I'm with others - I've never heard of testing being spread out like that. Typically a neuropsych will take 1-4 sessions, an OT one session and an SLP one session. Scoring and writing the report would be additional time, and then giving the parents a read out is usually a one hour meeting.

The cost in the Boston area for a neuropsychological evaluation runs from $2500 to $3500 depending upon the evaluator.

I sounds to me like there is some therapy going on during the visit and perhaps the evaluator will use this time for observation that could be included in the report?
