Performance standards refer to a set of expectations or criteria that define what is considered an acceptable level of performance in a particular task, role, or job. These standards are used as benchmarks against which actual performance can be measured and evaluated. They provide guidelines for how well someone must perform their duties in order to meet the required levels of proficiency, productivity, efficiency, quality, safety, or other relevant factors. Performance standards may vary depending on the specific job, industry, organization, or location, but they are generally established to ensure consistent and high-quality outcomes.
