What are T-groups?
1. A T-group meeting does not have an explicit agenda, structure, or expressed goal. 
2. Under the guidance of a facilitator, the participants are encouraged to share emotional reactions (for example, anger, fear, warmth, or envy) that arise in response to their fellow participants’ actions and statements.
3. The emphasis is on sharing emotions, as opposed to judgments or conclusions.
4. In this way, T-group participants can learn how their words and actions trigger emotional responses in the people they communicate with.
