Gaining insights from domain experts into how they view communication in real world settings is recognized as an important authenticity consideration in the development of criteria to assess language proficiency for specific academic or occupational purposes. These "indigenous" criteria represent an articulation of the test construct and should therefore reflect what is germane to the particular domain of language use rather than general language-focused criteria familiar from other language tests. The methodological question of how to elicit such insights is, however, complex and has been addressed by various researchers using different methodological and theoretical frameworks.
