Human Factors
I was providing an instructional flight in Aircraft X and we were on a night cross-country flight to ZZZ from ZZZ1. My student made calls on ZZZ CTAF 15 NM; 10 NM; 5 NM; and once established on the 45 entry left downwind for Runway XX (active runway). No calls were made from the other aircraft; Aircraft Y; until we were on the final and he then said he was taking Runway XX and said he would expedite. Once; on short final; we could tell there was no way we would have safe distance between us and had just begin his takeoff roll; so we decided to take evasive action and go around; climbing to the right of the runway (left traffic). We continued our flight as normal with no other concerns; and Aircraft Y apologized to us several times and they seemed to be fine as well and continued their flight. I'm happy the outcome ended well for all of us; and it was a good learning lesson.
Flight Instructor on final approach to a non-towered airport reported initiating a go around due to a departing aircraft on the runway.
