Researchers, clinicians, and teachers can visit the Researcher Website to access the Researcher instructions and register to use U.S. or Canadian versions of the ASA24 system free of charge. Registering requires reviewing and agreeing to the ASA24 User Agreement [PDF - 98 KB].
Researchers do not need to specify the language that will be used by Respondents when registering a study.
If your study includes both adults and children and you wish to use multiple versions of the ASA24 Respondent Websites (e.g., ASA24-2016 and ASA24-Kids-2014), please register a study for each version. ASA24-Kids-2016 and ASA24-Canada-2016 (mobile accessible) are under development.
