Internship Completion Certificate: mistakes to avoid

  • Never send an editable Word file for anything that carries weight.
  • Read it aloud once. Anything you stumble over, the reader will too.

Frequently asked questions

What is the correct format for a Internship Completion Certificate?

Sender address, date, recipient address, a salutation naming a person where possible, a subject line, the body in short paragraphs, a complimentary close, and a signature block. Block format — everything left-aligned, a blank line between paragraphs — is the safe default.

Should I send it as PDF or Word?

PDF, unless the recipient asked for an editable file. It renders identically everywhere, cannot be altered by accident, and is what HR and legal teams expect to file.

How formal should the tone be?

Match the reader. Resignation, offer and legal letters stay formal and factual. Thank-you and cover letters can be warm, but never casual — no contractions in the opening line.

Is this template free to download?

Yes. Edit it, export to PDF or Word, and send it — no account, no watermark, no limit on how many you create.
