In 2016, Finland was a partner in a study which looked at how well the aims of the programme had been achieved in schools' professional development projects and what impact they had had on school communities. The survey Impact and Sustainability of the Erasmus+ Programme Key Action 1 Mobility Projects for School Education Staff was coordinated by the Erasmus+ National Agency of Lithuania, and the other partners were Poland, Germany and Estonia.

The focus of the first research carried out in 2016 was the impact and sustainability of the Erasmus+ Programme Key Action 1 (KA1) right after the completion of the projects, while this follow-up research performed in the year 2019 (two years after the end of the projects) focuses on the analysis of the long-term impact of the mobility.
