Please check - the teacher does not have a pay review after 31 August of the year prior to census day.
At the start of each academic year, all staff members should have a pay review.
This date needs to be added to their staff Contract section. You can see how to do this here: How do I add pay review dates?
However, if you don’t have the date you can still submit the census as this is only a query.
You will need to provide an explanation when uploading your census about why this wasn’t resolved.
