What are the subdivisions of adolescence?

• A. Early adolescence (11-14), middle adolescence (15-18), late adolescence (19-22), and emerging adulthood (22+)
• B. Early adolescence (7-10) and middle adolescence (11-14).
• C. Subdivisions are defined solely by social roles.
• D. There is no subdivision within adolescence.

Answer: (A)

Development unfolds in stages that reflect changing physical, cognitive, and psychosocial tasks. Early adolescence, roughly ages 11–14, is dominated by puberty and rapid physical changes, with growing awareness of peers and the start of more abstract thinking alongside ongoing reliance on adults for guidance. In middle adolescence, about 15–18, identity exploration intensifies, autonomy becomes more important, and teens navigate more complex social roles, often with peaks in risk-taking as they test boundaries. Late adolescence, around 19–22, brings greater stability in self-perception and values, a stronger focus on future goals, and smoother transitions toward higher education, work, and independent living. Emerging adulthood, extending into the early to mid-20s (the option notes 22+), is viewed by many as a distinct period of ongoing exploration of love, work, and worldview, with continued development of independence before entering full adult roles.

That combination—early, middle, late adolescence plus emerging adulthood—captures how adolescence can be divided into meaningful phases that map onto these developmental transitions, which is why it’s the best answer.
