TREE - Transitions from Education to Employment, cohort 1

TREE (Transitions from Education to Employment) surveys post-compulsory educational and labour market pathways of school leavers in Switzerland, being the country’s first prospective longitudinal study of this type at national level. The project's first cohort (TREE1) is based on a sample of approximately 6,000 young people who participated in the PISA survey of the year 2000 and left compulsory school the same year. This sample has been followed up by means of seven survey panels at a yearly rhythm between 2001 and 2007 and two further survey panels in 2010 and 2014. A further panel wave is planned for 2019 (at average respondent's age 35). In 2016, the longitudinal observation of a second school leavers' cohort has started. With this extension to a multi-cohort design, Switzerland is among the few countries worldwide in which comparative inter-cohort analyses can be carried out.
