No, unfortunately the Local Authority will only have sight of clashes between yourselves and LA maintained schools, so if there is a clash between yourselves and another academy this would remain hidden from them.
As you will be aware unresolved clashes mean that the DfE will not fund the pupil/student at either establishment, so it is in your interest to resolve the issue with the other establishment, and check that it has been resolved in the COLLECT Website the following day.
The Duplicate reports for "same person different UPN" and "Same UPN different person" are available on the COLLECT website, and whilst we appreciate that the DfE issue a deadline for submitting your census, that deadline does include completion of resolving enrolment status clashes, and any other amendments the DfE request, this is why it is essential to have your Census submitted within a week of Census day to ensure no loss of funding is incurred.
We run these reports repeatedly throughout the census period, due to the late uploads or changes that can affect the reports in adverse ways. If census are uploaded late then this shortens the period in which resolutions need to take place. If there is no resolution by the time the census period shutters, then a school could miss out on funding.
