You want to be sure that the neuropsych is the adult version so taking it closer to college is wise. Also keep track of what the rules might be for keeping accommodations in place for professional exams for grad programs such as LSATs, MCATS, and professional licensure certifications in most professions later on such as teaching, nursing, law, medicine etc. If evidence of a disability is required, then you want to see the length of time an evaluation is accepted.
