What Is a Job Covering Letter?

A job covering letter is a one-page document sent alongside your resume when applying for a job. Its purpose is to introduce yourself, explain your interest in the position, and highlight key qualifications relevant to the role. Unlike a resume, which is factual and structured, a cover letter is more personalized and persuasive.

Why It Matters

• Provides context to your resume
• Showcases communication skills
• Highlights your personality and motivation
• Helps you stand out among applicants

When to Use a Cover Letter

You should include a cover letter in almost every job application unless explicitly instructed otherwise. It is especially important when applying for roles such as administrative positions (see this office administrator cover letter PDF example) or specialized roles like admissions (check this admissions representative cover letter guide).

Structure of a Perfect Cover Letter

A well-structured cover letter ensures clarity and professionalism. Here is the ideal format:

Key Elements Explained

• Header: Include your name, email, phone number
• Greeting: Use “Dear Hiring Manager” if unsure
• Introduction: Grab attention immediately
• Body: Use measurable achievements
• Closing: Request an interview
