I moved my 15 y/o Son to the left seat of the Warrior. My CFII has been expired for a while, but I thought he could get a little headstart. His take-offs are fine, still working up to landings. Most of his flying is at altitude, maneuvers & the straight & level stuff. We usually go over an item or 2 on each event/flight. I was surprised with his 'pushback' with my instructing him to taxi on centerline. Of course it takes a bit to get the feel for steering & all. Besides the safety & clearance aspect of centerline taxi I think it shows you have your head in the game. Am I asking to much? We've only had a handful of flights with him left seat though, just setting the bar.
