Who it's for

• Complete a project or capstone that you can point to in future applications.

How to apply well

Selection is competitive but not unrealistic. A thoughtful application usually beats a decorated one.

• Start with the deadline: July. Work backwards — most students underestimate how long recommendations and essay drafts take.
• Read the official page twice before writing anything. Note the exact prompts and word counts.
• Answer the actual question. Reviewers read hundreds of essays; specificity beats polish.
• Submit at least 24 hours before the deadline. Portals crash. Files fail to upload. Give yourself the buffer.

Cost, funding & logistics

Cost and logistics kill more applications than eligibility does. Sort these out before you get emotionally invested.

• Format: In person in Leiden, Netherlands.
• Duration: 1-3 weeks.

After the program

The most valuable thing you leave Leiden University Summer Schools with is usually not the credential — it's the two or three people you met and the one concrete thing you made.
