Assessment CenterSM is a online data collection tool that enables researchers to create study-specific websites for capturing participant data securely online.

Studies can include measures within the Assessment Center library as well as custom instruments entered by the researcher. The instrument library includes self- and proxy-report short forms, computerized adaptive tests (CATs), and batteries or profiles from:

  • Patient-Reported Outcomes Measurement Information System (PROMIS)
  • Quality of Life in Neurological Diseases (Neuro-QoL)
  • NIH Toolbox
  • Health LiTT

Among other important features, Assessment Center also enables:

  • Downloading library instruments for administration on paper
  • Customization of items or instruments (e.g., format, randomization, skip patterns)
  • Real-time scoring of CATs and short forms
  • Storage of protected health information (PHI) in a separate, secure database
  • Automated accrual reports
  • Real-time data export
  • Ability to capture endorsement of online consent forms


Assessment Center will be retired effective February 28, 2022. If you are a current user and have not talked with the Assessment Center team, please email us at We will work with you to create a solution that doesn’t disrupt your work.

If you are interested in an administrative platform, there are many choices that include PROMIS, Neuro-QoL, NIH Toolbox, and other patient-reported outcome measures. Learn more about other Administration Platforms on We recommend REDCap for research studies, the Epic PROMIS CAT application for Epic users, and the Assessment Center API for integration into other electronic administration platforms.
