Description of Starting Cohort 4—Grade 9


Main Study 2010/11, Study Number A46/A47/A60/A61/B34


1 Master sample: Grade 9 students (panel start 2010)

1.1 Target persons: Grade 9 students attending regular schools

  • Sample: Stratified cluster sampling with the following selection stages: 1. Random sampling of regular schools at lower secondary level. We distinguish between five types of schools (grammar schools, middle secondary schools, lower secondary schools, comprehensive schools, and schools offering all tracks of secondary education except grammar school track). These school types serve as stratums from which the schools are drawn proportional to their number of classes. Through different sampling rates within the five stratums an oversampling of schools in which students are likely to change into vocational training is implemented. 2. Random selection of Grade 9 classes at the selected schools. Two Grade 9 classes, if the school has them, are selected. 3. All students of the selected classes are invited to participate in the study.

1.2 Target persons: Grade 9 students attending special schools

  • Sample: Cluster sampling with the following selection stages: 1. Selection of special schools by size-proportional random selection. 2. Selection of all students in Grade  9 within selected schools (= full sample survey of Grade 9).

1.3 Context persons: Parents

  • Definition: All parents of selected students are invited to participate.

1.4 Context persons: Teachers

  • Definition: All class, German, and mathematics teachers of the selected students are invited to participate

1.5 Context persons: School principals

  • Definition: All principals of the selected schools are invited to participate.
