Promotion and tenure (P&T) letters are a key component of academic career advancement. These letters serve as a critical part of the P&T application packet and speak to the candidate's qualifications based on the letter writer's personal experience (i.e., letter of endorsement) or an objective "arm's length" review of the applicant's materials and reputation (i.e., letter of evaluation). It is common for academicians to write multiple P&T letters on behalf of others each year. Writing a letter for promotion takes time, effort, and preparation. While writing letters for promotion offers little recognition, it is an important function for advancement of faculty. This is especially critical for promotion to the rank of professor, because there may be fewer faculty at this rank available to write letters. 1 While many have experience in writing letters of recommendation for students or trainees, the P&T letter has unique characteristics. Many faculty may not have received specific training or garnered sufficient experience in writing P&T letters before being invited to write one, and feedback is rare. There is a need for guidance for faculty who are called upon to engage with the academic community by reviewing and assessing dossiers for P&T purposes.
