Concerning the eligible exchanges for the MSCA Staff Exchanges 2026:
- Secondments between EU member states and associated countries are eligible for funding (no 1/3 rule).
- Secondments from EU member states and associated countries to all third countries are eligible for funding.
- Secondments from low to middle income third countries to EU member states and associated countries are eligible for funding.
However,
- Secondments from participants from “Other Countries” (not in the List of Participating Countries in Horizon Europe) are not eligible for funding and therefore by default have to participate at their own cost
- Secondments between Third Countries are not eligible for funding.
Concerning the interdisciplinarity, it is not mandatory for the same-sector secondments in Europe. However, according to the update of the MSCA part of the Work Programme the applicants will be evaluated under the criterion 1.2 Excellence on the Soundness of the proposed approach to foster international, intersectoral and interdisciplinary collaborations.
In addition, there is a new eligibility condition (see p. 6 of the Guide for Applicants)
- Sectors: The consortium must include participating organisations from both academic and non-academic sectors.
To conclude, interdisciplinarity is not mandatory for the same-sector secondments in Europe, however, the international, intersectoral and interdisciplinary aspect of the proposal will be evaluated under the excellence criterion.
