Tiers

Many events use tiers as a way to penalize teams breaking event rules without resorting to disqualification. The default tier is Tier 1, for teams that have not violated any event rules. The event rules typically specify that teams breaking certain rules are ranked in lower Tiers - currently extending at most to Tier 4 in some events. In the past, various infractions involved differing levels of penalty, soemtiems with a many as eight tiers. This process was simplified to involve a smaller number of tiers during the early 2000s. The word is frequently used as a verb; for example, referring to a team as having "been tier 3'd for violating Construction Parameters."
