A Central Location Test (CLT) or Hall Test is a face-to-face survey method where respondents are invited, with or without prior notice, to some convenient place (ranging from a public meeting place to a research field facility). This format is used for studies requiring extensive stimulus material to be shown and/or tested in neutral, unbiased conditions. CLT is conducive to finding special target samples, such as ethnic groups, children, and teens. Mall intercepts offer stringent validation procedures, allow clients to directly observe interviewing, provide greater confidentiality than other research methods, and will not be impeded by pending legislation that will narrow the ability to recruit respondents in other survey methodologies.
