Organisations implementing mobility activities should adhere to a common set of Erasmus quality standards, applicable for years 2021-2027. These standards have been set to ensure a sound mobility experience and beneficial learning outcomes for all participants, and to contribute to the achievement of the objectives of the Programme.
Eligible participants:
Invited experts can be any persons from another EU Member State or third country associated to the Programme, who can provide expertise and training relevant for the needs and objectives of the organisation that invites them.
Eligible venues:
The venue for invited experts and teachers in training is always the beneficiary organisation (including consortium members).
