I'll bet there isn't any
one answer to that, Bostonian.
Probably because:
- underachievement is encouraged in those groups
- schools without any resources for G/T kids certainly won't go looking for them
- adults who could identify those children don't know to look (lacking understanding of what G/T traits actually look like)
- adults who could identify those children believe that GT children look like ________ (which is often more a mark of higher socioeconomic status than anything else)
- PARENTS can't/don't know how to advocate for those children (for a variety of reasons)
- cultural factors lead to a parental/familial reluctance for "identification" as gifted (or anything else)
- cultural pull against G/T push leads kids ot underachieve/mask very young in order to fit in
- proportion of 2e kids in that group is likely higher (due to environmental factors), and therefore G/T may be well-masked.
Take your pick-- any and all may be reasons why a child isn't identified.
