Ranking and Rating Methodology

Respondents to the Vault.com survey rated accounting firms on these seven dimensions or attributes (the percentage weights in parentheses are applied to derive the overall ranking):

  1. Prestige (40%)
  2. Firm culture (20%)
  3. Work-life balance (10%)
  4. Compensation (10%)
  5. Overall job satisfaction (10%)
  6. Business outlook (5%)
  7. Formal training programs (5%)

Additional Criteria

Though they do not factor into the overall ratings, Vault.com also includes these evaluation criteria in its surveys:

  • Benefits
  • Client Interaction
  • Green Initiatives
  • Firm Leadership
  • Hiring Process
  • Hours
  • Informal Training
  • Internal Mobility
  • Philanthropy
  • Promotion Policy
  • Relations With Supervisors
  • Travel Requirements

Also measured is diversity along each of these dimensions:

  • Overall
  • For Women
  • For Minorities
  • LGBT
  • For People With Disabilities
  • For Military Veterans

Limitations of the Rankings

While the rating and ranking methodology used by Vault.com is highly detailed, it nonetheless represents a summary of the personal opinions of survey respondents. As a result, it is fundamentally highly subjective.

Accordingly, these rankings may or not be representative of your own preferences in choosing among employers, work situations, and career paths. Another open question is how closely the pool of survey respondents actually represents the opinions of all employees.

Although the Big Four fill the top 4 spots overall, they regularly score much lower (usually in 20th place or below) along the dimensions that are most indicative of their desirability as places to work, most notably firm culture, work-life balance and job satisfaction. Being the top 4 in prestige, which gets the highest weight, accounts for their high placement overall. This suggests that the Big Four may be more desirable as resume-building stopovers in a career path pointed elsewhere than as long-term career destinations.

In the 2013 survey, BDO and McGladrey ranked 29th and 28th overall, respectively.

By the next year, both had entered into the top 10, where they have remained since. Such a dramatic move raises questions about the robustness and quality of the survey samples.
