    CASES is a software package for collecting survey data based on structured questionnaires, using telephone or face-to-face interviewing,


    , as well as self-administered procedures.  It was developed, distributed and supported by the Computer-assisted Survey Methods (CSM) Program at the University of California, Berkeley until the end of 2014. Beginning in 2015, CSM is managed and supported by the Institute for Scientific Analysis, a private non-profit organization, under an exclusive license agreement with the University of California.

    CSM is a not-for-profit program that is dedicated to enhancing the use of information technology within survey-related organizations in the academic, governmental, and private sectors. CSM also produces SDA, a software package for the documentation and Web-based analysis of survey data.

    For over 30 years, CASES has been one of the most frequently used systems in the United States and has been used in several countries around the World. CASES is backed by a dedicated team of specialists whose continuing activities are primarily supported by the Association for Computer-assisted Surveys (ACS), an international consortium of survey-related organizations.
