What is the difference between Background Investigation vs Background Check?
| Aspect | Background Investigation | Background Check |
|---|---|---|
| Purpose | In-depth assessment of an individual's history and character | Basic verification of criminal, employment, and educational records |
| Scope | Comprehensive, including interviews and detailed research | Limited, often automated or document-based |
| Credentials | May require specialized training or certifications | Minimal, often performed by HR or screening services |
| Work Environment | Private investigation firms, security agencies | HR departments, online screening services |
While both involve reviewing an individual's history, a Background Investigation is more detailed and thorough, often used for sensitive positions.
