Assessing functional relations: The utility of the standard celeration chart.

The discovery of functional relationships among variables is critical to the behavior scientist’s goal of prediction and influence of behavior. Precision teachers’ efforts are bolstered by their ability to illuminate functional relations between tool skills (e.g., letter sound fluency) and composite repertoires (e.g., oral reading fluency) using the Standard Celeration Chart (SCC). Ongoing assessment of composite repertoires in the context of tool skill interventions permits data-based decision making for optimal acquisition rates at the composite level. In this report, data obtained from learners enrolled in our handwriting curriculum illustrate the SCC’s role in identifying and capitalizing on these functional relations.
