EXAM OVERVIEW
This comprehensive ABRET EEG Exam Test Bank contains 150 multiple-choice questions aligned with the
2026-2027 ABRET (American Board of Registration of Electroencephalographic and Evoked Potential
Technologists) EEG Board Certification Examination Content Outline. Each question has been crafted to mirror the
format, style, and difficulty level of actual ABRET board examination questions, with all answers verified for clinical
accuracy.
STRUCTURE
The exam is organized into eight (8) content sections, each covering a major domain of neurodiagnostic practice as
defined by the ABRET content outline. Questions are numbered sequentially from Q1 through Q150 to maintain
continuity across sections. Each question presents four (4) options (A-D) with exactly one (1) correct answer.
Section Topic Question Range
1 EEG Instrumentation and Electronics Q1 - Q25
2 Normal EEG Patterns and Variants Q26 - Q45
3 Abnormal EEG Patterns Q46 - Q70
4 Seizure Disorders and Epilepsy Syndromes Q71 - Q90
5 EEG in Special Populations Q91 - Q110
6 Evoked Potentials and Neurodiagnostic Procedures Q111 - Q125
7 Patient Care, Safety, and Ethical Considerations Q126 - Q140
8 EEG Interpretation, Reporting, and Clinical Correlation Q141 - Q150
HOW TO USE THIS TEST BANK
Each question includes a detailed rationale explaining why the correct answer is right and why the other options are
wrong, including clinical significance, waveform identification principles, instrumentation concepts, and patient
safety considerations. The correct answer is highlighted with a green background and a [CORRECT] marker for easy
review. This format enables both self-assessment and focused study of specific content areas.
COGNITIVE LEVEL DISTRIBUTION
The question set reflects the ABRET cognitive level distribution: approximately 30% recall (factual knowledge), 45%
application (using knowledge in clinical scenarios), and 25% analysis (integrating information for problem-solving).

This distribution mirrors the actual board examination and ensures comprehensive preparation across all cognitive
domains.
SPECIAL FEATURES
Questions incorporate real exam-style scenarios including EEG tracing descriptions, 10-20 System electrode
localization exercises, differential diagnosis integration with clinical history, time-sensitive clinical scenarios, and
image-based descriptions simulating actual ABRET board formats. Distractors are crafted to represent common
ABRET exam pitfalls encountered in actual board examinations.

SECTION 1: Section 1: EEG Instrumentation and Electronics
Filters, Montages, Calibration, Impedance, and Artifact Recognition
Q1: A differential amplifier in EEG recording amplifies the difference between two inputs while rejecting
signals common to both. Which specification best describes the amplifier's ability to reject common-mode
signals such as 60 Hz environmental noise?
A. Common-mode rejection ratio (CMRR) of 60 dB, meaning common signals are reduced 1000-fold
B. Common-mode rejection ratio (CMRR) of 80 dB or greater, meaning common signals are reduced
10,000-fold or more [CORRECT]
C. Signal-to-noise ratio of 80 dB
D. Input impedance of at least 100 megohms
Correct Answer: B
Rationale: The differential amplifier's ability to reject signals common to both inputs (Input 1 and Input 2) is quantified by
the Common-Mode Rejection Ratio (CMRR), expressed in decibels (dB). A CMRR of 80 dB or greater is the
ABRET-accepted standard, meaning common-mode signals are reduced by a factor of 10,000:1 (20 log10(10,000) = 80 dB).
A CMRR of only 60 dB reduces common signals 1,000-fold, which is inadequate for clinical EEG where 60 Hz noise often
exceeds the EEG signal. Signal-to-noise ratio and input impedance, while important amplifier characteristics, do not measure
common-mode rejection.
Q2: During a routine EEG recording, the technologist notes persistent 60 Hz artifact affecting all channels.
After verifying electrode impedances are below 5 kOhms, which filter adjustment is most appropriate to
eliminate this artifact while preserving EEG signal integrity?
A. Apply a 60 Hz notch filter as the first-line intervention [CORRECT]
B. Increase the low frequency filter (LFF) to 5 Hz
C. Decrease the high frequency filter (HFF) to 15 Hz
D. Increase sensitivity to 30 uV/mm
Correct Answer: A
Rationale: When 60 Hz artifact persists despite acceptable electrode impedances (typically below 5 kOhms), the appropriate
intervention is application of a 60 Hz notch filter, which selectively attenuates signals at 60 Hz while leaving surrounding
frequencies largely unaffected. This is preferred over adjusting LFF or HFF, which would distort physiologic slow and fast
activity respectively. The notch filter should not be used routinely, however, as it can mask electrode artifacts that mimic 60
Hz activity and may distort spikes and sharp waves that contain frequency components near 60 Hz. Increasing sensitivity
would make the artifact more visible, not less.
