The purpose of this interpretative phenomenological study was to explore perceptions of teachers of the deaf (TOD) about services delivered to students with hearing loss, how those services impact the deaf or hard of hearing (D/HH) students' transition post-high school, and what training supports need to be provided to teachers so they can assist D/HH students with accessing the general education curriculum. Three research questions addressed were: 1. What are the perceptions of high school teachers of the deaf of the transitioning programs from a high school setting to post-secondary life? 2. How do teachers of the deaf determine the appropriate duration of services allocated to support students with hearing loss within the high-school setting structure that supports the transition to college readiness or work placement? 3. What is the relationship between IEP goals and objectives and their use in supporting the transition of students with hearing loss as they enter college or a work setting? Participants of the study were high school teachers of the deaf who have experience with a transition within a variety of D/HH student placements. Data was collected via interviews using ZOOM, and interview data were transcribed. An analysis was conducted to determine predominant themes based on the interview data. Findings indicated the importance of TODs, their perceptions of transition support and the need for improvement, and the impact parents have on a student's overall success. This study explored considerations of the IEP planning process and its overall impact on a student's post-graduation opportunities. The study results suggest the need for a consistent assessment protocol, improved methods for collaboration with parents, and strengthened communication with workforce resources.
