ETF - Cohort-sequential longitudinal databases Evaluation through follow-up

The ETF database has its origin in longitudinal research projects started in 1961. From the beginning, the idea behind ETF has been to merge data collected by educational researchers with school administrative data and data from official registers relevant to educational achievement, choice, and attainment.

Initially the aim was to provide a basis for evaluation of the Swedish educational system by following individual students in their educational careers. Since many variables are available across cohorts it is possible to study the impact of changes within the educational system as well as in the Swedish society. 

Today a second aim of ETF is to support longitudinal research in different disciplinary areas in which information about background, aptitudes and achievements of individuals form interesting control and explanatory variables, for example in research aiming at causal inference. The second aim is becoming increasingly prominent, and the ETF database serves a large number of studies within different disciplinary fields, such as education, economics, medicine, psychology and sociology.
