This article reports on the implementation of extensive reading (ER) among English teachers of secondary schools and the challenges they face as a part of their efforts in supporting the Indonesian government program of school literacy initiative (SLI). The data were obtained from an online survey to a group of English language teachers (N = 22) from 22 different schools in one regency in East Java Province, Indonesia. The survey was then followed by a focused group discussion (FGD). The results show that in general, English teachers have a relatively good knowledge of ER as one way to support the success of SLI, but not all of them implement the programs due to such challenges as lack of support from the government and school administration, the overwhelming workload, and the unavailability of ready-to-use materials and activities. There is, therefore, a definite need for the government and school administration to support the implementation of SLI through ER by giving teachers and students necessary provisions, such as graded readers and structured ER activities.
