“…Previously, the major focus was on assessment of linguistic systems via norm-referenced and standardized tests; now, however, clinical linguists and their colleagues in various disciplines of applied linguistics (e.g., speech-language pathologists, ESL teachers, educators) have become more focused on authentic speech and language data. Many of these professionals understand the limitations of normreferenced and standardized tests as descriptors of language pro ciency and they have moved progressively toward the collection and analysis of connected speech and language via sampling procedures (e.g., Halliday and Hasan, 1976;BarrieBlackley, Musselwhite and Rogister, 1978;Muma, 1978;Damico, 1985;Crystal, 1992;McTear and Condi-Ramsden, 1992;Perkins, Body and Parker, 1995;Willcox and Mogford-Bevan, 1995;Ferguson, 1996). As a result of this focus on authentic data, sampling procedures and the strategies for authentic data collection and analysis have become more important; clinical linguists are embracing rather than ignoring the complexity and synergy of linguistic and communicative data for assessment purposes and are more aware of the complexity of the procedures employed to investigate these data (Damico, 1993;Mü ller, 2000).…”
