an assessment generally has several parts. The tester will ask you about your childhood and your past and look for evidence of autism in the way you speak, move, respond, etc. They will give you tests on paper or ask questions that talk about the way you struggle in the world and also look for your best strengths. Some of the tests I took were on paper, some 'hands on", some just asked by the person giving the evaluation. I even used a computer for part of it. What they are looking for is signs of uneven neurological development, with very strong abilities in a few places and other places where we struggle or have difficulties. I could not finish several parts of testing , one section I was completely lost and never answered a question. That is OK, its not "pass/fail" but the tests are meant to show our strengths and weaknesses. Its OK to tell them if you are worried or anxious, they will understand and try to help you through it! Keep us posted!
