||Skier 's Challenges
- Upright - feet must be lower than head
- Inverted - elaborate somersaults and twists (most common type of aerials for junior competitors)
A series of bumps on a trail formed when skiers (once known as "hot-doggers") push the snow into mounds or piles as they execute short-radius turns, creating a bump field... usually groomed, but sometimes ungroomed to build-up bump to prevent skiers from gaining too much speed and getting out of control.
Time trial or qualification rounds where every competitor skis down the course, featuring naturally occurring terrain and manmade features like jumps, rollers, and banks. Starting simultaneously, the goal is to be one of the first two across the finish line and advance to the next round.
- Aerial skiing - Jump Takeoff (20%), Jump Form (50%) and Landing (30%). A degree of difficulty (DD) is then factored in for a total score and a cumulative score of two jumps.
- Moguls - Turns (50%), Speed (25%), Air (25%)
- Ski-Cross - (Highest scorer in final round wins)
- Turns - quality; deductions for technical mistakes
- Air - quality; height off the jump
- Time - time compared to course pace-time
