In short

An internship certificate is a signed letter, on company letterhead, confirming that a student completed an internship. It states the intern’s name, college and course, the role, actual start and end dates, and the work done. It carries a certificate number, the date of issue, the signatory’s name and a contact for verification. Issue it promptly after the internship ends, once the dates and work are verified.

These templates are a starting point, not legal advice. Check the final wording against your company policy and with your HR or legal adviser before you send it.

What to include

Letterhead, a unique certificate number and the issue date.
The intern’s full name as it appears on college records, with course, college and, if the college asks, the enrolment or roll number.
The role and team, as recorded in your internship records.
Actual start and end dates, with the working pattern (full-time or part-time) and the mode (on-site, hybrid or remote).
The work done: a project title, or two or three tasks, described in a sentence or two.
Skills or tools used, when the mentor can name them.
A performance or conduct note on a scale you have defined, only when it is true and has been asked for.
Name, designation and signature of an authorised signatory, with a seal if you use one.
A verification contact: an HR email or phone number, and a line asking the reader to quote the certificate number.

How to issue it

Collect the facts from three records: the offer letter, the attendance or timesheet, and the mentor’s feedback. Note any change from the planned dates, and take the intern’s name from their college ID.
Ask the mentor for two lines on the work, two or three skills and, if you give a performance note, a rating from your scale.
Ask the intern what the college needs. If it has its own form, logbook or seal requirement, complete that too, and leave your own certificate with the intern.
Fill in the matching version and give it the next number from your certificate register. If the intern came through an internship you posted on LineupX, check the role title against that posting and the offer, and use the title the intern actually held.
Have the authorised signatory sign, then email the signed PDF from an official company address. Record the number, name, dates and date sent in the register.
Check the requester’s identity and purpose, and confirm the intern’s authorisation before sharing information. Reply from the printed HR address with only the details needed for the authorised verification.

Mistakes to avoid

Planned dates in the offer may differ from the period actually served; use verified actual dates on the certificate and retain any agreed changes with the internship records.
Praise nobody can check, such as ‘excellent in all areas’, carries no weight; name the project and two skills, and give a rating only if the mentor reviewed the work.
A certificate with no number and no verification contact leaves a college or recruiter unable to confirm it; number every certificate from a register and print an HR email.
Spelling the intern’s name differently from college records can get the certificate rejected; copy it from the college ID card.
Calling an early exit a completion misstates the internship; record the period actually served, or issue a participation letter if your policy allows it.
Handing over an editable Word file lets anyone alter the dates afterwards; give a signed PDF on letterhead.

Verification: make the certificate checkable

Colleges and recruiters do check internship certificates. Build the checking in by giving every certificate a number from a register that records the intern’s name, role, dates and the date you issued it.

Print an HR email address and ask requesters to quote the certificate number. Check the requester and the intern’s authorisation before confirming the relevant details.

If your company already runs an online verification page or adds a QR code to certificates, put that on the certificate. Do not add one just for this.

Writing a performance note that holds up

A performance note is optional. Add one when the college asks for it or the mentor has reviewed the intern’s work. If you grade, use a scale you have written down, with one line on what each level means, and apply it to every intern.

Support the rating with facts: the project, two skills and the attendance. ‘Good attitude’ cannot be checked, but ‘delivered the feedback report on schedule’ can.

Use the rating that matches your documented criteria and the mentor’s evidence. Do not substitute a more favourable label. If you have no defined rating scale, describe the work completed without assigning a grade.

Early exits, short internships and college formats

If an intern leaves before the end date, do not issue a completion certificate. If your policy allows it, issue a letter that states the dates actually worked and the work done, and do not stretch the dates.

For an internship of a few weeks, a half-page certificate is enough. Keep the dates, role, work and verification contact, and drop the skills and rating unless someone asks for them.

Some colleges set their own format, logbook or seal requirement, and some set a minimum duration. Ask the intern what the college needs before you finalise, and complete the college’s form too; your certificate stays with the intern.

Questions about the internship certificate

What is the difference between an internship certificate and an experience letter?

An internship certificate records an internship, including the role, actual dates and work completed. An experience letter records employment. If an intern later joins as an employee, document each arrangement using its actual dates. Check any apparent overlap against the records rather than changing dates simply to make the documents agree.

Who should sign an internship certificate?

The signatory should be someone who can speak for the company and can see the internship records, such as the HR head, a director or the founder. Name the mentor in the text rather than asking the mentor to sign, unless your company lets managers sign. Print the signatory’s name and designation under the signature.

When should the internship certificate be issued?

Issue it promptly after the internship ends and you have verified the actual dates and work completed. Track handover and company-property returns separately. If someone requests it months later, use the verified internship dates and the actual date of issue. If completion is disputed, ask your HR adviser how to record the facts accurately.

Should the certificate mention the stipend?

No. The certificate confirms role, dates and work. Keep the stipend in your offer letter and payment records. If the intern needs proof of stipend for a college or a bank, issue a separate letter, and ask your accounts team what it should say.

Is a performance remark required?

No. Colleges differ: some need only dates and role, while others ask for a remark on conduct and performance. Add one when it is asked for and when it is true. Use a short, defined scale, so that two interns who did equally well get the same words.

Can I issue a certificate for an unpaid or remote internship?

Yes, the certificate works the same way. For an unpaid internship it says nothing about pay, which stays in your offer letter and records. For a remote one, say that the work was done online, and name the tools and deliverables. Print the same verification contact on both.

Can I send the certificate digitally?

Yes. Export the signed PDF on letterhead, email it from an official company address and log it in your register. A digital copy is easy for a college to forward, and the verification contact printed on it lets the reader check it.

What if an intern loses the certificate?

Find the entry in your register by name, role and dates, and issue a copy marked ‘Duplicate’. Keep the original certificate number and the original date of issue, and show the date the duplicate was issued separately. Do not change the dates or the wording.
