CATs are scored as they are administered by Assessment Center.  A theta estimate is calculated after each response.  Short forms and Profiles are scored by Assessment Center after the instrument has been completed. Scoring instructions for short forms are also available in the Resources link in the upper right corner of Assessment Center.  A scoring program, PROMIScore, is also available for download at http://www.nihpromis.org/PROMIScore/Forms/PROMIScore%200%209%204.aspx.  An Excel file of one or many participants’ responses to PROMIS short forms can be uploaded and scored.  It includes graphing functions and is able to handle missing data.
