Forms and stances obviously are. But that's usually about 5-10 minutes of class time.
Punching in forms is a bit different than punching outside of forms. For example, in forms we typically use a static front stance, or shift from back stance to front stance. We also do punches that are not covered in the forms. And when we do punches...it's usually for about 3-5 minutes.
Kicks are barely a part of the Taekwondo forms. The type of footwork you would use in TKD (such as sliding kicks, skipping kicks, drag kicks, and lateral movement) aren't really part of the forms, either.
We don't teach any forms that include 540 kicks, kip ups, and butterfly jumps.
At my school we have the Master, his wife, and me as instructors. Everyone else who helps out (even the couple that are higher rank than me) are assistant instructors. I'm not the CI, but as far as instructors go, I'm pretty high up on the list. Now, I'm not going to pretend to be anywhere near as good a martial artist or instructor as my Master and I still have a ton to learn on both fronts. But I have a good rapport with the students and their parents, and I'd probably get enough students to show up that it would be worth my time.
And the less that show up, the better for those that do!
Definitely not the case at my school. There is a TON to learn for each belt test, which means the majority of class time ends up spent on the curriculum. As a result, there isn't a whole lot of time to focus on any one thing. It also can cause issues trying to learn some things when we don't go over them much in class. When I first joined, we mostly had 1st degree black belts (probably 90% of our black belts) and the 2nd degree black belts felt frustrated that we spent 95% of the class time on 1st degree stuff.
It really sounds like you have your belt-to-belt wagon load too heavy. It sounds like it would be too easy to gloss over something just to get "ready" for testing.
