Screening is a process for evaluating the possible presence of a particular problem. The outcome is normally a simple yes or no. Assessment is a process for defining the nature of that problem, determining a diagnosis, and developing specific treatment recommendations for addressing the problem or diagnosis.
A positive result on a screening tool should result in a referral for a more thorough assessment. The CEBC defines an assessment tool as an in depth process used to understand a childâs and/or familyâs strengths and needs, such as functioning, family and individual history, symptoms, and the impact of trauma.
