# CES Score

[Customer Effort Score](/form-management/form-designer/questions/question-types/satisfaction-questions/ces-score/understanding-ces.md) is a standardized customer experience survey metric that enables you to measure a customer interaction and resolution during a request.

Knowing the CES will help you to better understand the current customer experience and improve it if needed.

CES question assigns a [rating ](/form-management/form-designer/questions/rating.md)to each of its answers from 1 to 7, 1 being highest level of disagreement with the statement and 7 being the highest agreement.

This is a fixed question and its answers can't be modified but you can modify their text through the survey [local resources](/form-management/form-designer/multi-language-forms/local-resources.md) page.
{% endhint %}

The question will also adapt to smaller screens like mobile devices and fall back to an vertical format if the respondent screen's width is too small.
