Previous version of ASA24™ (Beta; no longer available)

ASA24-Beta was released in 2009 and supported through the end of June 2012. The Beta Respondent and Researcher Web sites are no longer available.

For access to resources specific to the Beta version (e.g., Beta Respondent Web site Overview, Researcher Instructions, Data Dictionaries, Known Issues), please contact the ASA24 Help Desk.

As a result of updates to the underlying databases, data collected using the Beta version and ASA24-2011 or ASA24-Kids-2012 are not directly comparable (see a table comparing the features of ASA24-Beta, ASA24-2011 and ASA24-Kids-2012). Guidance and code are available to update analytic files from the Beta version, which used FNDDS 1.0 and MPED 1.0, to be consistent with ASA24-2011 and ASA24-Kids-2012, which use FNDDS 4.1 and an updated MPED database. It is not possible to rerun Beta site respondent data using an updated version of ASA24.

If you had an existing study using the Beta version and are interested in using ASA24-2011 or ASA24-Kids-2012, please register a new study.
