The 2016 versions of the ASA24 system require high-speed internet and are accessible using desktops, laptops, tablets, and smartphones. The user interface is written in HTML5. Unlike previous versions, the 2016 versions enable the ASA24 system to load on commonly used web browsers without downloading Microsoft Silverlight or other plug-ins.

The 2014 versions of ASA24 will continue to be available for use until March 2017. Please note that the use of the 2014 and prior versions of ASA24 requires high-speed internet access, as well as Microsoft's Silverlight browser plug-inExternal Web Site Policy. Currently, the Silverlight plug-in can be used in Internet Explorer, Firefox, and Safari; however, the plug-in will not run using the Chrome browser. Silverlight will not be supported in the near future by most commonly used web browsers; therefore, all Researchers will be required to switch to ASA24-2016 or ASA24-Canada-2016 by March 2017. There are currently no funds to update ASA24-Kids-2014. Researchers should use ASA24-2016 instead.

For Researchers using earlier versions of the ASA24 system who have switched mid-study to a 2016 version:

  • The underlying nutrient and food group databases for versions prior to ASA24-2016 are not directly comparable (see a table comparing the features of all versions of ASA24). At some point in the future, guidance and SAS code will be made available to update analytic files from older versions to use comparable food and nutrient databases as ASA24-2016. ASA24-Canada-2014 and ASA24-Canada-2016 use the same nutrient databases but the 2014 version, unlike the 2016 version, does not include food groups. It is not possible to rerun ASA24-2011, ASA24-2014, or ASA24-Canada-2014 Respondent data using ASA24-2016 or ASA24-Canada-2016.
