Despite the great number of interlanguage pragmatic (ILP) studies on different speech acts, only a few studies have been conducted on the correction speech act and its production strategies. Thus, the main purpose of this study is to discover Persian speakers' corrective strategies. It also aims at comparing and contrasting Persian correction strategies with those employed by native English speakers. To these ends, 50 Iranian university students were randomly selected to complete a Discourse Completion Task (DCT) questionnaire in Persian. Twenty native English speakers were also requested to complete the same DCT questionnaire in English. The findings reveal that corrective strategies in Persian and English are formulaic in pragmatic structures. Besides some similarities between the ways of correcting in the two languages, there are also some distinctions, such as criticising and using ironic expressions and threatening the correctee, strategies used by Persian participants and correcting through compliments, a strategy that is used only by native speakers. Moreover, both Persian participants and native English speakers used more direct strategies than indirect ones. This can be attributed to the differences between cultures, interlocutors' positions and gender. This study has implications for language researchers, Iranian EFL teachers, test designers and material developers.
