how admissible are neuropsychological tests in a court of law?

Answer 1

The general standard for expert witness testimony is that the expert is there to assist the trier of fact (usually, the jury) in determining complex issues outside the range of common knowledge.

The expert witness is allowed to base their professional opinion on any materials that are commonly used by similar professionals to reach conclusions. Where there is a question of whether such materials are commonly used, the expert can generally rely upon any materials or procedures that have been subject to objective and extensive peer review by similarly qualified professionals.

It's important to remember that it's the expert opinion that is admitted, in the form of testimony. Reports that are specifically prepared for the trial by the expert cannot generally be admitted separately as documents to prove their contents.

This is how things tend to work under common law jurisdictions, including most US courts. Individual rules vary depending upon the jurisdiction, and the topic. Check your local listings.
