My PG son went through this @ K. We went with a traditional secular all-day Kindergarten. We informed the teacher of his abilities ( 4 years old could do multi/divis/fractions and reading early-chapter book ( Magic School Bus/Tree House, etc ..)).
We provided her with materials he could do if he was bored and needed to be separated from the other children so he would not be a distraction.
It didn't work out, the teacher really wanted to mold our boy into something he wasn't and it bit her in the butt as he made sure he would make every child miserable until she focused on them and left him alone.
Lots of calls to the office with the final days being told hewas not welcome there any more.
*shrug*
We decided then that acceleration was the only choice for him. We found a Montessori school that was very accepting and allowed our son to go as fast as he wanted, provided he did all the work required like other children in his grade and that his scores were high.
He is 7 now and in 7th grade and the behavior issues have mostly disappeared now that he is challenged all through the day, leaving no time for him to bet bored and into trouble.
