TPI offers periodic recertification to any previously Certified PANSS rater. We consider this to be an integral part of the program, allowing each rater to ensure that their skills and calibration with the scale remain adequate over time. When required, TPI will recommend “recalibration” in the form of additional training. TPI helps to ensure that the raters are up to date with the most recent standards, providing ongoing support while they continue to utilize the PANSS to the best of their ability.
