An administrative assistant typically supports people or teams with scheduling, documents, records, communication, and coordination. An office manager may take broader responsibility for office services and operations, including staff, procedures, supplies, or facilities. Because employers use “office manager” for jobs with different levels of authority, compare the actual duties and decision-making scope—not just the title.
How the roles differ
The clearest distinction is the work’s scope. Administrative assistants usually keep day-to-day work organized for an executive, team, or department. Office managers may coordinate or direct the services that keep an office running. The second role can involve more operational ownership, but that is not guaranteed by the title.
| Area | Administrative assistant | Office manager or related management work |
|---|---|---|
| Main focus | Schedules, documents, records, calls, and coordination for people or teams. | Office services and operations; duties may include staff, processes, supplies, records, or facilities. |
| Typical decisions | Organizes and prioritizes support work. Executive assistants may take on complex support and research. | May set goals and deadlines, supervise staff, and recommend changes to policies or procedures. |
| Common skill areas | Organization, communication, writing, judgment, office procedures, records, and software. | Leadership, analysis, communication, attention to detail, and operational coordination; facilities or compliance knowledge when those duties apply. |
| Typical preparation | Entry-level roles commonly accept high school graduates comfortable with word processing and spreadsheets; procedures are often learned on the job. | For administrative services managers, a bachelor’s degree and related work experience are typical, though requirements vary. |
The U.S. Bureau of Labor Statistics (BLS) describes secretaries and administrative assistants as doing routine clerical and organizational tasks, including arranging files, preparing documents, scheduling appointments, supporting staff, answering calls, handling mail, and maintaining databases. Some also do basic bookkeeping or buy supplies. Duties vary with experience, specialty, and employer. BLS: Secretaries and Administrative Assistants
By contrast, the BLS’s administrative services manager profile covers broader work such as supervising staff, setting goals and deadlines, changing procedures, and overseeing office support services. Depending on the organization, the work may also include facilities, maintenance, safety, security, or regulatory compliance. In a small organization, the BLS says these managers may direct all support services and be called business office managers. That comparison helps explain the possible scope of an office manager job; it does not mean every office manager has those responsibilities. BLS: Administrative Services and Facilities Managers

Skills and qualifications to expect
Administrative assistant roles
The BLS highlights decision-making, interpersonal, organizational, and writing skills. Comfort with word-processing and spreadsheet programs is useful for entry-level work; many workers learn an employer’s procedures over a few weeks on the job. Legal and medical administrative roles may require additional terminology training, while executive administrative assistants typically have several years of related experience. A bachelor’s degree is generally not required, although some employers may prefer postsecondary study for executive support positions. BLS: Secretaries and Administrative Assistants
O*NET’s administrative assistant profile includes knowledge of office procedures, file and record management, word processing, English, computer applications, and customer service. Treat these as useful skill areas rather than a checklist that applies to every vacancy. O*NET: Secretaries and Administrative Assistants
Office management and administrative services management
For administrative services managers, the BLS says a bachelor’s degree and related work experience are typical, but requirements differ by organization and duties; some people enter with a high school diploma. Related experience should show managerial or leadership ability. Analytical thinking, communication, attention to detail, and leadership are useful, with facilities or compliance knowledge relevant when those areas are part of the job. BLS: Administrative Services and Facilities Managers
These are general occupational patterns, not minimum requirements for every job titled “office manager.” Read each posting for the employer’s actual expectations, such as staff supervision, purchasing authority, budget responsibility, or facilities oversight.

Administrative experience can be a foundation for broader office operations responsibility, but there is no universal promotion ladder. The BLS notes that executive secretaries and executive administrative assistants typically have several years of experience in other administrative positions. Moving toward management is a reasonable direction for someone who builds relevant experience and demonstrates leadership, but each employer sets its own requirements.
To prepare for roles with broader operational scope, look for opportunities to develop evidence of:
- Owning or improving a recurring process.
- Coordinating work across teams or with vendors.
- Tracking purchasing, supplies, records, or budgets where the role allows.
- Training or supervising colleagues.
- Taking responsibility for facilities, safety, or compliance tasks when relevant to the organization.
These experiences align with duties in the BLS’s administrative services manager profile, but they are practical ways to demonstrate readiness—not formal requirements for every office manager vacancy. BLS: Administrative Services and Facilities Managers
Pay and job outlook: read the categories carefully
Federal wage and employment figures offer context, not a direct salary comparison between the two job titles. “Office manager” can describe jobs with widely different responsibilities, and the available BLS categories differ in both scope and reference year.

Use the responsibilities and authority in each posting to identify the real difference between the jobs:
- Who receives the support? Is the work mainly for an executive, team, or department, or does it serve the office as a whole?
- What can the employee decide? Does the role organize assigned tasks, or can it set procedures, deadlines, or priorities for others?
- Is there staff responsibility? Look for training, scheduling, performance oversight, or direct supervision.
- Which operations are owned? Check for purchasing, vendors, supplies, records, budgets, facilities, safety, or compliance.
- What experience is required? Distinguish software and office-procedure skills from demonstrated leadership or operational experience.
A job called “office manager” may primarily provide administrative support, while another may direct multiple office functions. The duties, authority, and qualifications in the posting give a more reliable basis for comparison than the title by itself.
