The Postal Service gives examinations to measure job-related knowledge, skills, and abilities. One use of test scores is to compare the performance of individual competitors to make employment decisions. You must ensure that accommodations do not affect an individual’s score to the extent that it cannot be compared meaningfully to the scores of other competitors. Therefore, the Director, National Human Resources, must approve any proposed accommodations or changes in the testing process that may affect the meaning or interpretation of test scores.
This ensures that the competitive nature of the selection process and the validity of the test are not compromised.
