Integrity involves avoiding shortcuts or unethical practices, such as cheating or plagiarism, which can undermine an aspirant's potential. Upholding integrity fosters a deeper understanding of subjects, which is essential for public service. Candidates must be self-disciplined, ensuring their preparation reflects their values, thereby promoting accountability in their future roles as civil servants.
