In some areas of the country, refresher courses are offered infrequently. Can an individual applying for recertification lead-based paint activity discipline re-take an initial course instead of taking a refresher course?

Answer: Yes. Workers, Supervisors, and Inspectors can simply re-take the initial course(s) for their discipline(s). The situation is somewhat different for Project Designers and Risk Assessors. During the course of initial certification Project Designers must take both the Supervisor course and the Project Designer course. Likewise, a Risk Assessor must take both the Inspector course and the Risk Assessor course. In order to ensure that Project Designers and Risk Assessors receive refresher training in the full range of subject matter relevant to their expertise, they would have to retake all of the courses that were required for their initial certification. Therefore, when taking initial courses in lieu of refresher courses, Project Designers would need to re-take both the Supervisor and Project Designer initial courses and Risk Assessors would need to re-take both the Inspector and Risk Assessor initial courses.
