Plain Language Summary 
Parents of children with communication problems cannot sometimes use language strategies efficiently while interacting with their children. So, it may affect the children’s communication skills in the natural environment. A model called Teach-Model-Coach-Review that follows the principles of milieu teaching makes the parents’ education more systematic and comprehensive. The current study adopted this model to Iranian society to provide Iranian speech therapists with the first systematic protocol for parents, whose children’s expressive language is delayed. The language strategies that were targeted in this study included noticing and responding, turn-taking, and expanding.Four children with their mothers attended a series of speech therapy sessions. We asked the mothers to look at different strategies modeled by the clinician. Then, they were asked to react to each strategy, and they were coached during performing strategies with their children. All steps were video-recorded and, finally, the clinician reviewed all steps with the mother by watching the recordings and provided feedback to the mothers. Iranian mothers learned and used all language strategies with high levels of accuracy and their children showed improvements in vocabulary targets. Hence, it is suggested that Iranian speech therapists implement this model in clinical settings to make the parents’ education more systematic and effective.
