Our DC was tested as gifted in early primary (live abroad and where we are, this is essentially IQ tested). Tested as highly but not quite profoundly gifted. Did well in a Montessori through age 6 but we moved them to mainstream school for the first proper year here (6 turning 7).
It’s not going great, a fair number of behavior issues. DC has been assessed for behavioral disorders and has none (not ASD, ADHD etc). Likely source of the behavior is frustration with basic work, lack of boundaries but the school (no consequences for the behavior) and emotional intensity common in gifted kids. The school district does 3x yearly assessments to understand where kids are academically and DC tested not only highest in the year, but apparently with a very significant gap between them and next child which tracks with earlier assessment (ie, it’s not just one test placing them there). It would place them as average for a child 4 years older.
Our school options are, try to make mainstream work, go back to Montessori, try to go privately to a gifted specific school locally (but places are extremely limited) or go for the district gifted specific school. District school is mainly focused on acceleration and not great for social emotional. Curious about experiences of parents of similar children in mainstream. Did it ever work? And respectfully not looking for parents of bright kids, looking for experiences from parents of kids who are consistent outliers.
