G theory allows examination of the relationship between score variation and language variation (e.g., variation of proficiency across languages, language modes, and social contexts).

Discusses ways in which adopting cultural validity as a criterion for test validity makes it necessary to shift assessment paradigms and adopt new procedures for…

Examines the reliability and validity of the assessments as well as the comparability of the assessments generated with the shell. Contains 48 references. (Author/WRM)
