Why it works
Group contingencies are a class of behavior strategies in which a consequence, usually a reward, depends on the behavior of a group rather than solely on each individual, and they are among the better-evidenced tools for shifting whole-class behavior, with the Good Behavior Game in particular supported by decades of research including long-term benefits. Their power comes from harnessing peer influence, which in a classroom is enormous and usually works against the teacher, and turning it in a positive direction: when a group's reward depends on everyone meeting a behavior goal, students encourage and support one another's good behavior rather than egging on misbehavior. There are three types, and the distinction matters. In a dependent group contingency, the whole group earns the reward based on the behavior of one student or a few, which is the riskiest type and easy to misuse. In an independent group contingency, each student earns the reward based on their own behavior, with the same criterion for all, which is essentially individual contingencies applied class-wide. In an interdependent group contingency, the group earns the reward based on the group's collective behavior (everyone, or the class as a whole, meeting the goal), which is the type the Good Behavior Game uses and the one that most powerfully mobilizes positive peer support. Used well, interdependent group contingencies are efficient, build a positive class-wide climate, and recruit peers as allies in good behavior. But they can backfire badly if designed carelessly, and knowing the pitfalls is as important as knowing the technique. The central danger is the student who cannot or will not meet the goal becoming the target of peer resentment or hostility for costing everyone the reward, which is harmful and the opposite of the intent. Good design prevents this: set achievable goals so success is the norm; use team structures (several teams that can each win) rather than all-or-nothing whole-class stakes, so one struggling student does not doom everyone; build in ways that a student with genuine difficulty is supported rather than scapegoated, sometimes through individualized criteria within the group structure; keep the tone positive and game-like rather than punitive; and watch vigilantly for any peer pressure turning negative, intervening immediately if it does. The strategy also works best as one tool within a positive behavior approach, not as the whole system. The workshop helps teachers understand the three types, design an interdependent group contingency that mobilizes positive peer support, and build in the safeguards that keep it from turning peers against a struggling student.

The core activity: design a group contingency with safeguards
The heart of the session is designing an interdependent group contingency that mobilizes positive peer support without turning peers against a struggling student.
- Harness peer influence positively: when a group's reward depends on meeting a behavior goal, students support rather than egg on each other's behavior.
- Know the three types: dependent (riskiest), independent (individual criteria class-wide), and interdependent (the group's collective behavior, as in the Good Behavior Game).
- Design an interdependent contingency with achievable goals, team structures rather than all-or-nothing stakes, and a positive, game-like tone.
- Build in the safeguards: support struggling students rather than scapegoat them, sometimes with individualized criteria, and watch vigilantly for peer pressure turning negative.
Facilitator notes
- The scapegoating danger is the central risk; the student who cannot meet the goal must be supported, never made the target.
- Prefer interdependent contingencies with team structures over all-or-nothing whole-class stakes that one student can doom.
- Keep it positive and game-like, and use it as one tool within a positive behavior approach, not the whole system.
Adapt it
- Elementary: use the game-like Good Behavior Game format with teams and achievable, frequent wins.
- Secondary: keep the tone positive and the stakes team-based so no one student carries the whole class's reward.
- Any setting: watch for peer pressure turning negative and intervene immediately; support, never scapegoat, a struggling student.

Group Contingencies: positive peer support, safeguarded
Tie the reward to the group to mobilize peer support: design an interdependent contingency with achievable goals and teams, and safeguard against scapegoating.
- My whole-class behavior goal (achievable):
- The type and structure (interdependent, team-based):
- How I keep the tone positive and game-like:
- How I support, not scapegoat, a student who struggles to meet it:
- How I watch for and stop peer pressure turning negative:
Make it stick
Group contingencies work when designed to stay positive. Close by setting the follow-up:
- Name a check-in: are peers supporting each other and is no one being scapegoated?
- Bring one contingency and how the peer dynamic went.
- Keep watching for negative peer pressure; stop it immediately if it appears.
