Creativity tests including the Torrance Test of Creative Thinking (TTCT), the Alternative Use Test (ALT) and the Remote Associates Test (RAT) require written communication. This paper examines the relationship between language and creative abilities with English as Second Language (ESL) and Native Speakers of English (NSE). The TTCT, ALT and RAT were used as measures of creative ability of 194 students. A self-rating of English ability was used as a measurement of language mastery. English ability of ESL students was significantly positively correlated with the more verbal test scores (ALT, P=0.029; RAT, P=0.006). In the TTCT, there was no strong correlation between self-rating of English ability and creativity scores. However, ESL students in general had statistically significant lower TTCT scores than NSE students (F=0.055, P=0.002).
