Psychologists - As introduced, requires that test materials and test data from psychological or neuropsychological testing be kept secure to avoid compromising the validity of the testing; makes other changes related to security of psychological or neuropsychological test materials and test data. - Amends TCA Title 63, Chapter 11.

HB 677 requires psychologists and neuropsychologists to securely protect test materials and data from psychological evaluations to maintain test validity. It directly affects patients undergoing evaluations, psychologists, and mental health professionals by restricting access to test materials - only licensed psychologists or trained experts can view them, not patients or third parties. Key provisions ban third-party observers (like family or attorneys) during testing, prohibit audio/video recordings, and allow exceptions only for documented disabilities, language needs, minors with psychologist approval, or trainee supervision. The bill aims to prevent compromised test results that could impact high-stakes decisions like custody cases, medical treatments, or forensic evaluations.
