I was also pretty strong willed with tests it was hard to test where I was developmentally so they had to go by what my mother said about me than what they were seeing. I wouldn't wear headphones so my hearing couldn't get tested, I wouldn't do other tests so it was hard to see what my abilities were. Then when I was six, my new teacher thought I didn't know my ABCs and other things because I wouldn't do it for her so my mom had to have me do the work at home and bring them to my school and show my teacher. After that she just let my mother write my IEPs for her.
Then when I was eight, I was finally cooperating and doing the tests and I knew it was so I could get into my new school and my mom told me if I didn't do any of those things, they would keep me in my self contained class and I wouldn't go to my new school where all the kids from my neighborhood go. That got me to cooperate.
