About this exam

The CGC credential is a genetic counseling certification mark conferred by the American Board of Genetic Counseling (ABGC) after a candidate passes the ABGC certification exam. ABGC states that the CGC mark may only be used by an individual who holds a valid, current CGC credential, conferred after passing the ABGC certification exam, and that use of the ABGC or CGC acronym requires ABGC's prior, express written permission. The credential is aimed at genetic counselors who have completed ABGC-eligible training and wish to be certified; ABGC publishes separate Eligibility Requirements and a Certification Process, Exam and Fees page, and directs candidates to its Candidate Guide for instructions on completing the application, paying examination fees and scheduling an appointment to test. The exam is multiple choice, and ABGC offers a practice exam described as designed to mimic the real test. ABGC's Exam Resources page also links a Content Outline, a Study Guide, an Exam References list, advice from CGCs and a student webinar, which are the appropriate starting points for preparation. This page is an independent study resource and is not affiliated with, endorsed by, or approved by ABGC; ABGC states it does not endorse, sponsor, affiliate with, or approve any outside exam preparation products or courses. Always confirm current exam details on ABGC's own pages.

What you'll study

Common questions

About CGC preparation

What is the format of the CGC exam?

ABGC lists the exam as multiple choice and provides a practice exam described as designed to mimic the real test. ABGC does not state a question count, section structure or time limit on the pages summarized here, so check the Candidate Guide and the Certification Process, Exam and Fees page for the current specifications before you plan your test-day pacing.

How many questions are on the exam and how long do I have?

Those figures are not stated in the ABGC pages summarized here, so treat any number you hear from other candidates with caution. The authoritative sources are ABGC's Certification Process, Exam and Fees page and the Candidate Guide PDF, which ABGC says covers applying, paying fees and scheduling an appointment. Verify there before building a timed practice plan.

What score do I need to pass?

The passing standard is not given in the ABGC material summarized here, and it should not be assumed from other exams or from older recollection. Consult the Candidate Guide and the Certification Process, Exam and Fees page for the current passing standard and scoring approach. Aim to master the Content Outline domains rather than targeting a guessed percentage.

What does the exam cover?

ABGC publishes a Content Outline PDF under Exam Resources, and that document is the only reliable statement of domains and their weighting. Download it and map every topic to a study block. This page's domain breakdown is provisional because ABGC's official outline was not retrievable in the source material used here, so do not rely on it for planning.

How much does the exam cost, and can I get help paying?

Fees are set out on ABGC's Certification Process, Exam and Fees page and in the Candidate Guide; no amount is stated in the material summarized here. ABGC also lists a Need-Based Certification Scholarship under its Certify menu, which is worth reviewing early because scholarship timing may affect when you apply for an exam window.

If I fail, can I retake the exam?

The retake policy is not stated in the ABGC pages summarized here, so confirm it directly with ABGC before you rely on a repeat attempt. Practically, candidates who do not pass should request their score information, identify the weakest Content Outline domains, and rebuild study around those areas rather than repeating the same preparation.

How should I order my studying?

Start with the Content Outline, then read the Study Guide and the Exam References list to bound what is testable. Study high-weight domains first, then integrate cases across domains, since genetic counseling questions rarely test isolated facts. Finish with the ABGC practice exam to rehearse the multiple-choice format and to expose remaining gaps.

What are the most common ways candidates lose points?

Typical failure modes are knowing facts but not applying them to a scenario, skipping the risk-assessment and counseling-process steps in a case, misreading questions that ask for the best next step, and never rehearsing under time pressure. Others study only from memory-based resources instead of the ABGC Content Outline and Exam References list.

Is this site affiliated with ABGC?

No. This is an independent study resource and is not affiliated with, endorsed by, or approved by ABGC. ABGC states that it does not endorse, sponsor, affiliate with, or approve any outside exam preparation products or courses, and that use of the ABGC or CGC acronym requires its prior express written permission.

How do I apply and schedule a test appointment?

ABGC directs candidates to its Candidate Guide for instructions to complete the application process, pay examination fees, and schedule an appointment to take the ABGC Examination, and to the Application Portal for submitting an application. Start there rather than with third-party scheduling advice, and confirm eligibility requirements before applying.
