Abstarct: The difficulty of writing tasks and the high-stakes nature of IELTS lead both IELTS teachers and students towards discovering effective writing techniques. Although some techniques have been frequently discovered, incomprehensible information is available about these techniques. The current study aims at exploring IELTS writing teachers' perspectives on effective techniques and strategies in teaching writing skills. By grounded theory methodology, the researcher theoretically sampled concepts through interviewing 13 IELTS practitioners. The interviews were audio taped, transcribed, and analyzed by applying open coding, selective coding, and axial coding. In a cyclical process of data collection and analysis, the researcher found the effectiveness of writing samples as layouts; moreover, he discovered that teaching prefabricated phrases, discourse markers, writing baxsed on scoring criteria, and teaching thinking and writing ideas in target language are effective writing techniques. Some of the techniques are new in the body of the knowledge and the results are applicable for IELTS writing teachers, ELT teachers, academic writing teachers, and IELTS candidates.
