Their behaviors were video-recorded, and the percentages of mother&rsquo;s behaviors were calculated. Visual analysis and an Improvement Rate Difference (IRD) metric were provided to document the mothers&rsquo; progress. Fidelity was checked, using a checklist of items taught by the clinician, as well as a quality check of the sessions.<br> <strong>Results</strong>: Mothers indicated the improved levels of strategy usage after receiving EMT and maintained their skills at criterion levels after the termination of the intervention. IRD for notice-respond, turn-taking, and expanding was 0.88, 0.91, and 0.88 for FA&rsquo;s mother, respectively. IRD was 0.92 and 1 for AM&rsquo;s mother. The two strategies of notice-response and turn-taking showed IRDs of 1 and 0.66 for KA&rsquo;s mother.<br> <strong>Discussion</strong>: Iranian speech therapists employ a Persian-adapted edition of the Teach-Model-Coach-Review model of EMT with confidence to follow the improvement of parents&rsquo; strategies usage within an early intervention course of management of child language delay. The model provides a systematic education of parents to address the communication needs of their children.</div> Language delay, Early intervention, Parenthood education, Milieu therapy 99 112 http://irj.uswr.ac.ir/browse.php?a_code=A-10-930-1&slc_lang=en&sid=1 Yalda Kazemi kazemi@rehab.mui.ac.ir 0000-0002-9829-7046 Yes Child Language Research Cluster, Department of Speech Therapy, School of Rehabilitation Sciences, Isfahan University of Medical Sciences, Isfahan, Iran.
