Internship Completion Certificate Request

When and how to use this letter

Request the certificate in your final week or within a week of finishing. Memories fade fast, and supervisors change roles; a request made months later is easy to ignore or deprioritize. Asking promptly also lets you correct any errors while the details are fresh.

Email your direct supervisor rather than general HR, because supervisors write the performance remarks that make certificates valuable. Thank them genuinely for the mentorship, since people write warmer certificates for interns they remember fondly. Mention your completion date and role so the certificate can be prepared without back-and-forth.

Specify what the certificate should mention if the company allows input: your role, duration, and one or two key responsibilities or skills. Generic certificates that only state dates carry little weight with employers. A certificate describing actual work, such as managing social media campaigns or assisting with client reports, strengthens your resume considerably.

A practical tip: ask for both a printed copy on company letterhead and a scanned PDF. The PDF is what you will actually attach to job applications, and getting it now saves you from chasing it years later. If the company also offers a recommendation letter, request it in the same conversation while your performance is still vivid in your supervisor's mind.
