Well goodness me, how bizarre things can be sometimes. I agree Betty Banana, that extreme behaviors are the ones most likely to be recorded and noted. In my school years there were many comments and notes recorded about my inconsistencies from one day to the next, and the very obvious changes in my output level. It is extremely doubtful that a single teacher of mine thought, for even a fleeting second "Oh, I wonder if this is a symptom of a dissociative disorder?" Goodness no, back in the 90s and in the the first decade of this century even they would have known very little about dissociative disorders other than what they might have heard in the media about MPD and false memory syndrome. If there had even been anyone around to educate teachers about dissociative disorders at that point the social climate was such that I doubt they would have believed it anyway.

Part of my work now is in schools and I doubt teachers would know much of anything about dissociative disorders even now, let alone what the symptoms look like. I will ask next time I go in to a school. Given that so many therapists still don't believe in DID I just can't imagine that teachers are educated about it or know what to look for or know to refer a child for an assessment for it!
