Disclosure
The material presented today best
represents the current thoughts and
processes in developing the Core and
Certifying exams of the ABR.
What We’ve Done Until Now
Two comprehensive written examinations
Physics (first offered September 2nd year)
Diagnostic (first offered September 3rd year)
Candidates must pass both to qualify
One comprehensive oral examination
First offered in June of 4th year
11 categories examined
Written Examinations:
Details Physics
Diagnostic, Nuclear, Radiobiology
Recall and application of physics concepts
No associated images
Diagnostic ~20 MCQs in each category
Evaluated information recall
No associated images
Scored as a whole (not by category)
Written Examinations:
More Details Criterion-based exams
Theoretically, failure rate could be 0-100%
Failure rates (first-time takers):
Physics: 10-15%
Diagnostic: 8-10%
Both exams offered retake opportunities
Oral Examinations:
Details 25 minute oral examinations
Centered on specific case images
Minimal fact recall
Focus on observation, synthesis, management
Communication skills and judgment paramount
Specific diagnosis less important than
logical approach
Oral Examination:
More Details Criterion-based exam
Complex grading system Each candidate discussed in detail
Potential for raising marginally failing scores
Could fail 1-3 categories, but must re-test
Statistics for first-time takers: Pass: 85%
Fail: 5-7%
Condition: 8-10%
Criticisms of Examination Process:
Written Exams Physics examination better suited to physics
students, not radiologists
Rarely relevant to everyday practice
Diagnostic exam:
No images
Fact retrieval (trivia?) only
Not scored categorically—candidates could pass
knowing nothing about (fill in the blank)
Criticisms of Examination Process:
Oral Exams Subjective
No two tests the same
For some candidates, pathologically stressful
Exam reliability incalculable
Expensive
For ABR: ~400 examiners X 5 days
For candidates: single inconvenient location
Response by the ABR:
Changes in Exam Structure Qualifying (Core) exam:
Comprehensive: Covers all of diagnostic radiology Includes physics, patient safety, noninterpretive
Categorical: candidates must pass all sections Candidates and training programs receive data Opportunities for retakes: every six months
Knowledge level: basic to intermediate Appropriate for ending third year resident Timed for June of third year (except 2013) About 40% fact recall, 60% higher-level evaluation

Core Exam Certifying
Exam
Core Exam in Diagnostic Radiology
Will be given September 30-October 4, 2013
Subsequent years will be offered in late June
Last full Oral exam in June, 2013
Covers all of diagnostic radiology
Comprehensive, categorical exam
Candidates must pass all categories
What Are These Categories?
Organ
systems
MSK, Thoracic, GI, Urinary, Neuro, Pediatrics, Cardiac,
Reproductive/Endocrine, Mammography, Vascular
Modalities CT, MRI, RF/Fluoro, Nucs, Interventional, Ultrasound
Fundamentals Physics, Safety
Exam Goals: Core Overarching goal: to protect the public by determining that
individual candidates have attained competence in basic diagnostic radiology
Specific goal: to create examinations that are relevant to current radiologic practice
Specific goal: to make a reliable pass/fail decision about candidate performance in each category For this high-stakes exam, reliability requires ~60 questions/category
Emphasis on unique importance of Physics content = 110 questions

~40% fact recall (like current written)
~60% higher level (like current oral)
Differential diagnosis

Core Exam 2013+
Nuts and Bolts ~660 items
Two half day sessions during a single week
Examination center(s)
One large Chicago center
Smaller center in Tucson
ABR commitment: distributed exam by 2018
Condition exams June/October
5440 N. Cumberland Ave., 4½ miles and the second train stop
on the CTA Blue Line from O’Hare Airport. ~30,000 square feet
ABR FastPass Palm Vein Biometrics
Results: Test Scoring
Each category (18) will be scored separately
Score will be based on pre-test assessment of item difficulty (Angoff method)
Each test item will be scrutinized for its performance (p-value, r-value), and adjustments made for problem items
Three possible results: Pass (all 18 categories passed)—qualify for Certifying
Fail (6 or more categories failed)—must retake whole exam
Condition (1 to 5 categories failed)—must retake those categories failed
Core Examination:
Impact on Training
Candidates must be exposed to all basic
diagnostic radiology by end of third year
“Core anxiety” and review sessions will
occur early in third year
Content of review sessions will change
Core Exam: Review Sessions
Physics content Should focus on practical applications
Physics resource: rsna.org/education/physics.cfm
Diagnostic content 40% fact recall—even though image-rich, reasonable to
study topics prevalent on previous written exam
60% resembles oral boards—standard board review
Resource: Core study guide on theABR.org
Resource to come: practice exam—90 minute simulation
Practice Exam
• A taste of the full exam
• Shortened version of all sections
• A WIP
• To be on line by end of 2012
• 90 minutes -- to simulate the real exam
RSNA/AAPM Physics Modules
47 complete
30,081 enrolled, 10,467 completed
Popular modules: Basic Radiation Biology
Basic concepts in Radiography
Radiation Effects
Basic Principles of Nuclear Magnetic Resonance
Atoms, Radiation and Radioactivity

Piloting the Core Exam
First core pilot: May, 2011
Aims:
Nuts and bolts: software, image quality, time
allotted, interface
Psychometric item data: p, r values; reliability
First Core Pilot
Population: Residents taking Oral Exam
Incentive: Passing score on electronic exam
could raise condition in that category
Caveat: Would not raise if 68 on Oral
Would not raise if failed ≥ 4 categories
Only six categories: MSK, Neuro, VIR, Peds,
Breast and Cardiac
Core Pilot: Results
1117 (81.5%) took exam
Neuro 26%, Breast 7%, rest ~18%
Post-test survey: good questions, enough
time, appropriate difficulty, interface good
2nd Core Pilot
• Population: 4th year residents taking Orals
• Was given at this years May Oral exams
• Two categories were offered
• One was chosen by ABR and other was
candidates choice
• Can be used to raise 2 sections in Orals
2nd Core Pilot
• 1340 (92.5%) took exam
• Neuro and Nucs,12%;Thoracic,GI,MSK9%
• Peds, VIR 8%;GU, Breast 7%
• Repro/Endo 5%
Next Expanded Core Pilot • Full Exam to be given to PGY4 residents in ~ June 2013
• Will be given at both Chicago and Tucson
• Will try to accommodate all residents
• Feedback will be given to help guide exam to be taken in
September.
• Does NOT Count in place of real exam
• For now a one time only event in 2013
Core Exam: How Are We Doing?
13 item-writing committees (physicist
embedded in each)

All study guides completed and revised X 1
After the Core
Candidates can decide (within constraints of
their chosen training program) on their
future practice
General vs. subspecialized
Which subspecialty(ies)
Begin the process of continuous learning
Certifying Exam in Diagnostic Radiology
Will be first administered in October, 2015
Contains five parts (but questions will appear in random order)
Non interpretive skills Things every physician
should know
Essentials Things every diagnostic
radiologist should know
Clinical Practice Areas
(3 self-selected CPAs)
Things this specific
radiologist should know
Clinical Practice Areas (CPA) Twelve categories
Organ system: MSK, Cardiac, Thoracic, GI, Urinary, Neuro, Peds, Breast
Technology: US, VIR, Nuclear Radiology
General
Candidates can choose any combination of CPAs
Items will vary in both difficulty and scope Level 1: fundamental
Level 2: advanced
Candidates selecting a CPA more than once will receive a higher proportion of level 2 items
Certifying Exam: Content (CPA)
Emulates clinical practice Will include normals and variants
Will include important findings outside chosen area
Appropriateness, clinical vignettes, management decisions
Item types Familiar: MCQs, extended matching
Unfamiliar*: Structured reporting, script concordance testing
*Examples posted on ABR Website >1 year before use
Certifying Exam: Goals
To confirm candidate has acquired and
maintained necessary skills to practice
independently
Dual role
