At the school I teach at, we certainly make the student aware of Vtoss (V2) as the minimum speed to be flown in the event of an engine failure after t/o with runway remaining (you want to get the aircraft down on the remaining runway and maintain controllability). If no runway remaining, the 60 kt best glide speed is taught to be used. As for a normal take-off, very little emphasis on Vtoss as you practically accelerate through it as you become airborne.
Company policy precludes us from doing simulated EFATOs where there is sufficient runway for landing (unless from a safe height).
