Hi Amy,
Your Interim Profile is due to be submitted at some point in November/December. Local authorities usually set their own deadline for when they want the profiles submitted to them, which is why there is not one definitive deadline for all probationers.
If your Supporter/Mentor/Headteacher does not know when your profile is to be completed and submitted, then you should contact your local authority Probation Manager. You should be able to find the contact details for your Probation Manager on the Probationer Teacher Scotland website, on the following page:

Hope this helps!
