Assessment Center is a free, online research management tool.  It enables researchers to create study-specific websites for capturing participant data securely.  Studies can include measures within the Assessment Center library as well as custom instruments created or entered by the researcher.  PROMIS instruments (short forms, CATs, profiles) are a central feature of the instrument library within Assessment Center.  Any PROMIS measure can be downloaded for administration on paper or be included in an online study.  Detailed statistical information and development history about PROMIS items and instruments is available for review.

Assessment Center enables customization of item or instruments (e.g., format, randomization, skip patterns), real-time scoring of CATs, storage of protected health information in a separate, secure database, automated accrual reports, real-time data export, graphing of individual CAT or Profile scores, and ability to capture endorsement of online consent forms among many other features.
