That's why I said earlier that TKD has a set curriculum for each belt instead of a rotating curriculum. For example: Our white and yellow belts learn front kick, roundhouse kick, side kick, and axe kick. The first three kicks we expect to be around waist high (although we take into account the person's condition if they can't), and we expect them to be done slowly, weakly, and with mediocre form. Axe kicks we expect to be a stretching kick (not a true axe kick). Purple and orange belts learn back kick, and learn basic footwork combined with the front kick, roundhouse kick, and side kick. At this point, we expect good form and mediocre speed and power from the basic kicks. Back kicks are usually slow, weak, and have bad form (we're more happy if they spin the right way and kick with the right foot). Axe kicks actually become downward kicks now. Green belts start learning tornado kick, hook kick, and spin hook kick. We expect the tornado kick to be done step-by-step, the hook kick to be decent, and the spin hook kick is just atrocious. Basic kicks should be done with good speed and power, and at this point should have great form. We introduce more advanced footwork like skipping kicks, repeating kicks on the same leg, and double kicks. Blue belts don't really have any new kicks, but we expect the tornado kick to be done well, and the spin hook kick to be done smoothly. Basic kicks are done in longer, more difficult combinations. Red belts are expected to really perfect the functional kicks (black belts get more into the fancy show-off kicks). This is when we make the spin hook look good, for example. So a beginner isn't going to have to worry about a spin hook kick, because we don't even teach it until green belt.
