You have to do that .
You need to make sure that once she starts she is in all AP classes otherwise she will learn nothing .
I even forced the school to send my daughter to the jr college to take the classes they did not offer in AP. She ended up with a bunch of credits .
You have to do it now or home school
Mine went to regular school because my husband did not want her home schooled but I basically home schooled her anyway.
The writing will improve , that is something they don’t have the dexterity to easily do at that age . Push the reading and the math . Mine could read , add , subtract and count her lunch money before she was in kindergarten .
She is grown now
You're a great parent. Not all parents push back at school admins, but they should because of how the school admins underperform their duties. Our 4-year-old here is in pre-school, and it's easy for her because she knows the basics. Our other grandchildren in another state are also in pre-school but with similar skills in reading and writing. We prepped our children while they were toddlers, and they excelled in school and college, succeeding in their jobs, and are now parents of small children.
It's a shame that those Detroit kids are failures, but what the heck were they doing in school those 12 years (or more)? No need to answer, we know why they frittered away opportunity. They were told to take from others, blame others, and depend on others.
