A professional journal is a scholarly journal addressed to a particular professional audience such as doctors, lawyers, teachers, engineers, or accountants and published by a professional organization. They may contain research articles, reports, and practical articles applicable to the profession. They may also be referred to as practitioner journals or trade journals.
Professional journals can be a source of research for the profession, such as Reading Teacher. However, professional journals are different from peer-reviewed / scholarly journals. For more information on peer-reviewed / scholarly journals, see "How do I tell if a journal article is peer reviewed?"
