What Should a Reference Letter Include?

A reference letter serves as a formal endorsement of an applicant’s character, skills, and experience. It provides a third-party perspective that helps a potential employer or academic institution assess a candidate’s suitability beyond their resume. A well-crafted letter can offer a hiring manager deeper insight into an individual’s past performance and future potential, making it a significant component of many application processes.

Gathering Necessary Information

Before writing, collect specific documents from the person requesting the reference. Ask for their current resume or CV, the job description, and any key points or skills they would like you to emphasize. This could include specific projects they are proud of or strengths they believe make them a good fit for the position. Having this information helps you tailor the letter to highlight the most relevant attributes and align your endorsement with the applicant’s goals.

Standard Reference Letter Format

A professional reference letter follows a clear structure to be easily understood. Following a standard business letter format lends credibility to the document. This structured approach helps present your recommendation in a logical and persuasive manner.

Contact Information and Date

At the top of the page, include your full name, professional title, company, and complete address. Below this, provide your email address, phone number, and the date you are writing the letter.

Salutation

The salutation should be formal and addressed to a specific person whenever possible, such as “Dear Ms. Johnson.” If you do not have a specific contact name, a greeting like “To Whom It May Concern” is acceptable.

Introduction Paragraph

The first paragraph should state your identity and your relationship to the candidate. Mention your professional title, how you know the applicant (e.g., as a direct supervisor), and the duration of your relationship.

Body Paragraphs

The body of the letter, consisting of one to three paragraphs, provides the substantive details of your recommendation. This section discusses the candidate’s skills, qualifications, and specific accomplishments.

Concluding Paragraph

In the final paragraph, summarize your endorsement and reaffirm your support for the applicant. Make a strong, positive closing statement, such as “I recommend [Candidate’s Name] without reservation.” You should also offer to provide further information and include your contact details for convenience.

Closing and Signature

Conclude with a professional closing like “Sincerely,” or “Respectfully.” Leave space for your physical signature, followed by your typed full name and title.

Key Content to Include

Impactful reference letters move beyond general praise and provide specific, evidence-based examples of a candidate’s abilities. For example, if the role requires strong project management skills, describe a time you witnessed the candidate successfully lead a team from project conception to completion.

Quantifiable achievements are powerful because they offer concrete proof of a candidate’s contributions. Instead of stating that an employee is good at sales, specify that they “increased their sales territory revenue by 15% over two quarters.” This data provides a clear and measurable indicator of their performance.

Sharing a brief, positive anecdote can also be effective in illustrating a candidate’s character or work ethic. You might describe an instance where the individual went above and beyond their required duties to help a colleague meet a deadline. This story can provide insight into their soft skills, such as teamwork and dedication.

The content should paint a clear picture of not just what the candidate has done, but how they have done it. For example, if the job requires innovation, mention a specific time the candidate proposed a creative solution to a persistent problem, explaining the positive outcome of their initiative.

What to Avoid in a Reference Letter

Avoid using vague or lukewarm phrases like “satisfactory employee” or “did a fine job.” This type of faint praise can be interpreted as a lack of genuine enthusiasm and may do more harm than good, as a reference should be a strong endorsement.

Never include negative information, criticism, or falsehoods. If you do not feel you can honestly provide a positive recommendation, it is better to politely decline the request to write the letter. Embellishing or fabricating details is a serious misstep that can be exposed during background checks, damaging both your credibility and the candidate’s.

Omit personal information that could lead to discrimination, such as a candidate’s age, religion, marital status, or other protected characteristics. Stick to details strictly related to their professional qualifications and performance. Including irrelevant personal details is unprofessional.

Tips for Writing an Effective Letter

Maintain a positive and professional tone throughout the letter. Your language should reflect confidence in the candidate’s abilities and potential. A professional tone helps establish your credibility as a recommender.

For readability and impact, the letter should be concise and ideally no longer than a single page. Hiring managers are short on time, so a clear and direct letter is more likely to be read in its entirety.

Before sending the letter, proofread it for any spelling or grammatical errors. A polished, error-free document demonstrates your own professionalism and attention to detail. Submitting the letter by the requested deadline is also a reflection of your reliability.
