CLT Study Design
Designing Central Location Tests Around the Research Objective
A successful Central Location Test requires more than placing products in front of consumers. The research design needs to consider the number of products being evaluated, target consumer profile, sample size, product preparation requirements, exposure sequence, evaluation measures and the business decision the study is expected to support.
Census Market Research can execute CLT studies in the UAE using different testing structures according to the project requirements. A study may involve a single product, several formulations, competitive products, multiple consumer segments or a larger number of product cells. The fieldwork structure is then organised around the agreed methodology.
This flexibility is particularly useful for QSR, restaurant, food and beverage research, where research teams may need to compare recipes, flavours, ingredients, preparation methods or competitive alternatives while maintaining consistent testing conditions.
01 / PURE MONADIC
Independent Product Evaluation
Each respondent evaluates one product or product cell, allowing individual products or formulations to be assessed independently.
02 / SEQUENTIAL
Sequential Monadic Testing
Respondents evaluate more than one product in a controlled sequence, with product order managed according to the agreed research design.
03 / COMPARATIVE
Competitive Benchmarking
Products, recipes or prototypes can be evaluated against relevant alternatives to understand comparative consumer performance.
Food, Beverage & QSR Taste Testing
Central Location Testing is particularly suited to products where preparation, serving conditions and immediate sensory experience matter. Food and beverage products can be prepared and presented according to an agreed protocol so consumers experience each test product under more consistent conditions.
CLTs can support the evaluation of burgers, fried chicken, pizza, sandwiches, wraps, fries, sauces, dips, snacks, desserts, coffee, juices, soft drinks and other food or beverage products. Studies can also be designed around new menu concepts, recipe modifications and competitive products.
Consumer Measurement
Measuring the Complete Consumer Product Experience
Overall liking provides an important measure of consumer response, but product-development decisions often require a more detailed understanding of what is driving that response. CLT questionnaires can therefore measure individual product characteristics alongside overall evaluation.
Overall Liking
Taste
Aroma
Texture
Appearance
Aftertaste
Flavour Intensity
Temperature
Portion Perception
Preference
JAR Ratings
Purchase Intent
Just-About-Right (JAR) Measurement
JAR measures can help identify whether a particular product characteristic is perceived as too weak, too strong or at approximately the right level. Depending on the product, this can include sweetness, saltiness, flavour strength, spiciness, crispness, thickness or other relevant attributes. These measures can provide useful diagnostic information alongside overall liking and preference.
Targeted Recruitment
Recruiting the Right Consumers for CLT Research
Product evaluation is most useful when participants reflect the audience relevant to the business question. Census Market Research can recruit consumers against detailed screening and quota requirements for CLT studies in the UAE.
Recruitment criteria can include category usage, current brand usage, competitor usage, consumption frequency, restaurant visitation or ordering behaviour, purchase responsibility, age, gender, nationality and other project-specific characteristics.
Category Users
Consumers who regularly purchase or consume the relevant category.
Brand Users
Current users of specific brands where brand experience is part of the screener.
Competitor Users
Consumers using relevant competing products, restaurants or categories.
Usage Frequency
Heavy, medium, light, regular or occasional users according to the study definition.
Controlled Product Preparation and Serving
Consistency is particularly important when conducting food and beverage product testing. Differences in preparation, portion size, temperature, serving time or presentation can influence how consumers evaluate a product. The fieldwork protocol can therefore specify the conditions required for each test.
Depending on the project, this can include preparation instructions, serving quantities, product codes, serving temperature, presentation sequence, rotation procedures and waiting periods between product evaluations.
Blind & Branded Product Testing
Where the objective is to evaluate product performance with reduced influence from brand cues, products can be presented using neutral identifiers. Branded testing can also be used when the relationship between brand expectations and the actual product experience forms part of the research question.

Multi-Cell CLT Studies
Product-development programmes frequently involve more than two alternatives. A CLT can be organised into multiple cells to accommodate several recipes, formulations, prototypes, flavours or consumer segments while maintaining the sample structure required for each evaluation.
This approach can support QSR menu development, recipe optimisation, competitive benchmarking and other studies where research teams need comparable consumer feedback across several product alternatives.

CLT FAQs
Frequently Asked Questions About CLT Research in the UAE
What is a Central Location Test (CLT)?
A Central Location Test (CLT) is a consumer research method in which recruited participants evaluate products, concepts or other stimuli at a controlled location. The research team can manage product preparation, serving conditions, exposure order and questionnaire administration to create more consistent testing conditions.
What products can be tested through a CLT?
CLTs can be used for food, beverages, QSR menu items, snacks, sauces, desserts and other consumer products suitable for central-location evaluation. Depending on the research objective, the study can test existing products, new formulations, prototypes, recipes, flavours or competitive alternatives.
Can CLTs be used for food and beverage taste testing in the UAE?
Yes. Food and beverage taste testing is an important application of CLT research. Consumers can evaluate attributes such as overall liking, taste, aroma, texture, appearance, flavour intensity, aftertaste, preference and purchase intent under controlled testing conditions.
Can you recruit consumers based on specific QSR or restaurant brand usage?
Yes. Respondents can be screened according to category usage, restaurant or brand usage, purchase frequency, ordering behaviour and other agreed eligibility criteria. Studies can also recruit competitor users or different usage-frequency groups where required by the research design.
What is pure monadic testing in a CLT?
In a pure monadic design, each respondent evaluates one product or product cell. Separate respondent groups can therefore evaluate different formulations or products independently, helping reduce the influence that exposure to another test product could have on the evaluation.
What is sequential monadic product testing?
In sequential monadic testing, the same respondent evaluates more than one product in a controlled sequence. Product order can be rotated or randomised according to the study design to support structured comparison while helping manage potential order effects.
Can competing products be tested in the same CLT?
Yes. CLTs can support competitive product benchmarking. Depending on the research design, consumers can evaluate different recipes, formulations, prototypes or competitor products through blind, branded, monadic, sequential monadic or comparative testing approaches.
What is blind product testing?
Blind product testing conceals relevant brand identity so that consumers can evaluate the product experience with reduced influence from normal brand cues. Neutral product codes can be used where appropriate to the agreed research design.
What can be measured during a QSR or food CLT?
Depending on the product and study objective, measures can include overall liking, taste, aroma, texture, appearance, temperature perception, portion perception, flavour intensity, aftertaste, preference, Just-About-Right ratings and purchase intent.
Can a CLT be used to test a new restaurant menu item before launch?
Yes. CLT research can provide structured consumer feedback on proposed menu items, recipe changes, flavour variants and product formulations before wider commercial decisions are made. The research can help identify consumer preferences and potential areas for product optimisation.
What is the difference between a CLT and a Home Use Test (HUT)?
A CLT evaluates products at a managed central location, providing greater control over product preparation, exposure and testing conditions. A Home Use Test allows consumers to use or experience products in their normal environment over a defined period. The appropriate methodology depends on the product and research objective.
Does Census Market Research conduct CLT research in Dubai and across the UAE?
Yes. Census Market Research supports Central Location Test projects in the UAE, including targeted consumer recruitment, screening, fieldwork coordination, controlled product evaluation and structured data collection according to the requirements of each study.
