  1. Tables 3a–c show the mean years of experience in the treatment and the control group, separately by age groups. The third column shows the differences between the two groups at each age with t-statistics in the parentheses. 3 a presents the data of the whole sample, 3b for those who have at most a lower secondary qualification, and 3c for those with an upper secondary qualification
