he introduction of free, online training in Good Clinical Practice (GCP) was introduced in 2016 by the Research and Education Training Program (RETP), an enabling platform of the Western Australian Health Translation Network (WAHTN) for health and medical research professionals. The modules are accessible to all staff and students within the 21 WAHTN partner institutions (including all major hospitals and universities) in the state of Western Australia. This report evaluates perceptions of the online participants of the GCP modules. After completing the GCP course, each participant was given an evaluation asking their opinion about the modules. Underpinned by a mixed-method approach, a multi-level analysis assisted the RETP to identify aspects which called for sustainable maintenance and improvement for improved delivery. Over 90 users participated in the online training. A case example describes that both of qualitative and quantitative data were useful to provide possible improvements within the course content presentation, technical issues, and management and operation issues.
