Are they really important and do employers really read them? The answer to both of these questions is a resounding YES! Cover letters are an extremely valuable vehicle for demonstrating in greater detail the individual skills and qualifications outlined in your resume.
Composing a well-written and effective cover letter can be tricky. However, with a little time, effort, style, and creativity, you can separate yourself from the competition. A cover letter creates a window of opportunity in which you can highlight your specific skills, background, and experiences that are related to the employers' wants and needs.
Format
The style and appearance of a cover letter is important. There are many formats of cover letters, but the majority of cover letters follow a formal business letter format which is the full-block format. In this style, all parts of the letter, including the first lines of paragraphs, are flush with the left margin. Quality bond paper matching your resume paper gives the most professional appearance.
Content
Target your letter to the desired position, use concise statements, and focus on the employer's needs and requirements. When possible use percentages, numbers, or dollar amounts to measure achievements and results. The Career Management Center maintains sample job descriptions and offers individual cover letter reviews to assist with the preparation of your cover letter.
