Abstract

Objectives: The present study investigates which information obtained by three tasks?language survey, standardized tests, and language sample analysis (LSA)?best predicts language proficiency in children or adults from culturally and linguistically diverse (CLD) backgrounds.
Methods: Korean-English bilingual children and adults were given a language survey and two standardized tests for articulatory accuracy and lexical abilities. Utterances for LSA were analyzed using the Systematic Analysis of Language Transcripts and compared to Korean monolinguals and English monolinguals (EMs).
Results: The number of mazes, the number of abandoned utterances and words per minute (WPM) were significantly different from the age- and utterance-matched EMs. Perceived English proficiency in children was correlated with age of arrival, length of residence, performance on Goldman-Fristoe Test of Articulation-2 and Expressive Vocabulary Test, and the number of grammatical errors. Self-reported proficiency in adults was correlated only with mean length of utterance (MLU). The results also indicated that language measures, such as the number of total words (NTW) and the number of different words (NDW), MLU, and WPM, were closely related to one another.
Conclusion: Based on the results of the present and previous studies, it is desirable for speech-language pathologists (SLPs) to evaluate at least NDW, NTW, MLU, and WPM from language samples when assessing individuals from CLD backgrounds. Clinical implications to help SLPs develop their own feasible yet reliable procedures for conducting language survey and LSA were discussed.
