In 2017, the ABT certification exam changed from a two-day, three part exam to a one day exam consisting of 200 questions. While the exam is be graded as a whole, there are two, three-hour sessions to allow for a break. The new exam format is based on domains and tasks from the Practice Analysis completed in 2016. In addition, questions now have only four answer choices, rather than the five choices historically on the exam.
Please utilize the Candidate Handbook for all information regarding applications, eligibility, and exam format and administration.
Congratulations to the 138 new Diplomates of 2017. Below is follow up information related to the re-designed 2017 Certification Examination.
Standard setting is a technique used to determine the passing test score that corresponds to a minimally qualified candidate for the ABT exam. When the initial form of an examination is developed following a job analysis, a criterion referenced Standard Setting exercise is conducted. Such a study ensures that passing the examination depends on the amount of knowledge displayed, not on the population of candidates taking the exam. The standard setting process uses a committee of subject matter experts (SMEs) who are representative of the toxicology profession and come from diverse backgrounds. Under the guidance of a psychometrician, the SMEs identify the point on the theoretical continuum that separates the test taker who is minimally competent from one who is not. The participants then examine each individual item on the exam, taking into account the difficulty of each. When the process is complete, the knowledge standard is able to be translated into a passing score.
