Can someone define the general cutoffs for MG, HG, and PG? I'm relatively new to this forum, and I often want to qualify my responses with the fact that my kids are MG or HG (not sure which) as opposed to PG. I feel I have a much different perspective and experience than posters with kids who are in a higher percentile, and in some instances, it makes sense to explain that. Our school-age DS qualifies for our local gifted schools based on his WPPSI-III testing last year, and for our district's HGT program (top 2%), but I don't know whether to characterize him as MG or HG in this forum.
