This chapter focuses on the relationship with committees responsible for ethical approval of research projects. This ethical conduct in turn determines not only the type and reliability of evidence, but significantly impacts both professionals and service users as participants in and consumers of research. The chapter argues that it is important to inculcate ethical research conduct in the professional conduct of some professions to ensure that professional ethical codes are both practical and applicable for research. For professional ethics to be considered as beneficial in the conduct of research in practice, educators need to ensure that students develop critical thinking skills so that they are able to make good ethical decisions and not rely on personal values in the consideration of vulnerability, harm, informed consent, and conflicts of interest. The ethical review process clearly raises questions about partnerships between communities, researchers and ethical review communities and the unintentional harm that may occur in the process.
