Internal promotion cover letter for an existing employee

Applying for a role above your current one inside your own company is its own thing. The reader already knows you, so the letter has to show readiness, not introduce you. Give it your current role, time served, your achievements and the evidence you are ready, and it writes a letter that builds the case for the step up without rehashing your whole history.

Write me a cover letter for an internal promotion application.

Role I am applying for: {TARGET_ROLE}
My current role: {CURRENT_ROLE}
Company: {COMPANY_NAME}

Key achievements in this company: {KEY_ACHIEVEMENTS}
Why I am ready for this step up: {READINESS_EVIDENCE}
Name of hiring manager (if known): {HIRING_MANAGER_NAME}

Constraints:
- Maximum {WORD_LIMIT} words
- Leverage insider knowledge of the company's goals and culture without being sycophantic
- Reference specific internal projects or results with measurable outcomes
- Address what I will do differently or additionally in the new role compared to my current one
- Tone should be confident and collegial, not overly formal
- Do not simply list my job description; focus on impact
