IMO Private testing is invaluable. Especially if ADHD is a concern. We have a very 2e kid who has ADHD (he is very sensory seeking as well), Dyspraxia w/ hypotonia, + some and I would always choose to do private testing whenever you can manage it.
Private testers work for YOU and can get info you need, explain results well that they get, and sometimes advocate specifically for things your child needs to be able to work to her potential at school. Your best/most accurate and therefore most helpful information will come from someone who is experienced with children like yours. Mine would never have finished the WISC without a very experienced tester with extensive experience with 2e children.
One thing you may not know is that if she takes a test like WISC, she cannot be retested for one year with that test. The question usually boils down to "why do you want to test at this time/what do you hope to learn?"...... Your answer to that will hopefully steer you in the best direction for where to test at this time. If it's not the best choice, in a year or two you can try again with a different approach.
Hope you have answers and a responsive and helpful result from school soon.
