For MSCA-ITN, secondments are periods of research training with another beneficiary and/or a partner organisation (from the Consortium) in order to further enrich the training experience of the researchers. When on secondment, the ITN fellow continues to be paid by the recruiting beneficiary. The country correction coefficient used to calculate the living allowance does not change.

The costs of participation in the secondment cannot be paid by the fellow; the additional costs of the fellow, such as short term accommodation costs and travel costs can be covered by category Research, Training and Networking costs. In the case of a long-term secondment (e.g. more than 6 continuous months), the fellow should not pay double rents and could use the mobility allowance to pay it. Total secondments cannot exceed 30% of the recruitment duration.
