Tables 2a–c show the mean age when treated and control group members started their first regular job, separately by age groups. The third column shows the differences between the two groups at each age with t-statistics in the parentheses. 2a presents the data of the whole sample, Table 2b for those who have at most a lower secondary qualification, and 2c for those with an upper secondary qualification
