“…Given that the kindergarten years are a critical period of growth for students' emergent-literacy, oral-language interventions placed during the course of the kindergarten school year give students an additional source of support at a critical time in their development. More importantly, research showed that a tutoring program is a key component of successful oral-language interventions (Al Otaiba, Schatschneider, & Silverman, 2005;Jordan, Snow, & Porche, 2000;Rolla San Francisco, Arias, Villers, & Snow, 2006;Vadasy, Sanders, & Peyton, 2006).
