“Life stage: Super (1990) proposed five life stages (Growth, or childhood; Exploration, or adolescence; Establishment, or young adulthood; Maintenance, or middle adulthood; and Decline, or old age) through which individuals progress over their lives. Super (1990) also posits substages for stages. Two measures developed to assess an individual’s progress through these stages include the Career Adjustment and Development Inventory (CADI; Crites, 1982) and the Adult Career Concerns Inventory (ACCI; Super, Thompson, & Lindeman, 1988). Closely related to Super’s concept of career pattern” (Carson, n.d.)

Related: Stages of a Man’s Life: Levinson’s model contains five main stages: the pre-adulthood stage (age 0 – 22), the early adulthood stage (age 17 – 45), the middle adult stage (age 40 – 65), the late adulthood stage (age 60 – 85), and the late late adult stage (age 80 plus.) “The shift from one era to the next is a massive developmental step and require a transitional period of several years.”(Levinson, 1978.) This model is discussed in relation to women in The Seasons of a Woman’s Life.
