The summary of your administrative assistant experience on your resume should communicate information about your past employers as well as the skills and responsibilities required to do your job well. Different job seekers have different resume styles, but as long as you make sure your resume is free of errors -- typographical or otherwise -- and neatly formatted, you'll put yourself ahead of the competition in the administrative assistant job market.
Include a statement of your objective at the top of your resume. Your resume objective should identify a few key skills and experiences that separate you from the crowd in two or three sentences, placed below your name and contact information block. A clear and concise objective statement can set you apart from other candidates if you are looking for an administrative assistant position. In your objective statement, communicate to prospective employers that you possess the skills and experience important to working as a successful administrative assistant -- good organization skills, solid prioritizing ability, ability to multitask, ability to address vague instructions, resourcefulness and the ability to work well in a group and as a self-directed employee are all good examples of your work ethic to stress in your objective.
Identify the name of your past employer or employers at the far left of your resume. Include the full name of the employer if there is sufficient space. If you need to run the name of your employer on two lines of text because of space concerns, place the second line of text directly underneath the first line. Bold or italicize the name of the companies and organizations that employed you as an administrative assistant.
Identify the time frame when you worked as an administrative assistant for the different employers on your resume, either on the same line as the employers' names or directly below. Use months and years -- your date of hire and last day are not necessary. Also identify the location of each of your past administrative assistant positions -- prospective employers will appreciate knowing whether you have worked in a rural or urban setting in the past.
List your major responsibilities at each of your administrative assistant positions underneath the employer name and time period. Use neutral or positive language, and write in the past tense. A list of your major administrative responsibilities might look like this: "Answered phones, managed the Executive Director's calendar, drafted correspondence for senior staff, supervised administrative interns and managed inventory and supplies for the office."
Identify any major projects, achievements or supervisory experiences you managed at your jobs as an administrative assistant as a separate bullet point or entry underneath the respective employer. If you handled a major aspect of the company's business -- such as responding to customer inquiries or reviewing and distributing grant applications -- highlight that experience to make your resume stand out from the crowd. Also identify any awards you received, even internal awards given to employees within the company for outstanding contribution. An administrative assistant who is comfortable taking on additional responsibility -- and who excels at doing so -- is a desirable employee at almost any company.
