Peace Corps brings in 8-9 of their volunteers from a province who have expressed interest in participating, and they bring the volunteer’s counterpart.
The counterpart is the person, usually chosen by the village committee when it applies for a volunteer to come, to be the point-person between the village and the volunteer. Usually this person is a teacher and the best English speaker in the village. But that doesn’t mean the counterpart can speak English in any meaningful way.
(I just learned that in this case the volunteer chose a counterpart who they think will be the best person for this workshop.)
