of 100 TB before anything else is counted. That base allowance goes. Instead, your school's shared pool will be the total of what each licence adds: for example 4 GB for each A2 pupil and 50 GB for each A2 member of staff, up to 12 GB and 150 GB on A5 and A7. The free A0 adds nothing. For many schools the new pool will be smaller than today's. Extra storage can be bought in 10 TB packs.
Some licences gain new features. Every paid edition, for staff and pupils, will include Copilot Chat, Microsoft's AI chat tool, for eligible users, and a new Microsoft Classroom. The updated A3 staff licence adds email threat protection (Microsoft Defender for Office 365 Plan 1). The updated A5 staff licence adds more tools for managing school devices.
You can mix and match. Editions can be chosen person by person, and versions without Teams will be available. Some features only work inside Teams, so check what you would lose first.
Pricing. If you buy through Academic Volume Licensing (an EES, OVS-ES or School agreement), online services will have one price whatever your price level. Microsoft says list prices for existing staff suites with Teams will not change, but what you actually pay may change, depending on how you buy and your mix of licences. It has not published the new prices, and says renewing early to avoid the changes is not allowed.
The key is your renewal date, not the date on the calendar.
So a school that renews every September will see the pricing change in September 2027 and the storage change in September 2028. A school part way through a three-year agreement keeps its current arrangements until that agreement ends. If you are not sure when you renew, ask whoever sells you your licences, usually your IT provider.
One point to check carefully: Microsoft says a school whose agreement began before a cut-off date can keep using Office 365 A1 until that agreement ends, but its own pages give two different cut-off dates. Ask your partner which applies to you rather than assuming.
You need to plan now if any of these apply to you:
Can your pupils have the free A0? Only if every paid member of staff is on A2 or higher, and only for pupils who use Windows devices for their learning. Microsoft says a school can have up to 20 A0 pupil licences for each paid staff licence. Bear in mind A0 has no email or Teams, so it will not suit every pupil.
We have built a free check in Digital Confidence. Enter your licence numbers, how you buy and your renewal date, and it tells you which changes apply to you and when, who needs a new licence, whether the free A0 is open to you, and what happens to your storage. It links each result to the DfE digital and technology standards, and you do not need an account to use it.
