Janet is a BCBA-D who is consulting in a high school life skills classroom. She has recently suggested an intervention for a student with academic deficits. After a careful assessment, she has determined that the academic deficits are the result of a skill deficit as opposed to a performance deficit. She plans to train the teacher to use two academic interventions. The first will address handwriting and the second will address fluency with single-digit multiplication.
