Item writing and reviewing are essential components of the exam development process that involves subject matter experts (SMEs) writing and reviewing test questions or items for future use on the ATCBE examination. These items are crafted to ensure they accurately assess the knowledge and competencies relevant to the appropriate certification exam. Guided by ATCB’s Psychometrician and assessments team at Prometric, item writers will be tasked with authoring and reviewing test questions. SMEs will undergo specialized web-based training to learn how to write and review items for certification exams, ensuring the items developed are high quality and meet the standards required for high-stakes examinations. Becoming an item writer provides a platform to contribute to the field directly and is a gateway to further volunteer opportunities within ATCB. Participation as an item writer is recognized with continuing education credits that can be used towards Maintenance of the BC Certification.
