Post-schooling off-the-job training (Off-JT) is common, but little is known about how recent benefits vary across levels of formal education. Using a fixed-effects difference-in-differences regression coupled with the National Longitudinal Study of Youth 1997 data, I estimate how Off-JT certificate completion impacts employment and real (2014) annual income. Among those with a college degree, there is a significant increase in annual income. The total effect when individual-specific linear time trends are included ranges from $4,803.6 to $5,844.7. In contrast, for those with less than a college degree there is no significant change in income, despite a significant increase in employment. This is likely due to the small impact on hours worked for those without a college degree (an increase of 27 hours over the year, on average). The results suggest that the recent returns to Off-JT certificate completion depend on the formal level of education acquired prior to Off-JT.
