ESN is operating on three levels:
- local (like ESN PW),
- National (like ESN Poland)
The main goal of Erasmus Student Network is to support student exchanges at any level, therefore every student coming for an exchange at a university where an ESN section is present is warmly welcomed, receives all the information he/she needs and gets rapidly involved in the local students' life. To achieve that goal ESN organizes a number of activities and projects.
