The EA-to-Chief-of-Staff Path: How to Make the Leap
Takeaway: The move from executive assistant to Chief of Staff is less about learning new software and more about shifting from executing decisions to shaping them, and the best way to make it is to start operating like a Chief of Staff before you carry the title.
Plenty of executive assistants are already doing a version of the Chief of Staff job. They run the calendar that runs the company, they see every fire before it spreads, and they know how the principal actually makes decisions. What separates the two roles isn't access. It's scope, mandate, and the kind of judgment you're trusted to apply.
This guide walks through what actually changes in the leap, how to know if you're ready, and the specific steps that move you from support to strategy.

What actually changes between EA and Chief of Staff
An executive assistant role is largely tactical. You manage the principal's time, communications, travel, and the flow of information into and out of their office. You keep a complex life running. Done well, it's skilled, high-trust work.
The Chief of Staff role is largely strategic. In his Harvard Business Review case for the position, longtime CEO adviser Dan Ciampa describes the Chief of Staff as an "air traffic controller" for the leader and the senior team, an "integrator" who connects work streams that would otherwise stay siloed, and an "honest broker" who can give the leader a wide view without turf considerations (Harvard Business Review).
Put plainly, the EA keeps the principal's day working. The Chief of Staff keeps the principal's priorities working across the whole organization. You move from managing tasks to managing outcomes, from scheduling meetings to deciding which meetings should exist at all, and from carrying decisions to helping form them.
The mindset shift is the real leap
Most of the practical skills carry over. The calendar discipline, the discretion, the ability to anticipate needs, the relationships across every department. What has to change is how you think.
As an EA, your default question is often "how do I get this done." As a Chief of Staff, the question becomes "should this be done, and is it the highest-value use of the principal's attention right now." You start saying no on the principal's behalf. You start owning problems rather than routing them. That's uncomfortable at first, and it's exactly the muscle hiring managers are testing for.
Is the leap right for you (and does it pay)?
Before you chase the title, be clear on why. The Chief of Staff role isn't automatically a promotion in pay. Compensation depends on the organization, the industry, and how the role is scoped. A senior executive assistant at a large, well-funded company can out-earn a Chief of Staff at an early-stage startup.
For context, the U.S. Bureau of Labor Statistics reported a median annual wage of $70,310 for executive secretaries and executive administrative assistants in its May 2023 wage data (BLS OEWS). Chief of Staff compensation varies far more widely and isn't tracked as a single BLS occupation, so treat any single "average" number with caution and evaluate each offer on its own terms.
Good reasons to make the move include a genuine pull toward strategy and operations, a desire to own cross-functional problems, and a career goal that runs through general management or operations leadership. A weaker reason is simply wanting a more impressive title. The work is broader, more ambiguous, and more exposed. Make sure you want that, not just the label.
Five steps to make the leap
1. Start doing the job before you have the title
The most reliable path is to expand your current role until the Chief of Staff title simply formalizes what you already do. Volunteer to own a recurring problem that sits between departments. Take the messy cross-functional project nobody wants to coordinate. Start preparing the principal for meetings with a short brief rather than just a calendar entry.
Every one of those moves builds evidence. When the conversation about a new role happens, you want to point to results, not potential.
2. Build business fluency
Ciampa lists "business savvy" among the foundational abilities an effective Chief of Staff needs, alongside project management, communication, and a feel for the pressure points facing the leader (Harvard Business Review). If you have spent your career in support, this is often the biggest gap to close.
Learn how your company actually makes money. Read the board deck, or ask to. Understand the operating metrics leadership watches, the budget cycle, and how decisions get funded. You don't need an MBA. You need to be able to sit in a leadership conversation and follow the substance, not just the logistics.
3. Widen your relationships
As an EA, your primary relationship is with the principal. A Chief of Staff needs credibility across the entire leadership team, because much of the job is influence without direct authority. Start building those relationships now. Understand what each department head is trying to accomplish and where they get stuck. When you eventually operate across the organization, trust is the currency you will spend, and you can't build it overnight.
4. Make the business case, in writing
If the role doesn't exist yet at your company, propose it. Write a short document that names the problems a Chief of Staff would solve for the principal, defines the scope, and sets clear expectations at 30, 60, and 90 days. Show where the role sits on the org chart and how it differs from your current one. Leaders respond to a clear, well-reasoned proposal far better than to a general request for a promotion.
If the role does exist elsewhere, treat the internal transition as a real interview. Prepare as if you were an external candidate.
5. Close specific skill gaps deliberately
Look at Chief of Staff job descriptions in your industry and note the recurring requirements: strategic planning, project and program management, data literacy, financial acumen, executive communication. Compare them honestly against your experience and pick the two or three real gaps. Then close them through stretch assignments, a targeted course, or mentorship from a current Chief of Staff. Deliberate, visible skill-building beats a general "I'm ready" every time.
If you want a structured way into the role, a focused certification can shorten the ramp and give you language for interviews. Nova Chief of Staff is the most established option, and Brief readers get $100 off (see the Nova course).
Common mistakes to avoid
- Waiting to be chosen. The role rarely comes to you. Operators who make the leap tend to create the opening.
- Dropping the support instincts that made you good. Discretion, anticipation, and reliability still matter enormously. You're adding judgment, not discarding service.
- Overpromising on strategy while underdelivering on execution. Early credibility usually comes from getting hard, cross-functional things done, not from having opinions in meetings.
- Assuming the title equals a raise. Negotiate the role and the compensation as separate, explicit conversations.
Frequently asked questions
Do I need a degree or an MBA to become a Chief of Staff? No. Many Chiefs of Staff come from operations, consulting, or executive support without an advanced degree. Demonstrated judgment, business fluency, and a track record of getting cross-functional work done matter more than a specific credential.
How long does the transition usually take? It varies widely. When you expand your current role and formalize it internally, the shift can take months. When you're moving to a new company, expect a longer search, since Chief of Staff roles are competitive and often filled through networks.
Will I take a pay cut moving from a senior EA role to Chief of Staff? Possibly, depending on the employer. A Chief of Staff at a small or early-stage company may earn less than a senior EA at a large enterprise. Evaluate the total package and the career trajectory, not just the base salary.
What is the single most important skill to develop first? Business fluency. The ability to understand and speak to the substance of the business, not just the logistics around it, is what turns a strong assistant into a credible Chief of Staff.
How do I go from executive assistant to chief of staff? The most reliable path is to operate like a Chief of Staff before you hold the title. Take on a cross-functional problem that sits between departments, build fluency in how the business makes money, and widen your relationships across the leadership team. Then make the case in writing, defining the role's scope and early milestones. Dan Ciampa's account of the role stresses business savvy and project management as foundational (Harvard Business Review). Formalize what you already do rather than waiting to be chosen.
