Many people who search out office assistant positions do not have higher education degrees and may have limited work experience, so writing an office assistant cover letter can be frustrating. The best way to start writing the letter is to read the job description carefully and determine which of your experiences and skills will show that you are the best candidate for the position. Highlight key words in the job description and use those words in your cover letter if possible. Remember to research the proper cover letter format, and proofread your office assistant cover letter several times before sending it out.
Start your office assistant cover letter by greeting the employer by name if possible. Be sure to note why you are interested in the position, and if you were referred by anyone within the company, be sure to note that in the first paragraph. You will want to keep the office assistant cover letter brief and to the point, so limit yourself to three paragraphs at most. In that first paragraph, after your greeting and other notes, be sure to note right away why you are the best candidate for the job. Cite a specific skill, experience, or level of education that will showcase your ability to be the best office assistant possible.
Briefly describe the skill or experience that fits best with the employer's needs. Go back and look at the highlighted words or phrases and determine which of your skills and experiences will most suit the employer's needs. Describe that skill or experience, but avoid too much detail; you will be able to expound on this item during an interview, and your resumé may feature even more information about the skill or experience. Give examples of past successes if possible, such as a time you were praised or otherwise recognized for your hard work.
If you have no previous experience as an office assistant, your office assistant cover letter will need to convey your skills that would suit you for the job. This can be tricky, but not impossible; note other jobs that may have been comparable in difficulty or even more difficult, and explain how those jobs prepare you for the office assistant position. Be confident and firm with your language, and avoid using phrases that will convey a lack of confidence or certainty. Tell the employer why you are the best candidate, not why you "think" you are the best candidate.
