The Comprehensive Executive Function Inventory (CEFI) is a rating scale designed to measure behaviors associated with executive function for individuals ages 5 to 18. It can be completed by a parent, teacher, or self-report for ages 12 to 18. There are six versions to accommodate ratings in English or Spanish by parents, teachers, or self. Each 100-item form yields a full scale score and scores on nine content scales related to different types of executive functioning behaviors. The forms provide standardized scores with a mean of 100 and standard deviation of 15 to evaluate executive functioning.
