An internship certificate is an official document an organisation issues to an intern after the internship ends. It confirms the intern’s name, college and course, the department, the start and end dates, the role or project, and a short remark on performance. It is printed on company letterhead, carries a reference number and date, and is signed by an authorised person such as the HR manager or the intern’s supervisor.

This guide lists the details to include, gives a fill-in certificate, seven samples and a request letter interns can send if the certificate is delayed.

Key Takeaways

  • Print it on letterhead with a reference number, date and authorised signature.
  • Give exact dates: “from 1 June 2026 to 31 July 2026”.
  • Name the department, role and main project in one or two lines.
  • Add a short, honest remark on conduct and performance.
  • Colleges often need it for credits, so include the college name and course.

Internship certificate vs internship completion letter

Many companies use both terms for the same document. Some issue a short “completion letter” for the college and a formal certificate for the intern’s records. In contrast, an internship offer letter is issued before the internship begins and states the terms.

Tips for Employers

  • Issue it on time. Students often need the internship certificate within days for college credit.
  • Keep a register. Record reference numbers so that you can verify certificates later.
  • Use one template. A standard format keeps every internship certificate consistent.
  • Add contact details. Colleges and future employers may want to verify the internship.

Mistakes to Avoid

  • No dates or wrong dates. Colleges check duration for credits.
  • Generic remarks only. Mention the actual project or tasks.
  • Unsigned certificate. An authorised signature is essential.
  • Wrong name spelling. Match the college ID or mark sheet.
  • Overstating work. Describe only what the intern actually did.

Related Office Formats

For full-time employees, use our experience letter format. Before an internship, companies send an offer letter, and interns may report with a joining letter. Colleges sometimes ask companies for an application for bonafide certificate before approving an internship.
