How is a motivation letter different from a statement of purpose for my PhD application?

The two documents overlap, but they lean in different directions. A motivation letter centres on why you want this doctoral programme, while a statement of purpose usually covers a wider picture of your background and goals. The distinction is not consistent across universities, and some treat them as the same thing.

Motivation Letter vs Statement of Purpose

Tips That Apply to Both

• Check how the university describes the document, since the terms are sometimes used interchangeably.
• Tailor each application by referring to specific faculty members, research groups or facilities.
• Use sample letters only as a guide to structure and tone, not as text to reuse.
• Avoid repeating your CV, generic statements and unrelated personal stories.

My Advice

Read the university's instructions word by word and answer exactly what they ask. If the prompt is unclear, write to the department and ask what they expect rather than guessing.
