Certifying Examination

If your credentials packet has been submitted and you have been approved to take the next exam, please click below to pay exam fees and register.

All candidates seeking certification as an ACT Diplomate must take and pass a comprehensive examination in Theriogenology. The certifying examination is based on the professional competence expected of Diplomates based on a job task analysis conducted periodically by the College. The examination reflects the breadth and depth of the field of Theriogenology.

The examination is prepared by the Certifying Examination Committee. The Examination Committee maintains the examination database, composes questions, and creates and administers the certifying examination. The questions selected by the Examination Committee are then scored by an independent Angoff Scoring Committee working with the assistance of a psychometrician. The Angoff Scoring Committee sets the examination passing point. Members of the Certifying Examination Committee and Angoff Scoring Committee are appointed according to species of interest and professional affiliations to ensure diversity and balance within the committees.

The examination consists of 100 multiple-choice questions (200 points), 20 essay questions (200 points), and 45 to 50 practical questions (100 points). Candidates are expected to express themselves fully to demonstrate specialization when answering essay questions. Practical questions include pictures or short video clips that only require short answers. The examination is usually administered once each year, over two days during late summer. Specific examination dates vary from year to year. The examination is entirely in electronic format and is administered remotely using a web-based tool.

The examination covers animal species commonly seen by Diplomates. Exam specifications (blueprint) related to the distribution of assessment material according to species are:

Study Recommendations

The following recommendations are based on results of surveys conducted with ACT candidates:

  • Develop a study plan with your mentor, including topics, materials, and timelines. Agree on a system to periodically assess progress and ensure that you are on track.
  • Begin to study early during the training program and devote specific time to study. A common pitfall is to expect to have time off work just before the exam to study (cram).
  • Create study summaries such as written transcripts, flash cards, comparative tables, typed bullet points, or recorded audio notes. Review summaries closer to the exam rather than re‐reading the sources.
  • Do not rely on study groups as the primary or only means of study. It is recommended that study groups are mentored by an ACT diplomate.
  • Use textbooks as primary source of information for study. Read textbooks early on.
  • Read a wide number of journal articles. Recent review articles are good sources for the most up-to-date information on a topic.
  • With assistance from mentor, practice writing and answering essay questions, working on content, completeness, and time constraints.
  • With assistance from mentor, practice writing multiple-choice questions as a form of study.
  • If possible, arrange to visit other colleges or practices to work with species or in areas that you are unfamiliar or do not have access to at your institution or practice, to gain hands‐on experience and obtain good mentoring from persons with different expertise.
