When I learned to fly, spinning was on the syllabus and I remember being sent out to practice solo stalling and spinning as a student. Spinning used to be a hurdle for some student pilots when I became an instructor, particularly as just about all modern light aircraft were designed not to spin. To keep them spinning you had to hold in pro-spin rudder or they would just recover of their own accord! Eventually that part of the syllabus, introduced before WWII when aircraft certainly did spin with a little encouragement was rightly dropped. During all my training for my CPL, I never had to spin an aircraft or recover from same, and I doubt you will ever have to. The only sort of spinning I wouldn't like to get involved with is an inverted one as I have had no training in this recovery, but this is only a possibility if you badly mishandle a very aerobatic type of aircraft.
