The purpose of this qualitative single case study was to understand how co-teachers at Apple Valley Elementary School described their activities and experiences with the instructional strategy known as co-teaching. Participants of this study included three co-teaching teams. Each co-teaching team consisted of one regular education and one special education teacher at the elementary school level. Both observations and interviews were utilized to gather data about the participants' experiences and activities related to co-teaching. Pattern and In Vivo Coding was then utilized to analyze the data. After careful analyzation, the following five major findings emerged: 1) Strong relationships between co-teachers, colleagues, administration, and parents are essential. 2) Ongoing communication between co-teaching partners, administrators, parents, and colleagues is imperative for supporting co-teaching practices. 3) More professional development should be provided for co-teachers. 4) Administrators and teachers should consider the students and their abilities when deciding their placement in a co-taught classroom. 5) A clear definition of what co-teaching is and looks like at Apple Valley Elementary School should be established. This study may be helpful to administrators and teachers who are seeking to improve co-teaching at their school.
