For advanced workshops, I find it helpful when they address practical strategies re how to deal with common issues for gifted kids. For example, some of the best "advanced" seminars that I have attended have addressed coping with anxiety, dealing with perfectionism and managing executive function challenges. Also, remind the speaker NOT to waste half the lecture on "gifted 101." If it is an advanced seminar, people already know this stuff and want to spend time on what to do to help their kid get over the speed bumps.
