Knowledge to review for the GERO-BC exam
These foundations support the practical tasks in the official examination matrix.
Age-sensitive assessment
- Physical, psychosocial, cognitive, functional, sensory, fall, mood, skin, and abuse assessment
- Normal aging, atypical presentation, comorbidity, frailty, and disease progression
- Medication reconciliation, polypharmacy, interactions, adherence, and diagnostic-data interpretation
Individualized gerontological care
- Prioritization, safety, environment, pain, mobility, nutrition, continence, cognition, and behavior
- Medication modification, Beers considerations, nonpharmacologic care, and contraindications
- Caregiver support, case management, care transitions, palliation, and resources
Professional foundation
- Prevention, screening, education, adult learning, self-management, and communication barriers
- Ethics, advance directives, advocacy, standards, regulation, quality, and research
- Equity, special populations, telehealth, monitoring, data, and hospital-at-home care

The percentages below are the approximate exam-score weights published by American Nurses Credentialing Center (ANCC). Use them to allocate study time, then adjust for your own weak areas.
31%
Assessment and Diagnosis
Assess physical, cognitive, psychosocial, functional, medication, safety, and social factors in older adults.
- Differentiate age-related change, illness, delirium, dementia, depression, and functional decline
- Assess falls, skin, nutrition, sensory change, abuse, adherence, and social determinants
- Reconcile medications and interpret data considering aging, hydration, cognition, and disease
34%
Planning, Implementation, and Evaluation
Deliver preference-sensitive, safe, evidence-based gerontological care and evaluate response across the continuum.
- Prioritize problems and create realistic outcomes with the older adult and caregivers
- Modify medicines, routes, environment, teaching, and interventions for geriatric risks
- Coordinate transitions and supports, reassess response, and revise the plan
35%
Professional Foundation
Apply prevention, education, equity, ethics, advocacy, technology, research, regulation, and quality to older-adult care.
- Promote screening, vaccination, self-management, and healthy aging
- Address communication, diversity, vulnerable subpopulations, legal and ethical issues
- Use standards, evidence, regulation, quality methods, telehealth, monitoring, and data
How to use this GERO-BC diagnostic
After each question, identify whether the issue was normal aging versus pathology, geriatric syndrome, medication risk, function, cognition, safety, patient preference, transition, caregiver support, professional requirement, or population equity.
High-yield GERO-BC study priorities
Priority 1
Distinguish delirium, dementia, and depression
Use onset, course, attention, consciousness, cognition, function, medication exposure, illness, and collateral history rather than a single screening score.
Priority 2
Make function a vital outcome
Connect each disease and intervention with mobility, ADLs, cognition, safety, independence, caregiver burden, and quality of life.
Priority 3
Practise medication simplification
Review indication, benefit horizon, duplication, interaction, anticholinergic burden, renal function, falls, adherence, monitoring, and deprescribing.
Priority 4
Balance safety with autonomy
Apply capacity, preferences, least-restrictive care, advance directives, family roles, ethics, and risk without defaulting to paternalism.

Who should verify eligibility for GERO-BC?
Candidates should confirm the current license, education, practice-hour, role, and continuing-education requirements on the official ANCC page before applying. This study page does not determine eligibility.
How is the GERO-BC exam delivered?
