How much time must I devote to my doctoral thesis within the scope of a Doc.CH grant?

In principle, the work-time percentage is 100% and you must devote all of it to your doctoral thesis. Where there is good cause, the applicant's working hours may be reduced, but – except during very short periods – should never fall below 80%. Working hours corresponding to less than 100% may be applied for if one of the two following reasons is provided in the application: care duties or fulfilment of activities that serve to qualify them for a scientific career (e.g. teaching, training or continuing education in their field). Applicants may also change from full-time to part-time work during the funding period of a Doc.CH grant for the stated reasons. Such changes must be approved by the SNSF.
