Cost-effectiveness analysis (Table 6) totaling SI leaders', coordinators', trainers', and management time at €98,400 per quarter. The authors state these costs "are considered low for an educational intervention" and estimate €252 per student at full sessions and €154 with costs spread over quarters.

"Divided by the 255 students who were granted access to the SI sessions this amounts to a total cost of € 385.88 per student (Table 6). These costs per student are considered low for an educational intervention (Kraft, 2020)."
