Each company should opt for a performance rating scale that works best for them. An effective performance appraisal scoring system should be capable of providing you the right kind of data which can help in improving the productivity of the company and the employee.

Levels of performance must be depicted with transparency

Be prepared to train your employees on the chosen method of performance appraisal rating and how they should interpret each option. Everyone in the organization should be made aware of the performance rating scale and must know how the organization measures success.

Rating scale examples 

There are several performance rating scale examples that can be chosen based on your requirement. For more detailed coverage, choose a scale with more options such as 7 point or 10 point performance scale. Let us look into different rating scale examples based on their complexity and effectiveness,

The 5 point rating scale

The 5 point rating scales are one of the most widely used performance rating scales in the world. The method to rate an employee is fairly simple. The reviewer has to rate each employee out of 5 with 3 being the midpoint. Anything beyond 3 is considered that the employee is exceeding expectations. A rating of 2 signifies improvement needed.

The reviewer will observe employees over a given duration and look into their work ethics. Based on which the final rating is generated. The work ethics include quality of work, discipline, punctuality, team player, workplace enthusiasm, etc. Every workplace has its own unique set of evaluation criteria based on which employees are rated.

The 5 point evaluation scale however is not always effective as each reviewer has their own understanding of what each rating number means. Some raters might give a higher rating for average quality work.

Likert performance review rating scale

Likert scale is another common example of the performance rating system. It also uses 5 options just like the “five-point rating scale” but the options are written out rather than numeric. Here are the five options presented in the Likert employee rating system,

  1. Strongly Disagree
  2. Disagree
  3. Neither Agree or Disagree
  4. Agree
  5. Strongly Agree

A well-designed Likert scale is supposed to have an equal number of negative and positive options with one neutral option. Few systems can also have as minimum as just three options or even seven options to make it more elaborate.

There are a few downsides to this method which makes doesn’t make it completely effective. The presence of a neutral option is an easy way out for the raters who are slacking at their job. The rating system doesn’t provide a straightforward method to score employees unless 5 point rating scale method is fused.

The three-point rating scale

A three-point rating scale is a common form of performance rating scale used by several companies due to its simplicity. It includes standard three points,

  1. Below Expectation – Anyone who fails to meet the desired standards is put into this category. These employees need coaching and training to help them reach the expectation level.
  2. Meeting Expectation – Anyone who is meeting expectations performance review and is consistent with their work falls under this category.
  3. Exceeding Expectation –  Employees who are achievers and have worked beyond the average expectations. Those who bring new standards of working are rewarded under this category. They influence others to perform better.

In a three-point rating scale, the performance evaluation ratings are straightforward without any discrepancy. A large percentage of employees fall under the “meeting expectation” category. The cons of this kind of performance management rating system are that they give birth to centrality bias amongst managers.

The 10 point performance rating scale

The 10 point performance rating scale method is almost similar to the 5 point performance rating scale method. However, it has more options and is not as commonly used in the offices. The performance evaluation rating scale 1- 10 provides more set of options to choose from as compared to the Likert scale and 5 point performance evaluation scale.

The more elaborative 10 point system of rating employees gives a much clearer picture of the employee’s performance. With the 5 point scale rating it is difficult to rate someone who is better than a 3 but not as good as a 4. Whereas, the 10 point performance review ratings have more options to choose from.

The downside of such a system is that sometimes it can get complicated due to the presence of more numbers. It gets more time-consuming for the rater to evaluate an employee.

The 4 point performance rating scale

The 4 point performance rating scale has been proven to be the best option for few companies. As the name indicates, it has 4 options to choose from which are in the written form. The 4 options of the 4 point employee rating scale are,

  1. Needs Development
  2. Consistently meets expectations
  3. Often exceeds expectations
  4. Sets a new standard

The 4 point evaluation rating scale provides more options for the top performance and fewer options for low-performing employees. This helps in making the ratings more fine-grained and out the underperforming candidates in a single needs improvement scale as you do not need multiple gradations for that.

This evaluation scale removes the centrality bias and forces the raters to make a clear choice. They are no longer provided the option to put indecisive candidates in the average category but rather have to determine the meaningful differences.
