What is the role of testing in fair housing enforcement?

• A. Paired testers compare treatment of otherwise identical applicants to detect discrimination.
• B. Inspectors test only to verify building codes.
• C. Owners use tests to measure market rents.
• D. Testers only check for language differences in ads.

Answer: (A)

Testing in fair housing enforcement focuses on revealing discrimination by showing how similarly situated applicants are treated differently. In this approach, paired testers—identical in qualifications and circumstances except for a protected characteristic (such as race, national origin, religion, sex, familial status, disability, or color)—visit housing providers or landlords to compare treatment. By presenting the same rental or purchase scenario, testers can uncover differences in availability, terms, conditions, or services offered, which helps agencies gather evidence of discriminatory practices. This method explicitly aims to detect differential treatment tied to protected status, not to check building codes, measure market rents, or assess language use in ads. If disparities are found, enforcement actions can be pursued based on the documented testing results.
