When placements are being considered for children, or indeed when the functioning of a child in care is a cause for concern, the multidisciplinary team will often turn to the psychologist for a view about this. This chapter briefly outlines the range of assessments that are undertaken by psychologists and underlines the importance of drawing together information about the child from different sources and perspectives. The field of psychological assessment is wide. This chapter draws attention to the complexities involved in the process of assessment rather than providing a detailed account of the assessment tools used.
