I moved in early jr year of his, to the DC area. It distinctly affected my college choices, as the new hs was a giant step better than the former, the peer competition was almost universally stronger than before, and classroom expectations high. I had some serious catching up to do.
I have zero regrets. What I gained form the move itself and the new intellectual experience was life changing. But the adjustment did point me at a different set of colleges than I would have earned in my other location. A number of opportunities were closed to me as a new kid.
So imo, OP needs to consider how this timing might affect what her girl wants, what she may truly be able to continue to achieve- or not- and how that affects college. What if, for some reason, her robotics options (or role) are limited or the newspaper responsibilities are all sewn up? Is she resilient enough to make the best of this, forge new paths- and maybe see her college possibilities change?
If she doesn’t get into one of the ‘better’ TX college options, can you afford to send her private? What if she doesn’t like those TX colleges and would have been happy at the multiple US or CSU choices?
Can you wait and do this move at a later point in your family life?
