Repair strategies are the ways in which students resolve conversational problems in speaking, hearing and understanding. While there is a plethora of research on college and adult students' repair strategies usage, limited research has been done on the repair strategies usage of elementary school students, more specifically, English as a Second Language (ESL) students. This article examines the repair strategies used by 5 ESL primary elementary students in grades 1-4. Data were collected from 24 class hours of video recordings. The results revealed that students used 9 types of repair strategies: (1) Unspecified; (2) Interrogatives; (3) (Partial) repeat; (4) Partial repeat plus question word; (5) Understanding check; (6) Requests for repetition; (7) Request for definition, translation or explanation; (8) Correction; and (9) Nonverbal strategies. Of the 9 types, students used understanding check 30% of the time and (partial) repeat 24% of the time. (Contains 1 figure and 2 tables.)
