Third Tier

Corey deVos

Conventionally, a tier is just an arbitrary grouping of stages. Integral Theory often highlights three tiers: First Tier, which consists of the levels up to and including Green altitude; Second Tier, which consists of Teal and Turquoise altitude; and Third Tier, which includes all post-Turquoise levels of development (Indigo, Violet, Ultraviolet, and Clear Light).
