I'm a little late on this, but apparently there is a 50 point assessment test designed by Cambridge University to assess where an adult falls on the autism spectrum. Those in the autism community consider this a fairly accurate test. Average adult males score at or around a 17, average adult females score at or around a 15. 35 points or highter is associated with Asperger's Syndrome. I took the quiz and scored a 15, totally average for a female.
