What reasons do applicants use to write résumés, and what reasons do employers use to evaluate them? This article advocates for teaching reasons as a way to empower writers to make more nuanced, adaptive résumé decisions. Drawing from a study of 63 students, 20 advisors, and 24 employers, the article touches on résumé format, sections, and items; then it moves beyond formal features to compare eight reasons that participants used as a framework in their decision making: relevance, recency, value, personality, fluff, unprofessionalism, discrimination, and applicant fit. It ends with pedagogical suggestions for teaching this framework alongside résumé formal features.
