Our Research & Review Process

Big4AccountingFirms.org helps accounting students and professionals make big decisions — which firm to target, which career path to pursue, and which CPA resources are worth it. Those decisions deserve real research, not guesswork. Here’s the six-step process behind everything we publish.


1

Pull Primary-Source Data

We start with authoritative sources — firm reports, AICPA and NASBA data, and Bureau of Labor Statistics figures — so our foundation is facts, not hearsay.


2

Test Tools & Courses Firsthand

When we review CPA review courses or career tools, we get hands-on and test them ourselves, evaluating the real product rather than its marketing.


3

Interview & Survey Professionals

We gather input from people inside the profession — from Big 4 associates to hiring managers — to ground our coverage in lived experience.


4

Verify Salary & Career Claims

We fact-check compensation ranges, promotion timelines, and career-path claims against multiple independent sources before publishing.


5

Editorial Fact-Check & Score

Every article and ranking passes an editorial review for accuracy, and resources we recommend are scored on a consistent, weighted rubric.


6

Review & Update Annually

Firms restructure, salaries shift, and courses change — so we revisit our coverage at least once a year to keep it accurate and useful.



Independent, fact checked, and never pay-to-play — that’s how we earn the trust of future accountants.
