Professional peer review focuses on the performance of professionals, with a view to improving quality, upholding standards, or providing certification. Professional peer review activity is widespread in the field of health care, where it is best termed Clinical peer review. Further, since peer review activity is commonly segmented by clinical discipline, there is also physician peer review, nursing peer review, dentistry peer review, etc. Many other professional fields have some level of peer review process: accounting, law, engineering (e.g., software peer review, technical peer review), aviation, and even forest fire management. In academia, peer review is common in decisions related to faculty advancement and tenure. Peer review is used in education to achieve certain learning objectives, particularly as a tool to reach higher order processes in the affective and cognitive domains as defined by Bloom's Taxonomy. This may take a variety of forms, including closely mimicking the scholarly peer review processes used in science and medicine.
