Prior work
This trial is based on or builds upon one or more prior RCTs.
During information evenings about the upcoming choice of tracks at the end of 6th grade, we will provide attendants with information on how strongly girls and boys adjust their aspirations for vocational trainings in the STEM fields when these aspirations are to be discussed with parents rather than staying confidential. We will analyze whether the provision of this information affects eventual track choices.

Experiment Characteristics

Sample size: planned number of clusters
10 schools
Sample size: planned number of observations
Between 900 and 1,100 students.

5 schools control, 5 schools additional information; around 450 students in control and 450 students in treatment "additional information".
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
Approximate based on assuming 900 students: - MDE overall: 7.96pp difference (from baseline around 20%) [for baseline of 30%: 8.9pp]. - MDE among female students: 11.52pp
