The Standard English Repetition Test (SERT) is an instrument designed to measure the Standard English (SE) performance of young Hawaii Creole English (HCE)-speaking children. HCE is colloquially referred to as "pidgin English." Details of the test's construction are given; test-retest and alternate form reliability and validity studies are presented. The test employs the technique of controlled, elicited imitation, which requires the child to repeat SE sentences spoken to him by an adult examiner. The method is based on the assumption that a child who understands a sentence--who is familiar with its syntax, phonology, and vocabulary--will be likely to repeat the sentence accurately. Correlates of individual differences in SE performance are presented for one sample of HCE-speaking children. Possible uses of the test include further research on the relationship between academic achievement and Standard English proficiency, and developmental studies of HCE speakers as they progress through elementary school.
