So, you’ve wrapped up something important—a course, an internship, a freelance gig, or even a big construction project. First of all, congratulations! That’s no small feat.
Now comes the often-overlooked but essential part: getting formal proof of what you just accomplished. And for that, you’ll need a Request Letter for a Completion Certificate.
Whether you’re applying to new jobs, enrolling in higher studies, or just building your portfolio, a completion certificate adds that extra layer of credibility. This blog will walk you through how to write a great request letter—plus we’ll include three real examples you can adapt for your own use.
What Is a Completion Certificate?
A Completion Certificate is an official document issued by an institution, organization, or client confirming that you’ve completed a specific task, program, or project.
You might receive one after:
-
Finishing an internship or apprenticeship
-
Completing an academic course or training
-
Closing out a construction or freelance project
-
Participating in research or a volunteering assignment
This certificate becomes a key part of your professional documentation—often requested by employers, universities, or clients.
Why You Need One
Let’s be honest—people trust documents. A completion certificate can help you:
-
Prove you did the work
-
Strengthen your resume or LinkedIn profile
-
Fulfill job or visa requirements
-
Keep official records for future opportunities
Even if you never need it right away, you’ll be glad to have it when that dream opportunity knocks.
When Should You Request a Completion Certificate?
Ideally, send your request within a week or two after finishing the program or project. It shows professionalism and avoids last-minute scrambling when you need it later.
Some typical situations include:
-
After completing an online certification course
-
At the end of an internship or training period
-
Upon final delivery of a freelance or construction assignment
-
After concluding a mentorship or coaching program
How to Write a Request Letter for Completion Certificate (Step-by-Step)
Here’s a simple breakdown of what to include:
1. Start with a Proper Format
Structure your letter professionally:

Your name and contact information
-
Date
-
Recipient’s name, designation, and organization
-
Subject line
-
Greeting (e.g., “Dear Sir/Madam”)
-
Body paragraphs
-
Closing with your name and signature
2. Get to the Point Quickly
In the first paragraph, mention what you completed and clearly request the certificate.
Example:
“I have successfully completed my internship with your organization from January to March 2025. I kindly request you to issue a Completion Certificate for the same.”
3. Include All Relevant Details
Don’t make the recipient hunt for information. Include:
-
Your full name
-
Program or project title
-
Duration (start and end dates)
-
Any registration ID or reference number, if applicable
4. Keep It Polite and Professional
Even if you know the recipient personally, maintain a respectful tone. It makes your request feel thoughtful and sincere.
