Internship Certificate Format

What is an Internship Completion Certificate?

An internship completion certificate is a signed statement from the host organisation. It says that a named person interned there, in a named role, between two dates. Universities count it towards credit, and professional bodies count it as experience. Recruiters read it as the only outside proof that a line on a CV is real. Without one, an internship that ran for six months is, on paper, just something the candidate says happened.

Companies, law firms, hospitals, NGOs, newspapers, research labs and start-ups all issue these. They usually go to a student whose degree makes an internship compulsory. Engineering, management, architecture, law, social work, journalism and clinical courses often require a set number of weeks signed off by the host. Only then does the university release the credit. The intern then uses the same certificate three more times. It goes in a placement file, in an application for a master’s programme and in the experience part of a background check. There, a recruiter may ring the person who signed it to confirm it.

Whether an internship can be unpaid is a separate legal question from whether you certify it. The answer depends on where the work happened. In the UK it turns on whether the intern counts as a worker under National Minimum Wage rules. In the US it turns on how the Fair Labor Standards Act treats interns. Across the EU it depends on national law, which differs by member state. Universities also set their own format. Many supply a set form, often called a proforma, with the supervisor’s job title, the credit hours and a grade. Check whether one exists before you design your own. A letterhead version may be refused where the university issued a proforma.

A completion certificate records attendance and dates. It is not an employment contract. On its own, it does not make the intern an employee or give them a claim to a job. It is not a reference either. A recruiter who wants an opinion on the intern’s work needs a separate letter. Folding praise into it blurs a statement of fact with a judgement, so keep to the short conduct line. It is also not proof of what was paid. If the internship had a stipend, the payslips and any tax deduction records show the earnings, not this.

How to write an Internship Completion Certificate

1. Print it on your letterhead

   A certificate on a blank sheet is worth very little to anyone checking it. Use headed paper with the registered name, address, phone number and website. That is what a recruiter uses to trace you when they check. Include a company registration number if you have one. If you are a small team with no letterhead, a footer with the full legal name and registered address does the same work.

2. Give exact start and end dates

   Write the day, month and year the internship began and ended. Add the total in weeks, or in hours if the college counts hours. ‘Interned from 1 June 2026 to 24 July 2026, eight weeks, full time’ can be checked against a course rule. ‘Interned during summer 2026’ cannot. The course office will then send the student back to you for a corrected copy.

3. Describe the work in specifics

   Write two or three lines naming the department, the supervisor and what the intern actually did. ‘Worked in the accounts team on supplier reconciliation and helped with the monthly close’ is useful to the next employer. ‘Worked across various departments and gained valuable exposure’ is not. That sentence is on so many certificates that few readers look closely.

4. Sign it as a named, reachable person

   The signatory should be someone who can confirm the facts a year later. That means the supervising manager or the HR lead, not a director who never met the intern. Print the name, job title, direct email and phone below the signature. Add a reference number. Keep a simple register of what you issued to whom, so a check call takes two minutes rather than an afternoon.

5. Match the college’s proforma if it has one

   Ask the intern whether their college or university supplied a format. Type the college’s name in the institution box, so the certificate says whose student they are. Many colleges require the supervisor to fill in attendance, project title, hours and sometimes a grade, and to stamp each page. Where a proforma exists, complete it. Then issue your own letterhead version as well. The student needs the proforma for credit and the letterhead copy for job applications.

Common mistakes

• Issuing the certificate on plain paper with no address or phone number, so nobody can check it, and experience that cannot be checked usually counts for nothing.
• Giving only the month and year for the start and end, which fails a course rule on minimum weeks and sends the student back to you at the worst time.
• Filling the description with ‘gained valuable exposure’, which wastes the one line a recruiter reads and leaves the intern with no outside account of what they did.
• Letting the intern draft the certificate and signing it unread, which means you have certified claims you cannot support when somebody rings to check.
• Skipping the issue register, so when the certificate is lost — and it will be — you have no record to issue it again from.
