The power of Central Location Testing

A Hall Test, or Central Location Test (CLT), is a useful market research methodology used by Vision One to test reactions to concepts and products in a controlled, neutral environment.

They typically involve hiring a venue, such as a hotel, hall, office, or pub, in a central, easily accessible location that is specifically selected for the research requirements or convenient for target participants.

One of the key benefits of the central location testing research methodology is the ability to present 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 gathering 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 for much more opportunity to engage with the product alongside the researcher and brand to understand insights.

Hall testing explained

What are hall tests?

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 on 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, central location testing interviews are most frequently conducted using CAPI (Computer-Assisted Personal Interviewing) rather than pen-and-paper questionnaires to ensure a fast turnaround and greater accuracy. Interviews typically last 10 minutes or longer, depending on the subject matter and the number of respondent tasks.

A Central Location Test (CLT) is a form of in-person market research where participants are invited to a specific venue to evaluate products, concepts, or experiences. Respondents complete a structured survey after interacting with the product in a controlled environment.

Vision One offer a wide range of alternative quantitative research methodologies

CLTs and hall tests are particularly useful when participants need to physically experience something, such as tasting food and drink, testing consumer products, evaluating packaging, or comparing multiple concepts side-by-side.

Hight Street locations with a good footfall outside are often used to recruit people on the spur of the moment.

For niche or low footfall areas, participants may be recruited in advance through research panels or customer databases, or approached directly at the venue. Screening questions are used to ensure they match the target audience for the study.

Most Central Location Testing last between 15 and 30 minutes, depending on the number of products or concepts being evaluated.

CLTs are often used for food and beverage testing, personal care products, packaging evaluation, new product concepts, advertising materials, and sensory testing where touch, taste, or smell are important.

However, they can also be developed for cars and other vehicles (Car Clinics). They can also be set up for advanced neuromarketing research – such as eye-tracking, IRT testing etc.
