The New Mexico Human Rights Act prohibits employment practices that discriminate on the basis of race, age, religion, color, national origin, ancestry, sex, mental or physical handicap, serious medical condition, but it does not specifically address the issue of physical examinations. However, employers may violate the Act if exam policies screen out a particular group or otherwise discriminate on the basis of one of these protected characteristics. The Act covers private employers with four or more employees (NM Stat. Sec. 28-1-1 et seq.). Employers with 15 or more employees are prohibited from discrimination based on sexual orientation or gender identity.
