When the time comes to write a resume / CV, you may think from the perspective, naturally so, of the job you want, the salary you want, and perhaps other considerations such as where you want to live.
However, in order to write a resume / CV that works, you need to change your perspective. A resume that works is one that clearly, strongly, and simply communicates to the employer what HE wants. Tips for the perfect administrative assistant resume, first of all you need ask yourself: 
What skills do you have to solve his problems?
How is your experience going to help his business?
What expertise will you contribute to his organization?
Your resume / CV needs to begin with a section on what you bring to the table. This is a 180-degree turn from the traditional objective. Too many clients begin with "Objective: A challenging position that provides the opportunity for advancement…" That statement is all about what you want. Instead, offer the employer your assets and expertise.
Not incidentally, your assets and expertise are above and beyond things like "good communication skills" and "attention to detail." Just think: EVERYONE can make points like that on a resume. And if everyone can say these things, then by you saying them, you're not making yourself stand out from the crowd. Instead, focus on the assets that you and you alone possess.
In the experience section of your resume / CV, avoid the tendency to provide your job description. In most cases, your mere job title adequately conveys what you do from 9-5. Instead, present what you do in the job that constitutes an achievement, accomplishment, or success. Points such as these go above and beyond the job description, so that the resume / CV is no longer about your job, but about YOU.
The education section of your resume / CV is an important consideration, and unfortunately it's a section that many people fail to present well. The key to an effective education section is placement. Should it be placed near the top of the resume or the bottom? The way to evaluate this is to consider whether your education is recent, related to your intended job / career, or in some way exceptional. Think about your specific situation, because there is no hard and fast rule saying your education must be at the beginning of the resume / CV, or at the end.
In summary, writing a resume / CV that works means writing a resume / CV that is not you-centered, but rather, employer-centered. Tell the employer what he wants to know, and what he wants to know is how you will benefit him.
