This study explored the effects of explicit and implicit instructions in the development of EFL learners' speech acts of complimenting (Cs) and complimenting response (CRs). The participants in this research were 56 intermediate EFL learners from a language center, participating as members of intact classes that were divided into three groups of control, explicit instruction, and implicit instruction. They were asked to answer an open-ended Discourse Completion Test (DCT) to collect the primary data in the pre-test and post-test sessions. The items in the DCT included 12 situations based on which the participants were required to give or respond to compliments to evaluate their knowledge of Cs and CRs. Then their responses were collected, tabulated, and analyzed. The treatment including explicit and implicit instructions on pragmatic competence lasted for three weeks after which all groups were given the DCT in post-test to measure their pragmatic competence. The results of the study highlighted the effectiveness of both implicit and explicit instructions in developing EFL learners' speech acts of Cs and CRs. It seems that pragmatic instruction regardless of type speeds up the process of learning through consciousness rising and should be considered by language teachers as one of the ways in which EFL learners can most efficiently develop pragmatic competence.
