the SASS teacher questionnaire were analyzed to address the endeavor. Teachers' perception of preparedness is manifested by the following areas: (a) classroom management, (b) instructional methods, (c) teaching subject matter, (d) assessing students, (e) differentiating instruction, and (f) using assessment data to inform instruction. The following research questions were asked:1. Do teacher perceptions of preparedness vary between ELL teachers, mainstream classroom teachers with ELL teachers in the classroom, and mainstream classroom teachers without ELLs? 2. Do ELL teachers perceptions of preparedness vary across grade levels (elementary and secondary)? 3. Do teacher perceptions of preparedness relate to their training (i.e, length of student teaching, number of method courses during teacher education program, and highest degree earned)? Theoretical Framework The achievement gaps between ELLs and their peers in reading and math across the nation present early when children enter school, tends to widen at higher grade levels, and persists even when they are no longer identified as ELLs (de Jong, 2004;Mulligan, et al., 2012). A significant proportion of ELLs is characterized as low achievers, has high dropout rates, and grade retention (Hodgkinson, 2003; NCES, 2017). The percentage of ELLs in Public schools in the U.S. has been increasing, (NCES, 2017;Soto, Hooker, & Batalova, 2015). The teacher workforce in the U.S., however, is not as culturally and linguistically diverse as the student population (ECES, 2017). For instance, in 2011-12 academic year, about 82% of public school teachers are white whereas the public students of white were only 51% (King, et al., 2016). Moreover, there has been insufficient growth of teachers understanding about best practices to educate ELL students (Wessels et al., 2017). This implies a great need for studies that investigate the effectiveness of teacher preparation programs as well as teacher preparedness about working with ELLs. The inequity issues in our school with ELLs could be further understood from the perspective of teacher quality in the classroom. This study interrogates public school teachers' preparedness during their first years of teaching for these demographic changes.Prior research suggests that teachers' feelings of preparedness may differ by whether they work with ELLs (De Jong & Harper, 2005;del Rosal et al., 2018;Gandara et al., 2005;Reeves, 2009). Research has also shown that teachers are not being prepared to meet the needs for a diverse population in US classrooms today (e.g., Robertstein and Lee, 2014). In fact, most teacher education programs and curricula have not changed over the years, even though significant changes in legislation, instructional programs, and instructional approaches for ELLs have been made (De Jong & Harper, 2005; Gándara, Maxwell-Jolly, & Rumberger, 2006). Teacher attitudes toward ELLs affect students' outcomes and teacher feelings of preparedness to work with ELLs. However, inadequacies have been reflected differently among teach...
