Yes. All GTAs will receive a King's affiliate email account once they accept their first assignment on King's Teachers. 

You will be sent registration details by King's IT via email to the account you registered with on King's Teachers. This can take up to 5 working days but is often sooner. Once you have registered for IT access, you should speak to King's IT Help Desk (8888@kcl.ac.uk) about your account if you have any queries. 

Affiliate accounts are a  standard way that King’s provides staff with a King's email account and IT access.
