Abstract
In this paper a number of issues are discussed relating to the assessment of hypnotism. First, some questions concerning the function of standardization and the use of norms are considered. Next, a relatively neutral definition of hypnotic susceptibility is proposed as a context within which important variations in its assessment are subsequently discussed. These variations are grouped according to whether they concern context, content, internal structure or external relations. A final section considers the enterprise of hypnotic state assessment.
