Which of the following is NOT addressed under the Equal Pay Act?

The Equal Pay Act primarily focuses on the principle of equal pay for equal work, specifically prohibiting wage discrimination based on gender. This law requires that men and women receive equal pay for performing similar jobs that require equal skill, effort, and responsibility under similar working conditions.

When examining the options, race-based compensation is not addressed under the Equal Pay Act; instead, it falls under other laws such as the Civil Rights Act, which prohibits discrimination based on race, color, religion, sex, or national origin. The Equal Pay Act's emphasis is specifically on gender-based compensation, thus leaving out race as a category when considering wage discrimination.

On the other hand, gender-based compensation is directly addressed under the Equal Pay Act, as it aims to eliminate wage discrepancies between male and female employees performing equivalent work. Job performance differentials and considerations for credentials and education can also be relevant factors when determining pay under the Equal Pay Act, as long as they do not lead to gender-based disparities that violate the spirit of the law.

Therefore, the correct distinction here is that race-based compensation does not fall under the purview of the Equal Pay Act, making it the appropriate answer.
