Here is how this choice differs from a more limited scale, such as a 4-point scale.
Avoid positive bias in ratings
4-point scales often lead to more polarized responses. Choices become almost binary and limit response variability.
In this context, some employees may hesitate to give a rating perceived as too negative. Responses then tend to cluster around higher options.
With a 1 to 7 scale:
Respondents can express their level of agreement with more nuance
Responses are distributed across more options, better reflecting the intensity of satisfaction
Different perceptions are less likely to be grouped into a single answer
The overall sentiment of respondents is more accurately reflected
Improve result accuracy
A more detailed scale helps better distinguish differences between the various themes being evaluated.
With a 4-point scale, results can quickly look similar from one question to another, making it harder to identify strengths and priorities.
With a 1 to 7 scale, results are more representative and make it easier to identify areas for improvement.
Ensure better tracking over time
A broader scale makes it possible to capture even subtle variations between two surveys.
For example, if several employees move from a rating of 6 to 5 out of 7, this indicates a slight decrease in satisfaction.
This type of variation is difficult to detect with a 4-point scale, where the response might remain the same.
With a 1 to 7 scale, it becomes possible to:
Track progress and declines with greater precision
Detect trends that would otherwise go unnoticed
Better guide actions over time
