Test Security and Fairness
Test Security and Fairness
Test security protects the integrity of exam content and scores. Threats include item exposure, cheating, test compromise, and unauthorized access. Physical security (locked storage, secure servers) and procedural security (proctor training, ID verification, randomized seating) are essential. Item development security includes nondisclosure agreements and secure transmission. Fairness ensures all candidates have equal opportunity to demonstrate competence, regardless of background. Accessibility accommodations (e.g., extended time, screen readers) must be provided without altering the construct. Bias can arise from content, format, or administration; sensitivity review and DIF analysis help detect it. A common trap is confusing accommodations with modifications-accommodations do not change what is measured, while modifications do. Another trap is assuming security is only about cheating; it also includes protecting candidate data (privacy). Incident response plans for security breaches (e.g., lost exam forms) must include notification and remediation. Worked example: If a candidate is found with unauthorized materials, the proctor must follow a documented incident report procedure, not improvise. Rule of thumb: security and fairness are ongoing processes requiring regular audits, training, and updates to policies.
