Email John Marshall if you are interested in taking this course.

Faculty: Thomas J. Willis, Ph.D.

This advanced, competency-based training practicum is appropriate for psychologists, behavioral consultants, resource specialists and other qualified professionals charged with assessing individuals who exhibit severe and challenging behavior and with designing positive behavior support plans based on a functional analysis of behavior. Previous participants have attended from Australia, Canada, Great Britain, Greece, Hong Kong, Ireland, Malta, New Zealand, Norway, Spain, Sweden and the U.S.

We invite all behavioral analysts, behavioral consultants, psychologists and other professionals charged with the design and implementation positive behavioral support plans to consider this world-class training event.

Participants in this practicum will conduct a Comprehensive Functional Assessment on focus person in their caseload. They will submit their assessment report to Dr. Willis who will provide feedback on the report. The participant will then write a person-centered positive behavior support plan. After receiving feedback on the plan, the participant will implement the plan under the supervision and tutelage of Dr. Willis. During the final feedback session, the class will review progress and make recommendations for the future implementation of the plan. Thus, in addition to the participant improving their clinical skills, a focus person in their caseload will also receive the benefits of a fully developed and implemented positive behavior support plan.

This is an Online Course. You do not have to travel in order to participate! All you need is a high-speed Internet connection, a webcam and a microphone!

Fee: $3000 per person USD, we can invoice in your local currency.
