Stages of group development

Every group you ever lead will move through predictable weather: an awkward polite start, a thunderstorm of conflict, a settling calm, and finally real work. Examiners love this because the stages are named, ordered, and each one hands the leader a specific job.

The classic model is Tuckman's five stages: Forming, Storming, Norming, Performing, Adjourning (mnemonic: Fun Sheep Never Poop Alone). In Forming, members are anxious, dependent, and testing whether the group is safe. In Storming, conflict erupts — challenges to the leader, jockeying for control, resistance. In Norming, cohesion forms and members agree on how they'll operate. In Performing, the group does its productive work with intimacy and trust. In Adjourning (Tuckman added this in 1977), members grieve and consolidate gains before ending.

Corey's parallel stages map onto the same arc: Initial (orientation, exploration — like forming), Transition (anxiety, defensiveness, conflict, struggle for control — like storming), Working (cohesion and productive action — like norming/performing combined), and Final/Termination (consolidating learning, saying goodbye — like adjourning).

The testable heart of this topic is stage-matched leader tasks. Early (forming/initial), the leader builds trust, models, clarifies norms, and reduces anxiety. During the storm (storming/transition), the leader does not flee the conflict — they acknowledge it, address resistance directly, and help members work through it; conflict here is normal and necessary. In norming/working, the leader steps back, encourages member-to-member feedback, and lets the group do the work. At adjourning/termination, the leader helps members review gains, process feelings about ending, and plan for transfer of learning.

Clinical Pearl: Storming (Corey's Transition) is the make-or-break stage examiners test most — the correct leader move is to address and work through conflict, not smooth it over or avoid it, because unresolved transition blocks the group from ever reaching the working stage.
