This descriptive case study delved into the perceptions of Dual Certification Practicum students. The researcher examined the insight of the preservice teachers with regards to the practicum course. The Participants are three Southwestern University students that are enrolled in the Bachelor of Science Elementary Education program. The students selected have completed three semesters of practicum. Data was collected through a Venn Diagram, focused questionnaire, interview and artifacts from the student's practicum experiences. The data analysis process utilized first cycle coding for the Venn Diagram. The focused questionnaire, artifacts and the interview were analyzed through multiple cycles of coding. The data collection tools scaffold the Participants' memories of their different practicum courses to expose the results. The findings revealed that the mentor teacher is influential when it comes to the perceptions of the practicum course. Each student had different experiences during their practicum course but in the end the mentor teachers' approach to the student outlined how the course proceeded. This document provides a narrative of the students' individual experiences in practicum and the multiple connections that lead back to the mentor teacher's influence.
