One of my favorite topics in Psychology is personality and there happens to be a very good Five Factor test that is free to the public domain with all 3,000+ items available for download. Some notes about the IPIP NEO-PI:

Purpose of this On-Line Inventory

• The primary purpose of this on line inventory is to educate the public about the five factor model of personality.
• More specifically, the report explains the likely consequences of one's standing on five broad personality domains.
• These broad domains cover normal differences in personality that should be obvious to people who know you well.
• Secondarily, this inventory estimates your standing on the 5 broad domains and 30 subdomains of personality.
• The inventory does not reveal hidden, secret information about you nor does it assess serious psychological disorders.
• The report is designed to be objective, not pleasing or flattering.
• Measurement error, misunderstandings, carelessness, and mischievous responding can invalidate the report.
• If knowledgeable acquaintances disagree with the test results, then the results are wrong.
