CHDA Exam Study Guide

Pass the CHDA by working the way a health data analyst actually works — framing a business question, pulling the right data from the right source system, checking whether it can carry the weight of the analysis, choosing a test that fits the data, and turning the result into something a committee will act on.

CHDA Exam Study Guide is a focused, fully offline companion for AHIMA's Certified Health Data Analyst exam, organized exactly like the official exam content outline: all six domains, at the weights the exam gives them.

SIX WAYS TO STUDY
• Flashcards — tap to reveal, tagged by domain
• Multiple-choice questions set in real analyst scenarios — a readmission rate that moves when the denominator changes, a query returning duplicate encounters after a join, a dashboard that hides a coding backlog — each with a worked explanation
• True/false drills built from the misconceptions that cost marks
• Term-matching game — pair key terms in rounds of five
• Searchable glossary of the data, statistics, coding and governance vocabulary the exam assumes you know
• Formulas reference — rates, ratios and proportions, case-mix index, length-of-stay and readmission measures, risk adjustment, sensitivity and specificity, sampling and confidence intervals, each with the trap to avoid

ALL SIX DOMAINS, EXAM-WEIGHTED
• Foundational Knowledge of Analytics in Healthcare (14–16%) — the data landscape, terminologies and code sets, reimbursement methodologies, privacy and security
• Business Needs Assessment (11–15%) — turning a stakeholder request into an answerable question, scope, requirements and feasibility
• Data Acquisition (14–18%) — source systems, EHR and claims data, queries and joins, data quality, validation and cleaning
• Data Analysis (22–25%) — descriptive and inferential statistics, comparisons, trending, risk adjustment and benchmarking
• Data Interpretation & Reporting (18–22%) — visualization choices, dashboards, narrative, and reporting to clinical and executive audiences
• Data Governance (8–10%) — stewardship, master data management, metadata, retention, integrity and regulatory obligations
