Plagiarism is a highly discussed issue in higher education institutions in recent times. Turnitin text-matching software has widely been adopted by many academic institutions in Ghana as one of the solutions to improving students' and faculty academic writing and a solution for detecting incidences of plagiarism. There has been little empirical research into what students actually know about plagiarism and their lived experiences of text-matching technology, despite the fact that a lot of research has looked at attitudes, motivations, and demographic characteristics related to academic dishonesty. This study used an online Google form for data collection. We enrolled 1054 postgraduate students of the University of Cape Coast. The data collected was analyzed using SPSS version 21.0, and the proposed hypothesis was tested using Structural Equation Modeling. Findings show that there was no statistically significant relationship between postgraduate students' academic levels and their perception of plagiarism. However, there is significant relationship between postgraduate students' perception of plagiarism and their use of Turnitin. There is also statistically significant relationship between postgraduate students' awareness of Turnitin and its use. This calls for increased awareness creation and sensitization, which can be accomplished through scientific writing workshops, focused on inculcating ethical research practices into students.
