The University has strict rules about how much paid employment a full-time graduate student is permitted to undertake. Note that it is NOT possible to fund your studies by 'working through' your degree, except as set out in Sections 2 and 3 below. The rules regarding working while studying are set out on the University's website
1 Teaching undergraduates
Within these constraints, the Graduate School encourages graduate students to undertake teaching or lab demonstrating relevant to their studies up to a maximum of six hours a week. Not all students will have the opportunity to do this, however, as availability is limited. We do not offer Teaching Assistantships. Training is strongly recommended for graduate students wishing to make themselves available to teach undergraduate students.
2 Members of University Staff taking research degrees
Staff engaged in full-time research in the University as Research Assistants may wish to explore the possibility of applying for admission to the University as a full-time research student. This may be possible where the candidate: holds the minimum academic qualifications required; has the strong support of his or her principal investigator and head of department; is employed for at least the minimum duration of the research degree; and the project intended for the degree maps exactly onto the research carried out in the employment (such that no more than 6 hours per week would be spent on work other than the degree). Where the research projects are less than fully matched, candidates may seek to register for a part-time research degree, providing they are employed for the minimum research period of the degree sought. Staff employed by the University who register for a research degree are normally eligible to pay the Staff Fee.
3 Other employed persons wishing to register for a research degree
Researchers in institutes and local companies may apply for a part-time research degree, but are not eligible for the Staff Fee rate. Clinicians undertaking training in and around Cambridge may undertake a full-time or part-time degree or diploma via the Clinical Academic Training Programme.
