Disparate impact and disparate treatment refer to discriminatory employment practices. The distinction between these two types of discriminatory practices often focuses on the employer’s intent.

Disparate impact is often referred to as unintentional discrimination and disparate treatment is often referred to as intentional discrimination. The terms adverse impact and adverse treatment are sometimes used in place of disparate impact and disparate treatment.

Disparate impact occurs when policies, practices, rules, or other processes that appear to be neutral result in a disproportionate impact on a protected group of persons.

For example, testing all applicants and using results from that test that will unintentionally eliminate certain minority applicants disproportionately is disparate impact. And testing a particular skill of only certain minority applicants is disparate treatment.

Federal laws prohibit job discrimination based on race, color, sex, sexual orientation, gender identity or expression, national origin, religion, age, military status, equal pay, pregnancy, disability, or genetic information and prohibit both disparate treatment and disparate impact discrimination.


In Louisiana, as in all states, employment discrimination is governed by both federal and state laws. Disparate impact refers to policies or practices that, while neutral on their face, disproportionately affect a protected class of individuals without the employer intending to discriminate. Disparate treatment, on the other hand, involves intentional discrimination where an employer treats an individual or group differently based on their protected characteristics. Federal laws, such as Title VII of the Civil Rights Act of 1964, the Age Discrimination in Employment Act, the Americans with Disabilities Act, and others, prohibit both disparate impact and disparate treatment based on race, color, sex, sexual orientation, gender identity, national origin, religion, age, military status, and other protected characteristics. Louisiana state law also prohibits employment discrimination and is enforced by the Louisiana Commission on Human Rights. Employers in Louisiana must ensure that their employment practices do not create a disparate impact or involve disparate treatment of protected groups.
