Based on the observation that a profession (here taken to mean the specialized educator) cannot be reduced to an analysis of a situation in which a standard response to a task at hand can be routinely expected, the evaluation of these actors cannot be achieved by mere enumeration of a series of “adequate” responses. The evaluation of a professional who solves a complex task must be achieved by taking into account his own goals. The specialized educators are engaged in several ways, but always they have to establish activity reports. Based on these reports, four key values have been identified and introduced in a forced-choice questionnaire. By using hierarchical clustering (HCA), six ways of organizing these values emerge, constituting a number of identified systems (with meaning) that must be taken into account in the assessment of professionals. This formalization has repercussions on the initial and continued training of professionals.
