English language teaching policies have recently become a growing concern in several countries, including Iran. Whereas several studies have noted the role of explicit policy documents and texts, fewer studies have explored the role of implicit ELT policies. This research investigates the implicit ELT policies embedded in professional practices of selected private English language publishers and institutes in Iran. The study’s qualitative data comprised documents and archival information taken from sources such as official websites, social networking accounts, catalogs, and brochures of eight prominent publishers and eight leading English language institutes. Thematic analysis of the data revealed three aspects of the publishers' activities (Nominal features, Supplementary materials, and Practical features) and four main aspects of professional practices of the language institutes (Overcategorizations, Tests, Teachers, and Coursebooks). The findings suggest that the practices of the leading publishers and institutes might act as implicit policies which would most likely provide directions for other publishers and institutes in the country to pursue and adopt. Thereby, it is suggested that instead of following pre-set accepted agendas, the leading publishers and institutes work creatively to analyze local requirements and respond to the needs of Iranian learners to enhance the status of ELT in the country.
