Guided by lessons learned from legal cases, this session provides a commonsense approach to untangling the web of laws and regulations surrounding the manifestation determination process. Learn the steps you need to take to make manifestation determination decisions that stick; who should be involved in making them; what information you must consider; whether an assessment should be completed; how to document and defend the decision; and more. The 31st National Institute was held May 2-5, 2010 in Orlando.
