How to Write a Certification Letter (+Tips)

Have you recently been asked to write a certification letter on someone's behalf? Writing a letter of certification can be daunting, and you may not even understand what a certification letter is — much less how to write one. This guide will help you through the entire process, step-by-step.

What Is a Certification Letter?

A certification letter — also very frequently referred to as a letter of certification — is an official letter that serves the purpose of verifying information. A letter of certification is usually written by a person of authority in an official capacity in order to assist an applicant of some kind in completing the required steps.

Anyone may be asked to provide a letter of certification, and that includes people who do not often write such letters. The official nature of this request can easily make you feel intimidated, but you will typically simply need to state the facts.

Types & Uses of a Certification Letter

Why are certification letters used? While the reasons for needing a letter of certification can vary, and therewith also the reasons for writing such a letter, the most common types and uses are:

What Do You Write on a Certification Letter?

The information presented in a certification letter depends on the nature of the request. In some cases, official forms may need to be completed in lieu of writing a certification letter. Where this is not the case, however, and you are called on to compose a letter, it should follow the standard US business letter format (in the following order):

Although the contents of the letter of certification will depend on your purpose for writing as well as the capacity in which you are writing, your letter should always explain:

When an applicant of any type asks you to participate in the process by providing a letter of certification, the requesting party may provide a form or announcement in which they specify details of the information they require. This should help you understand precisely what kind of information is being requested.

If you were not previously informed about the request, you can check in with the party on whose behalf the information is being requested, and ask for their permission to forge ahead with the letter of certification. The party in question will then understand that you are going to write a certification letter in accordance with, to the best of your knowledge, the exact truth.

How to Write a Certification Letter (Writing Tips)

Some people will be used to writing and providing certification letters on a regular basis. These include employees working within administrative departments of colleges and large employers who often need to provide formal references. Not everyone who is asked to write a certification letter falls into this category, however.

You may be a small employer who is encountering a request for a certification letter for the first time, an everyday citizen being asked to write a certification letter for a friend seeking a visa, or a Pastor who was asked to offer a character reference on behalf of an inmate.

In this case, you may have no idea how to move forward. Here are some useful tips that will help you write a professional and credible certification letter:

It is crucial to use formal and polite language throughout any letter of certification. You are advised to remain factual and business-like throughout the letter you write but, where relevant, you may include supporting details that support the applicant's cause (or indeed, depending on the context, dismiss it).

It is equally important to be truthful. Letters of certification are official in nature, and you should never use them as a vehicle to present false information.
