Cover letter.
A cover letter accompanies your application and resume to tell employers why you are seeking a position.
A resume is wrong because it is not a letter- it is a formally structured document showing your work experience, education, and skills.
Transcripts are documents from your school showing classes, grades, and what degree or program was taken.
Recommendations are letters from other people about you, saying why you are a good employee or what unique skills you have.
