Once or twice a year many companies undergo a formal performance review process. On average, most companies ask for their employees feedback by way of a self-evaluation. Most employees exude an audible groan, give it a cursory overview and write down the same garbage year after year.

As much as I don’t totally agree with the standard annual review process or the 360 review process on principle, I totally support the notion that an employee is his or her own best advocate. And if you are given the opportunity to speak for yourself, absolutely take it seriously and follow these do’s and don’ts.

Do keep a  running diary or file  ALL YEAR ROUND of all of your work accomplishments, projects completed, client accolades, awards, educational achievements and peer praise. Also, keep notes on areas you made mistakes, encountered the issue again and improved.

Don’t blow off the process by not writing anything or digging up last year’s review and re-writing the same things. This is a signal to your boss that you are not taking the process seriously. Why would your manager bother with putting any effort into your review or development, if you do not bother yourself.

Do provide concrete and clear examples of the competencies you have demonstrated over the course of the review period. For example, if your company prizes efficiency, provide an example of the time you identified a redundant process inside a workflow, brought it to the attention of management, and how the elimination of that process resulted in less time taken to complete the process.

Don’t sell yourself short. Provide any and all examples of your work accomplishments, do not make judgement calls on the level of impact to the business or department. Your role and your performance have a purpose to the company, otherwise the job wouldn’t exist.

Do provide areas that you may have failed in or areas of improvement. You should be the first one to bring this up, not your manager. It shows you have self-awareness and that’s important.

Don’t rate yourself as a “Meets Expectations” or “Average” on all rating categories. This is called Central Tendency Bias and highlights our human propensity for avoiding extreme categories. But this is just lazy, don’t do that.

Do review your performance reviews from prior years so that you can identify areas that you have improved upon over time. If you don’t have copies, ask your manager or HR.

Don’t forget to address your work goals. The review process is about the past but should also provide some direction for the future. Be the first to write down a few goals that you would like to address with your manager during the performance discussion.

Do proof-read your self-evaluation for grammar, spelling and content before you turn it into your manager.
