"Hogg and Langa have assembled a gem... they have captured a range of nuanced issues and problems facing workers in the field of intellectual disabilities. This text is sure to become an indispensable companion to any clinician, researcher, or provider wanting to better understand assessment and the complex lives of people with intellectual disabilities." Matthew P. Janicki, Ph.D., University of Illinois at Chicago "A timely publication that brings together a group of highly respected contributors from Europe, North America and Australia. Its strength lies in its coverage of important conceptual issues, including person-centred planning, supported by a critical analysis of contemporary strategies and assessment instruments. The focus on person-centred planning ensures its relevance to emerging practices in the support of people with an intellectual disability. It will find a place in the libraries of both practitioners and researchers." Professor Trevor R. Parmenter, Foundation Chair of Developmental Disability, University of Sydney "This is a thought-provoking review of current assessment practice, reflecting the shift towards person-centred approaches and a concern to make assessment secure better lives for people with intellectual disabilities." Professor Jim Mansell, Tizard Centre, University of Kent at Canterbury
