Merit-based principles are standards that prioritize individual qualifications, skills, and performance when making decisions regarding hiring, promotions, and educational opportunities. These principles emphasize fairness and equality by ensuring that opportunities are awarded based on ability and achievement rather than on personal characteristics or demographic factors. The application of merit-based principles is often contrasted with affirmative action policies, which aim to address historical inequalities by considering race, gender, or other identity factors in decision-making processes.
