A group has reached the "working" stage of development. Which model describes group development stages?

• A. Tuckman’s stages
• B. Forming, Storming, Norming, Performing
• C. Linear progress model
• D. Stages of group therapy by Yalom

Answer: (B)

Group development follows a sequence described by Bruce Tuckman. When a group reaches the working stage, it is in the Performing phase, where members collaborate effectively, roles are clear, communication is open, and tasks are completed toward the group’s goals. Tuckman’s model lays out four stages: Forming, Storming, Norming, and Performing, with Performing being the working stage. So the best answer is the one that lists these four stages, since it exactly maps to how groups develop and reach high-functioning collaboration. Other frameworks either describe different concepts or focus on therapy-specific dynamics, not the general four-stage progression.
