If she was in once, then kicked out....I don't blame her for not wanting to go back.
Kids are cruel, they either don't know or don't care, why she was kicked out....they will make it because she wasn't smart enough.
While it's not the same thing, my son's preschool teacher said he needed to start kindergarten at 4 (he barely made the birthday cutoff by 12 days)....because he was bored. So we sent him off to kindergarten.
He then went to "Transition" that was for kids - primarily boys- who had gone to kindergarten, had learned too much in kindergarten to repeat it, but weren't mature enough for 1st grade. He's 28 and has never let me forget that we "held him back cause he 'flunked' kindergarten". He has an IQ in the upper 140's, is dyslexic and for years felt like he was 'stupid' because the other kids teased him about 'flunking' kindergarten....
The county school system no longer has Transition, and they encourage parents with children, particularly boys, with late birthdays...to hold the kids out of school another year. Simply because too many children...and many parents....interpreted it as "flunking kindergarten".
If your daughter will be in the same school as this year, with the same students and principal, and runs the risk of being last in -first out again....there is no way that I would put her through that.
Put her in art school or something after school where she can get something that she can't out of regular school and then get her in accelerated classes in HS.
