How Long Is Too Long (HLITL) is a project looking into the length of Erasmus mobilities. 

There are many types of mobility: long-term, short term, blended mobility and others. In the preparations for the post-2020 Erasmus Programme, there are some discussions on whether or not certain types of mobility should be given a bigger focus than what is currently the case. This project will look into the different options that are out there, get statistics and provide recommendations for what works and what does not work.

The project is coordinated by Université de Versailles Saint-Quentin-en-Yvelines in France
