An update in the event that somebody with questions on this sort of situation comes across the thread.
Assessment is still ongoing, it only actually started 3 months ago, and the assessor figures he will be done around the end of summer. It's a pretty ridiculous process so far, feels as though the assessor is just filling in the blanks on a pre written form most of the time. There was even a full day that consisted of approximately 1700 multiple choice / sliding scale questions.
Entire thing feels as though its generally geared towards much younger children (mine are 12 & 14), questions involving changing of diapers, actions taken when the child is crying, etc. Observation sessions have included the board game 'Trouble' as well as lego and drawing pictures.
What's astounding to me is that there is no questions for, or on, or interest in my step-daughter that my kids have lived with every other week for the past 9 years.
