The Strengths and Difficulties Questionnaire (SDQ) is a brief behavioural screening questionnaire. Local authorities are required to submit the scores of the carer version but there is also a version for young people (over the age of 11) and schools to complete. The triangulation of all three responses gives the most accurate picture of a looked after child’s mental health and well-being. There is also a link emerging between SDQ scores and educational outcomes, making them more significant for Virtual School Heads.
