There are 2 ways in which you can track a student using their UPN number.
The first being - Using the search box at the top right hand side of the Dashboard - enter the UPN number here.
If the student is on roll within your school, their name will appear and you will be able to go to their profile by clicking on it.
Secondly - If the student is off roll, you are able to go to Reporting-Reports>Students (Blue Tab) and choose the Admissions and Leavers Report.
You then can choose the dates prior i.e. from 2018 till now, tick the Former students box only and tick the Departures box, then choose.
After creating the report, if you use your Control/Command key and the letter F, this will give you a search box at the top of the page, where you are able to enter the UPN number. If the student has left within this timescale they will appear highlighted in the report.
If the issue still persists for you, please do not hesitate to contact email@example.com or come on to Chat or phone. 01522 716049
