This article promotes integrating assessment and evidence-based practice in the treatment of traumatized children through a review of two newly developed trauma assessment tools: (1) the Child Welfare Trauma Referral Tool (CWT), and (2) Assessment-Based Treatment for Traumatized Children: A Trauma Assessment Pathway Model (TAP). These tools use pathways and algorithms to increase understanding of individual child trauma victims, and assist professionals working with children to make appropriate referral and treatment decisions within both child welfare and mental health contexts.
