Remuneration Rates for GTA at NHLI

Although the College’s employment policy states that full time students should not work more than 10-15 hours per week, the Graduate School recommends that GTAs should not teach more than 6 hours per week.  However, we recognise that GTAs may some times be involved in teaching which only lasts for a short period of time, but exceed the weekly limited such as fieldwork, lab weeks etc. Tier 4 students are reminded that they are legally not allowed to work more than twenty hours per week.

More information on cutoff and payroll dates can be found here


Teaching opportunities are distributed via email when available, along with instructions on how to sign up and other information relevant to the role (e.g. role requirements, key dates).  The College requires that any doctoral student wishing to undertake GTA work must have permission from their supervisor(s) prior to teaching. 

GTAs must also register with the College as casual workers for remuneration. This will be organised with the NHLI Education Team, prior to approved GTA work. 

Please contact Rachel Breen (r.breen@imperial.ac.uk) regarding any NHLI GTA queries.
