RESUMO
The American Board of Toxicology (ABT), in consultation with ACT Credentialing & Career Services (ACT), performed a practice analysis study of general toxicology in 2020-21. This work follows up on an initial practice analysis commissioned by the ABT and conducted in 2014-2015, results of which were published in 2016. The purpose of the current, second-generation study was to update and validate the existing process-based delineation of practice of general toxicologists, including major domains of responsibility and tasks performed in practice. In addition, the study included the review, update, and validation of the knowledge areas required by toxicologists developed by subject-matter experts (SMEs) that have been used for ABT examination development initiatives. Consistent with best practices in the field of credentialing, ABT also contracted with ACT to conduct 2 follow-on activities: a study to evaluate the reliability of a reduced-length ABT examination and a standard setting study to establish a valid passing score for the updated examination. In addition to informing ongoing ABT certification examination and question writing activities, it is anticipated that the results of this practice analysis will be of value to those responsible for developing graduate and undergraduate toxicology curricula, creating continuing education content, and authoring textbooks covering the contemporary practice of toxicology.
