What study sample size can be accommodated by ASA24?
ASA24 was designed to manage multiple, large epidemiologic studies simultaneously. Should a researcher wish to use ASA24 for a very large study (i.e., thousands of respondents), it is advisable to arrange the timing of recalls so that not all respondents are attempting to access the system on the same days. See the Researcher Web site instructions (PDF) for more details on the scheduling of recalls. For studies involving 500 or more respondents, please contact us prior to registering on the researcher site so that strategies to accommodate the load on the system can be discussed.
