The Power Of Hall Tests
A Hall Test, or Central Location Test (CLT), is a useful market research methodology adopted by Vision One when we are looking to test reactions to concepts and products in a controlled and neutral environment.
They typically involve hiring a venue such as a hotel, hall, office, or pub in a central and easily accessible location which is specially selected for the research requirements or convenient for target participants.
One of the key benefits of the Hall Test market research methodology is presenting respondents with stimuli – food and drink products or advertising examples, for instance. Hall Tests are often used for new product testing such as tasting new food and drink varieties, testing new packaging designs or giving feedback on concepts like branding examples, new product ideas, marketing communications or other product literature. Respondents can then respond to these stimuli live, with the item in front of them, allowing much more opportunity to engage with the product alongside the researcher and brand to understand insights.
Client Feedback
Advertising Testing (CLT)
Central Location Tests are also ideal for testing radio, television or even social media advertisements using Vision One’s AdProbe.
CLTs ensure respondents can clearly see and focus on the execution, allowing them to give a fully informed reaction without the distractions of the home. During the interview, the respondent would be shown the test video (often shown in an advertising reel) and asked questions in order to understand their reactions to it.
Eye-tracking and Facial Expression analysis can be included in adding further System 1 emotional (non-verbal) reactions to the advertising.

Hall Tests Explained
Hall Test respondents are typically recruited on the day of the hall test, often on the street whilst passing the venue.
However, they can also be recruited in advance if the target audience is challenging. On-street recruitment is often the most cost-effective option for mainstream products. It can generate a large number of respondents per day depending upon location, target audience and the length and complexity of the subject area.
Vision One has extensive experience in completing hall and central location tests for a wide range of clients. Test venues are booked within town and city centre locations – recruiters invite passers-by via a short screening interview to participate in a hall test (assuming they meet the target profile).
Nowadays, interviews are most frequently conducted using CAPI (Computer Aided Personal Interviewing) rather than pen and paper questionnaires to ensure fast turnaround and greater accuracy. Interviews typically last 10 minutes or longer, depending on the subject matter and the number of respondent tasks.
