Recommendation Letter for Promotion

I work as a supervisor in a certain firm. I want to recommend some three juniors for promotion. Please draft one recommendation letter for me. Attached are details of what they do and their performance appraisal scores we carried out recently. Write a letter of about 250 words, and a separate paper of something like a report that whoever will read the letter will check at the summary of important details. Use the attached information. Thank you!
