TREE (Transitions from Education to Employment) is a nation-wide longitudinal multi-cohort study following up young people after their completion of compulsory school. The follow-up study analyses the school leavers' post-compulsory pathways through education and into the labour market and adult life. The TREE study's objective is to gain in-depth scientific knowledge on school-to-work transitions in Switzerland, thereby identifying factors which encourage or hamper their success.
A first sample of several thousand school leavers has been followed up since the year 2000. A second sample of similar size has been launched in 2016.
The TREE study is mainly funded by the Swiss National Science Foundation (SNF).
