The FLACC Scale is a behavioral scale for scoring postoperative pain in children between the ages of two months and seven years or in persons unable to communicate.

The FLACC Scale was developed to provide a simple framework for assessment, while facilitating a reliable and objective means of quantifying pain behaviors in children. This tool includes five categories of pain behaviors, including facial expression, leg movement, activity, cry, and consolability.
