Scenario: An observation conducted at Leo’s elementary school revealed that majority of his biting occurs when instructional demands are placed. Specifically, biting tends to occur most often when he is presented with reading materials. However, Leo also bites when presented with other work demands, such as math or writing.

Leo also elopes to his desk or restroom to escape work and other aversive activities. The following observation was conducted during English Language Arts at Leo’s school on 5/3/21 from 8:00-8:50am.

For Part 2 of this practical assignment, please review the following indirect and direct assessment results for Annie’s challenging behavior. Annie is a five-year-old girl diagnosed with autism spectrum disorder. She loves playing on the iPad, music, ocean animals, and swimming. Annie’s family has difficulty taking her into the community due to her exhibiting challenging behaviors, described as being “impatient”, running away or grabbing items that aren’t hers. She also has difficulty waiting in line and being told “no”.
