Who Should the LOR Be Addressed To and Why is it Important?

The LOR for MS in USA is written directly for the admissions committee of your target university.

• Include soft skills: Backup comments on teamwork, leadership, or communication with concrete examples. For instance, “As the project lead, Anjali organized team meetings and ensured smooth communication among members.”

After the body paragraphs, the conclusion solidifies the recommendation and reaffirms the applicant’s potential.

Conclusion Paragraph of the LOR (Word Count: 70–100 words)

The conclusion of your LOR should reaffirm the recommender’s confidence in the applicant’s ability to succeed in the MS program. It should summarize the key messages of the letter and end with a strong, unequivocal recommendation.
