Are there any question bank systems that support randomization and secure item reuse across assessments?

Yes. Many assessment platforms support question banks/item banks with both randomization and secure item reuse across multiple assessments.

Common capabilities to look for

• Randomized item selection from a pool
• Multiple forms / equivalent test versions
• Item tagging / metadata for topic, difficulty, learning objective
• Exposure controls like item use limits, rotation, or locking
• Secure reuse with permissions, encryption, or audit logs
• Delivery controls such as shuffling answers, timing, and browser lockdown
• Analytics to monitor item performance and detect overexposure

Examples of systems that often support this

• Canvas Quiz/Item Banks
• Moodle Question Bank
• Blackboard Test Pools
• D2L Brightspace Question Libraries
• Respondus / LockDown Browser + Test Banks
• ExamSoft
• Questionmark
• Mettl / Mercer | Mettl
• TAO Testing Platform
• Inspera Assessment
• Xamk / other custom LMS assessment modules depending on configuration

Important note on “secure item reuse”

If by “secure” you mean protecting items from leaking or overexposure, the strongest systems usually include:

• role-based access control
• versioning and audit trails
• item encryption or secure storage
• randomized subsets per candidate
• item rotation and statistical exposure management

If you want, I can also help you compare these by:

1. open-source vs commercial,
2. best for schools vs certification exams, or
3. features like psychometrics, blueprinting, and item security.
