Frequently Asked Questions

These FAQs are designed to provide a better understanding of the Best Places to Work rankings. If you have questions about the rankings that are not covered here or elsewhere on this website, please contact us.

Data Sources and Methodology

What is the data source used for the Best Places to Work rankings?

The majority of the data used to develop the rankings was collected by the Office of Personnel Management through its Federal Employee Viewpoint Survey.  Visit our methodology page for more information.

Visit OPM’s website to learn more about the FEVS methodology.


How are your Best Places to Work rankings different from other rankings?

Our Best Places to Work rankings include only federal agencies, not private-sector or nonprofit employers as found in other workplace reports. The rankings are based on an extensive government-wide employee survey conducted by OPM, plus surveys from 12 additional agencies and the intelligence community. In addition, we rank agency subcomponents. We also provide extra information for every agency on 10 workplace categories that range from employee opinions on leadership to their perceptions of work–life balance.


What is the data source for the private-sector data?

Mercer | Sirota, our technical partner, supplies data that is used to create the private-sector Best Places to Work engagement score and provides employee responses to 28 questions that offer points of comparison with the federal government. The benchmarks from Mercer | Sirota are based on a normative database that is continually updated with client census survey data. Currently, more than one million survey responses from organizations in more than 100 countries are added to Mercer | Sirota’s database each year. This year’s benchmarks are comprised of nearly 4.7 million employee survey responses from more than 120 companies. Mercer | Sirota is the employee research and employee engagement business segment within Mercer, a global Human Resources consulting firm.


What is the source of the demographic data included in the agency profile?

The demographic data on the agency profile pages are from OPM’s FedScope database. The information is based on full-time, nonseasonal, permanent employees as of fiscal 2017, unless otherwise noted.


Why would an agency not have scores in some categories?

Several agencies do not take the Federal Employee Viewpoint Survey but participate in the rankings voluntarily. These agencies conduct employee surveys comparable to OPM’s survey and include our three employee engagement questions. The surveys may or may not include the questions required for each category. We have calculated category scores for these agencies where data is available. These agencies include: the Intelligence Community, Architect of the Capitol, Congressional Budget Office, Consumer Financial Protection Bureau, Department of Veterans Affairs, Federal Deposit Insurance Corporation, Government Accountability Office, Millennium Challenge Corporation, Office of the Inspector General at the Tennessee Valley Authority, Office of the Inspector General at the United States Postal Service, Peace Corps, Smithsonian Institution and the U.S. Army Audit Agency.

Who can participate in the Best Places to Work rankings?

Any agency with at least 100 federal employees is eligible to participate in the Best Places to Work rankings. Eligible agencies that do not participate in OPM’s government-wide annual employee survey can be part of the Best Places to Work rankings if they conduct a comparable survey that includes our three employee engagement questions. The survey needs to be administered during the same time frame as the Federal Employee Viewpoint Survey and have at least a 50 percent response rate. Please contact us to learn more about the survey requirements and how your agency can participate.


What is the definition of large, midsize and small in the agency rankings?

Agencies with 15,000 or more employees are included in the large agency category. Those with 1,000 to 14,999 employees are included in the midsize agency category. Agencies with more than 100 and fewer than 1,000 employees are included in the small agency category. Subcomponents—the subagencies, bureaus, divisions, centers and offices within agencies—need to have at least 100 employees to be included in the rankings. The number of employees was determined by using OPM’s FedScope database, at the end of fiscal year 2017, unless otherwise noted.


Why are agencies grouped by size?

We group agencies by workforce size to provide comparisons of organizations that may face similar management challenges in terms of numbers of employees and locations. The groupings have undergone several changes over the years. In 2003, the rankings featured only one list of agencies, including agencies as large as the Department of Defense (over 600,000 employees) and as small as the Office of Management and Budget (450 employees).


When will the next Best Places to Work rankings be released?

The next Best Places to Work rankings will be released shortly after OPM completes and releases its 2019 Federal Employee Viewpoint Survey.

Scores and Rankings

What does the Best Places to Work index measure and how is it calculated?

The overall rankings are based on the Best Places to Work index score, which measures employee engagement. For the purposes of our reporting, we are using the term employee engagement to refer to the satisfaction and commitment of the workforce and the willingness of employees to put forth discretionary effort to achieve results.

The measurement model for Best Places to Work was created in 2003 by our partner, CFI Group, which uses the same methodology for the highly regarded American Customer Satisfaction Index (ACSI).

The Best Places to Work index score is derived from three different questions in OPM’s Federal Employee Viewpoint Survey:

  • I recommend my organization as a good place to work.
  • Considering everything, how satisfied are you with your job?
  • Considering everything, how satisfied are you with your organization?

To calculate the score, we use the percentage of positive responses in a weighted formula. The more the question predicted intent to remain on the job, the higher the weighting. The weightings for the formula are proprietary.

The government-wide employee engagement score is calculated using data from agencies that participate in the FEVS. While agencies that conduct their own internal surveys, such as the Peace Corps, the Government Accountability Office and the Department of Veterans Affairs, are included in the rankings, their data is not used in the calculation of the government-wide employee engagement score. Visit our methodology page for more information.


How were the workplace categories determined and what survey questions does each include?

Our partner, CFI Group, created the measurement model for Best Places to Work in 2003. It used structural equation modeling to determine the clusters of questions included in each of the workplace categories: effective leadership; employee skills–mission match; pay; strategic management; teamwork; innovation; training and development; work–life balance; support for diversity; performance-based rewards and advancement.

The category scores are calculated by averaging the percentage of positive responses to the respective survey questions. Visit our methodology page or download our What the Categories Measure guide for a complete list of the federal survey questions included in each category.

How did you determine effective leadership was the key driver of the Best Places to Work index score?

We use regression analysis to determine which workplace categories were the best predictors of the Best Places to Work index score. Government-wide, the key driver is effective leadership, followed by employee skills–mission match and pay.


What are the definitions of “senior leader” and “supervisor”?

OPM’s Federal Employee Viewpoint Survey included the following definitions:

Senior Leaders: The heads of departments or agencies and their immediate leadership team responsible for directing the policies and priorities of the department or agency. May hold either a political or a career appointment and typically a member of the Senior Executive Service or equivalent.

Managers: Those in management positions who typically supervise one or more supervisors.

Supervisors: First-line supervisors who do not supervise other supervisors; typically those who are responsible for employees’ performance appraisals and leave approval.


Why aren’t past rankings shown?

We have different numbers of agencies participating in the rankings every year. For example, in 2007, 222 subcomponents participated in the rankings while 415 subcomponents were included in 2018. We also have made changes to the ranking’s categories. For these reasons, the rank is not the most accurate reflection of an agency’s performance over time. We recommend focusing on agency scores and quartile trends instead.

For Agencies

What can an agency do to improve its Best Places to Work scores?

There are many steps that agencies can take to improve employee engagement, and we offer a variety of resources, events and assistance for federal managers to better understand their data and build a tailored plan. To help leaders drive reforms, we work in partnership with agencies to conduct custom data analysis and lead them through a series of activities that identify and address employee concerns. We also have compiled case studies that examine federal agencies that have successfully used their Best Places to Work data to drive change. Please see our resources page for more details.

For Federal Job Seekers

I am trying to find a job in the federal government. Where do I go for more information?

USAJOBS.gov is the search engine and database for federal government jobs. All of the competitive jobs, those that are open to non-federal employee applicants, are listed there. Many agencies will also list job openings on their websites.

Visit our Go Government website to learn successful strategies for finding and applying for federal government jobs.

I was thinking about applying for a job at an agency that is ranked low. Should I reconsider?

Not necessarily. We hope that job seekers will use our Best Places to Work website as a resource, but there are many other factors to take into consideration when thinking about applying for a job.
