If the performance appraisal is the conversation, the appraisal letter is the receipt. It's the document an employee can forward to their partner, save in their personnel file, or, occasionally, hand to an attorney. For that reason, the letter needs to say exactly what the organization intends to say, and nothing more. A well-written appraisal letter wraps up the review cycle with clarity. A sloppy one creates confusion about bonuses, titles, and expectations that HR will be cleaning up for months.
What Goes Into a Standard Appraisal Letter A typical appraisal letter includes the employee's name and title, the review period, the overall rating, a summary of strengths and areas for development, and any resulting actions (salary change, bonus, promotion, or development plan). Some companies add specific goals for the next period. Others keep the letter focused on the review period just closed and handle forward-looking goals in a separate document.
The compensation section is often the part employees read first. If the appraisal triggers a raise or bonus, the letter should state the new salary, the effective date, and any changes to variable pay or equity. Ambiguity here causes real problems when the first paycheck at the new rate doesn't match what the employee thought was promised.
When Appraisal Letters Should Go Out Best practice is to send the letter within a week of the appraisal meeting, while the conversation is still fresh. The letter shouldn't introduce new feedback the employee didn't hear in person. If there's a performance concern, the meeting is where it gets raised; the letter confirms it.
Should the Employee Sign the Appraisal Letter? Many organizations ask employees to sign acknowledging receipt, not agreement. That signature creates a defensible record if the rating is later disputed. Employees who disagree with the rating should be given a clear path to respond in writing, which then gets filed alongside the original letter.
Common Mistakes That Create Legal Risk Vague or contradictory language is the biggest problem. Writing "overall excellent performance" in the summary and then denying a promotion or raise in the same letter invites a legal challenge. Inconsistency across letters for similarly performing employees in protected classes can become evidence of discrimination under Title VII or the ADEA .
Other common errors include promising things the company can't deliver ("you're on track for director next year"), including subjective personal comments, or using the letter to document issues that were never raised with the employee before.
Writing an Appraisal Letter That Actually Lands Start with the rating and the headline decision (raise, no raise, promotion). Summarize 2-3 specific strengths with concrete examples. Name 1-2 development areas with clear expectations for the next period. If there's a compensation change, state the old and new numbers and the effective date. Keep the tone professional and factual. The letter is not the place for warmth or severity the employee didn't already experience in the meeting.
Have HR review every letter before it goes out. A second set of eyes catches inconsistencies between the rating, the narrative, and the compensation decision. For letters that document performance issues, a brief HR review is cheap insurance against downstream disputes.
