Research & Testing

Our consumer product and service testing center, in Westchester, New York, is the largest nonprofit educational and consumer product testing center in the world. And our 327-acre auto test center is the world’s largest and most sophisticated independent automobile testing center devoted to consumer interests.



Data is the basis for virtually all the work that Consumer Reports does. To provide scientific analysis to our testing teams, our investigative reporters, and our policy advocates, we have teams and tools to inform us about industry trends and product categories. We’re able to combine CR members’ feedback with search engine trends and technical data from government, academia, and industry to find the connecting threads underneath the numbers. These insights ensure that our tests reflect how consumers actually use a product, that our testimony to a government panel is fact-based and supportable, and that we can plan for the products we’ll need to purchase in the future to do our work.

Buying, Testing, and Rating

We buy and test thousands of products every year to generate reviews and ratings to help consumers, support our investigative journalism and trusted consumer guidance, and advocate for consumer-friendly marketplace practices. Before any product even enters one of the dozens of labs at our Westchester, NY headquarters, CR conducts considerable research — gathering data about products and services, consumer demand in the marketplace, and what our members care about most. Editorial, technical, and research staff then scrutinize that material, along with suggestions from our members, to develop our testing protocols and schedule.

After additional research to define any testing project's scope, staff shoppers or one of our anonymous “secret shoppers” buy the products we use as test samples — in fact, some products, like house paint and food, can vary by climate or region, and because we need to make sure our tests reflect a national consumer experience, we purchase products from across the country. Our shoppers pay full retail and purchase all the products we test to generate our ratings from the same places consumers do; we accept no sample products for testing. And as a nonprofit organization that accepts no advertising, to pay for all this shopping we rely mostly on our millions of members and the hundreds of thousands of donors who support our work. For example, in the coming fiscal year, we expect to spend more than $27 million to test, rate, and review 8,500+ products and services.

We have more than 140 testing and research experts who work in our home, cars, technology, product safety, statistics, survey research, food safety, health ratings and market research teams.

Our experts use only state-of-the-art testing equipment, along with some equipment designed by our engineers — since the actual tests are based not only on government and industry standards but also on standards our specialists develop to recreate the experience you'll have with the product. Sometimes our test methods become part of an industry's standards. And sometimes individual companies will work to improve their own competitive advantage by meeting our testing standards for everyday-use cases in their own quality assurance departments.

Consumer Surveys

Throughout our history, we have worked side-by-side with consumers. The earliest example of such partnership is what’s still called our Annual Questionnaire, or “AQ.” Today, the AQ is a sophisticated, year-round operation of communications and data crunching.

Like the rest of Consumer Reports, the Survey Research department is free of corporate influence and advertising. Our surveys are not commissioned or financed by industry. Rather, these surveys are designed to gather unbiased, objective information from consumers.

To conduct the AQ, our Consumer Reports Survey Research department surveys millions of consumers each year using state-of-the-art techniques, collecting feedback on a broad range of real-world experiences with products and services. Survey topics include model-level reliability for cars, trucks, and SUVs; brand reliability for appliances and electronics; and ratings of services such as cell-phone service providers, hotels, airlines, auto and homeowner insurance, and retailers.

Our annual auto owner satisfaction survey yields information on hundreds of models based on responses from hundreds of thousands of car owners. We also survey consumers on financial services, complex healthcare topics, and treatments for health conditions.

We conduct over 100 surveys each year, seeking information from both CR members and Americans at large. Member surveys are sent to a random sampling of the millions of Consumer Reports members, some of the savviest shoppers in the nation. These surveys afford us very large sample sizes and permit the extensive and detailed analysis required to rate brands and retailers across a large number of products and services. The Survey Research department also conducts nationally representative surveys of thousands of Americans, allowing us to represent accurately the entire U.S. population.

Data Intelligence

The digital marketplace is more complex and connected than ever before. Technology and the rapid pace of innovation are creating new challenges for consumers, different from those they confronted in 1936 when CR was founded. CR is compelled to meet these challenges head-on. We are unleashing the power of consumer-driven insights to fuel change and innovation, and developing new ways to shape the marketplace in favor of consumers.

CR Data Intelligence is a new marketplace change program. The goal: to foster the development of products, standards, and policies that prioritize safety, security, performance, and quality for consumers. We call it “upstream impact”—improving products and services before they get to market.

For over 80 years CR has helped consumers to make better choices. Now we can contribute to making the products themselves better. 

How CR Data Intelligence Works

CR independently tests thousands of products and services in our labs each year and surveys hundreds of thousands of consumers about their experiences with products and services. Personal data from this research is not shared. We decide which products to rate and buy all the products at retail, just as consumers do. We rely on this data to power our unbiased ratings and reviews for consumers.

CR Data Intelligence offers subscriptions to data and insights from CR’s rigorous and trusted research, testing, and surveys to industry experts, including manufacturers, regulators, and researchers. As with all our programs, products, and services, 100 percent of the fees we collect support our nonprofit mission.
