Public or Open Self

• The teachers knowledge of her teaching behaviors
  and other aspects of professional practice that
  correspond to the supervisors knowledge
• The area in which communication occurs most
  effectively and where the teacher is least likely
  to be defensive
• Broaden or enlarge this cell with the teacher

4
Hidden or Secret Self

• The teacher knows aspects about her teaching
  behavior and professional practice that the
  supervisor does not know.
• The teacher tends to conceal these for fear that
  the supervisor may use them to punish, hurt, or
  exploit.
• This cell demonstrates the importance of a
  climate of trust and credibility.

5
Blind Self

• The supervisor knows about aspects of the
  teachers behaviors and professional practice of
  which the teacher is unaware.
• This cell size is reduced as the clinical
  supervision develops and matures.

6
Undiscovered Self

• Neither the teacher nor the supervisor know all
  the potential for the teachers behavior and
  professional practice.
• The size of this cell reduces as the clinical
  process develops.
