If you are enrolled at a Higher Education or a Higher Education/Further Education (HE/FE) Institution in the UK and wish to study, do a work placement or be a language assistant for between three months and an academic year in an EU, EEA, or candidate country you may be able to participate in the Erasmus Programme. Students from all subject-areas can participate, from art to zoology, biology to psychology. However, please check with your home institution as not all institutions offer Erasmus for all subjects – so do your homework first. Postgraduate students can also take part in Erasmus, provided they have not already exceeded their grant quota.
