The Music Therapy Assessment Manual: A Guide to Data-Based Decision Making focuses on assessment with an emphasis on how it plays a role during all stages of the treatment process. The manual provides guidelines on how to conduct an assessment by linking referral, initial assessment, treatment planning, progress monitoring, treatment evaluation, and termination.  It also positions the practice of assessment as a music therapist’s professional responsibility by aligning it with current standards and structures. This book is essential reading for all in the music therapy profession: students-in-training, entry-level clinicians, and experienced therapists who value and strive to implement a data-based approach to decision-making that involves grounding treatment decisions based on a wide range of accumulated evidence.
