An audit career in a public accounting firm is a ladder with a fixed shape and flexible timing. The shape is the same almost everywhere: you start by performing procedures, move to supervising people who perform them, then to managing the engagement, and finally to owning the client relationship and the report. The titles and the pace differ by firm, and no firm's published materials promise a standard schedule.
This guide describes each level as firms and the auditing standards describe it, shows what changes in the job at each step, and explains where licensure and other credentials fit. It is written for people deciding whether to start in audit, for staff weighing the next step, and for firm leaders who want to explain the ladder to new hires.
The ladder at a glance
Most US firms use some version of these levels. Names vary: staff may be called associate or assistant, and many firms add sub-levels (senior associate II, manager I) or a director level between senior manager and partner.
| Level | Core job | What the firm needs from you |
|---|---|---|
| Staff (associate) | Perform procedures and document them | Accurate, complete workpapers on time |
| Senior (in-charge) | Run fieldwork, supervise staff, first-level review | A team that finishes on budget with clean files |
| Manager | Plan the engagement, review the work, manage the client | Sound judgments on risk and a client who is kept informed |
| Senior manager (director at some firms) | Oversee several engagements, staffing and budgets | Engagements delivered across a portfolio, with growth |
| Partner (principal) | Own the engagement, the report and the relationship | Quality, risk management and new work |
The glossary entry on audit firm roles gives the review layering in short form, and the financial statement audit process shows where each level's work sits in an engagement.
Staff: learning the work by doing it
Deloitte's US campus recruiting page describes what early-career audit staff do: understand the client's business, assess risks, and evaluate financial statements, transactions, disclosures and internal controls, using analytics tools to find patterns and anomalies, and testing internal control processes as part of a team. That matches the daily work at any firm. A staff auditor is handed a section of the audit, such as cash, payables or fixed assets, and is expected to:
- request and obtain support from the client
- perform the tests the audit program sets out, such as vouching, confirmations and recalculations
- document the work so another person can follow it (see audit working papers and tick marks)
- raise exceptions to the senior early, with the facts
Licensure usually starts here. Deloitte's page states that financial statement audit candidates must meet the minimum educational requirements for CPA licensure in the state of their office before starting full-time, and that those requirements may differ from the requirements to sit for the exam. BLS reports that all states require 150 semester hours of college coursework for CPA licensure, about 30 more than a typical bachelor's degree. See the 150-hour rule and the CPA Exam entries. Because boards set the details (start at the state hub), check your own state board's rules for exam eligibility, license requirements and experience before you plan your first two years.
Senior: from doing to directing
The first promotion changes the job more than any other. A Deloitte US senior-level posting describes the role as supervising assigned staff and giving a first-level review of their work, across a variety of industries and business models. In practice a senior:
- leads fieldwork on site or remotely, and assigns sections to staff
- plans the day-to-day schedule against the budget
- reviews staff workpapers and writes review notes
- performs the more judgmental areas, such as estimates, revenue and journal entry testing
- is the client's main contact for requests and status during fieldwork
The common obstacles at this level are time budgets (see realization and utilization) and busy season, covered for small firms in managing busy season.
Manager: owning the engagement plan and the review
Deloitte's published description of its manager level (from its Australian careers site, so a general guide to the firm's structure and not a US job spec) says managers lead project teams, coach team members, oversee delivery from planning through completion, manage client relationships and contribute to business development. For an audit this translates into:
- Planning. The manager shapes the audit planning memo: risk assessment under AU-C 315, materiality, the staffing plan and the timeline.
- Review. The manager reviews the seniors' work and the whole file for sufficiency and appropriateness of evidence, and decides what additional work is needed.
- Client communication. The manager runs status meetings, discusses proposed adjustments and drafts the management letter.
- Accounting judgment. Technical questions come here first, and the manager decides which ones go to the partner or to the firm's consultation process.
Workpaper documentation under AU-C 230 must show who performed and who reviewed the work, so the manager's sign-off is part of the permanent record. The manager is also where many firms start to evaluate people for growth: staff reviews, coaching and fixing problems before the partner sees them.
Senior manager and director: running a portfolio
Deloitte's description of the senior manager stage is leading larger, more complex projects and major client relationships and acting as a trusted advisor. In an audit practice this usually means several engagements at once, with managers reporting to you, and the following added duties:
- staffing across engagements and resolving conflicts in the busy season
- dealing with difficult accounting or auditing issues before they reach the partner
- managing budgets and realization for a group of clients
- proposing additional services the client needs, within the independence rules (see independence and nonattest services)
- supporting the partner in proposals and in the firm's peer review and inspection preparation
Some firms use a director title for this tier. Deloitte describes the director or managing director level as accountability for a business area's performance and large client engagements.
Partner: responsibility for the report
Deloitte describes partners as driving firm-wide strategy, revenue growth and talent development while sustaining key client relationships. For an audit partner, the professional standards add something specific. Under AU-C 220, the engagement partner is ultimately responsible and accountable for compliance with the engagement-level quality requirements and for the report issued on the firm's behalf. Some tasks the partner must perform personally, while others the partner may assign to qualified team members but remains accountable for. See AU-C 220 and SQMS 1.
A partner's week looks different from a manager's:
- reviewing significant risks, key estimates and the draft report
- deciding on the audit opinion, including modified opinions
- handling client acceptance and continuance, and fee discussions
- communicating with those charged with governance
- selling new work, developing future leaders and managing the firm's risk
Partnership rules differ by firm and by state. Who may own a firm, whether a license is needed to be a partner, and how equity is shared are set by state accountancy law and by the firm's own agreement. Ask a firm for its criteria in writing before you plan around them.
How long does each step take?
There is no standard. The firm pages read for this guide give responsibilities but no US promotion schedule. One published example is EY Switzerland's careers FAQ, which describes about two to three years as staff and another two to three years as senior auditor before the manager, senior manager and director or partner stages. That is a non-US firm and it does not generalize to US practice. In US firms, timing depends on the licensure date, performance, engagement mix, staffing needs and the number of partner openings, so ask for the firm's promotion criteria and for how recent cohorts have moved.
What does BLS say about the occupation?
BLS groups accountants and auditors together. Its Occupational Outlook Handbook reports a median annual wage of $83,680 in May 2025, projected employment growth of 5 percent from 2025 to 2035, faster than the average for all occupations, and about 115,300 openings each year, mostly from replacing workers who leave the occupation. Those figures cover the whole occupation, including accountants in industry and government, and do not describe any level of a public accounting firm. BLS also notes that longer hours are typical during periods such as quarterly audits or tax season. It reports that entry-level public accountants may advance to senior positions as they gain experience and take on more responsibility.
Credentials beyond the CPA
The CPA license is the main credential for a public accounting career, because a license is generally needed to sign an attest report. Others add specialization:
- CFE for fraud examination (see the CFE exam guide)
- CIA for internal audit and CISA for information systems audit, useful if you move toward IT audit or internal audit
- Government audit competence, which carries its own CPE requirement for auditors on Yellow Book engagements
CPAs also have to keep their license current with continuing professional education. See free CPE for CPAs for what counts.
Exits from the ladder
Many people leave the partner track and move into careers their audit experience prepared them for. BLS says management accountants often start as cost accountants, junior internal auditors or trainees and may move up to accounting manager, budget director, controller or chief financial officer roles. Common destinations include corporate accounting and financial reporting, internal audit, forensic accounting, government and nonprofit finance, and other service lines in the same firm.
Moving after two or three years at a firm is common and is an ordinary outcome of the ladder, not a failure of it.
Frequently asked questions
How long does it take to make partner in public accounting?
No firm source read for this guide gives a standard US number. The time depends on the firm, the partner openings and your performance. Ask any firm you are considering how it defines the criteria and how recent promotion classes have moved.
What does an audit senior do?
A senior supervises staff, gives first-level review of their workpapers, runs fieldwork and takes on the more judgmental audit areas. The senior also works as the client's day-to-day contact during fieldwork.
Do you need a CPA license to work in audit?
You can work as audit staff before you are licensed, and firms generally hire candidates who are on the way to licensure. A license is generally needed to sign an audit report, so the partners who sign must be licensed. Deloitte's US campus page says CPA licensure is not required for some Audit & Assurance roles but is a preferred skill; for its financial statement audit roles, candidates must meet their state's minimum education for licensure first. Firms set their own timing for the license in promotion decisions. Rules differ by state, so check your state board for exam and license requirements.
What is the difference between an audit manager and a partner?
The manager plans and reviews the engagement for the partner. The partner is accountable for the engagement and the report and carries the firm's risk and client relationship. Under AU-C 220 the engagement partner is ultimately responsible for the quality of the engagement.
Is audit a good start for an accounting career?
BLS reports faster-than-average growth for accountants and auditors from 2025 to 2035, and lists inspecting accounting systems and identifying fraud risks among the occupation's duties. Audit training transfers to industry, internal audit and forensic work, and many people use it that way.
CORAA prepares audit files for US CPA firms from QuickBooks books. The firm's own people perform the audit and sign the report.
