katie is a bright 1st grader who began reading at age 3. she is currently being tested for the gate program. she is also diagnosed with high functioning autism (hfa). she seems to enjoy school and she smiles often. other children have expressed interest in playing with her at recess. she likes playing with others, but at times she begins to take off her clothing. this stigmatizing behavior is degrading to her, interferes with developing friendships, and could escalate to undergarments if not correct. it’s caused quite a stir on the playground and among parents. her teacher wants to address the issue immediately, so she takes data and identifies the target behavior.
