The cost to the host organization of a group visit is emphasized, as it is not insignificant. Hosts can expect a maximum of 8 students and possibly one adult to visit for the day. Visits usually last about 4 hours, however the host determines the length of the visit based on the agenda they have planned. The host is asked to commit engineers to accompany students during visits to project sites. Usually two to five engineers of the host are involved, and a meal is often provided.
Conversation seems to flow better when accompanied by food in an informal atmosphere.
Each apprentice completes an evaluation of each visit. The evaluation includes names of engineers met, most interesting and least interesting activities and the most educational aspects of the visit. These reports are used to shape future visits. Three workplace visits are usually arranged for each group. They are spread out, with no more than one visit a month.
