Narrative:

[We] executed an off airport landing due to fuel exhaustion from the fuel selector valve being inadvertently turned off by the student pilot. The fuel selector valve had no detent to prevent such a situation. Engine power was lost and a decision to execute an off airport landing was made as the airport was beyond glide distance for the aircraft. Executed an uneventful off airport landing and that is when I noted the fuel selector valve was in the off position after securing the aircraft. No attempt to restart on my part because the lack of altitude and confirmed landing site.student pilots accustomed to a previous flown cherokee with the detent feature that wasn't found in this model; my complacency believing that the student knew the fuel selector positions. My inaction to verify the selector valve was in the correct position after the switch.
