There are four levels of invitational education: intentionally disinviting teachers who deliberately discourage students and never smile; unintentionally disinviting teachers who are oblivious to their negative behaviors; unintentionally inviting "natural teachers" who are liked but may not maximize learning; and intentionally inviting teachers who have an invitational philosophy and work to invite students through verbal comments, behaviors, environment and self-talk. The basis of being inviting is building relationships, and effective teachers are deliberately inviting across four areas.
