Whilst assessment has long been central to the counselling process, with the recent moves towards evidence-based practice and increased regulation it is taking an increasingly pivotal role in service provision. This important new text helps clarify the nature and purpose of assessment in counselling. It explores the theoretical underpinnings of assessment across the core therapeutic schools and addresses critical differences in the meanings and importance deferred to it. It will be invaluable reading for all trainees as well as for practitioners wishing to gain a broad insight into therapeutic practice across the boundaries of the many therapeutic models.
