Quizgrid

Assessments and proctored exams with auditable integrity for cert programs

Quizgrid is an assessment and proctoring platform for organizations that issue certifications, license exams, or any credential where someone might be tempted to cheat. It runs on the Internal Tools Stack because the buyer is usually a compliance head as much as a product head — audit logs, immutable evidence retention, and chain-of-custody on every test session are non-negotiable.

Key features

  • Question bank with item types (MC, multi-select, short-answer, code, freeform)
  • Test authoring with sections, time limits, and randomized item selection
  • Live proctoring (camera + screen + audio) with optional AI-assist flagging
  • Self-proctored mode with browser lockdown and tab-detection alerts
  • Item analysis (difficulty, discrimination, distractor performance)
  • Score reports with pass / fail letter and per-section breakdown
  • Retake policies with cooldown, max-attempts, and version-rotation rules
  • Immutable session evidence retention (recordings, screen captures) for audit

What you get

Quizgrid lands as a multi-tenant SaaS under your brand. The first item bank is imported from CSV or QTI XML; proctor pools are configured if live proctoring is in scope; the first parallel-run exam validates score reports against the customer’s historical baseline.

Sample customer story (placeholder — illustrative only)

A national professional-licensing body for a regulated trade licensed Quizgrid to consolidate twelve separate vendor tools they had been using across exam delivery, proctoring, and certificate issuance. The win was the audit log: their first regulator-requested evidence pull (chain of custody on a contested score) returned a complete bundle in under an hour instead of the prior two-week scramble.

What’s NOT included

  • K-12 classroom assessments. Quizgrid is for high-stakes / certification-grade testing. Classroom formative assessments are a different fit.
  • Item bank authoring at scale (psychometric IRT pipelines). We support item analysis and IRT scoring; full IRT calibration pipelines are an integration with partner psychometric tools.
  • Live human-watcher proctor sourcing. We provide the proctor console; staffing live proctors is the customer’s responsibility.
  • AI-only auto-proctoring without a human reviewer. Quizgrid AI flags incidents; final adjudication is always a human decision by design.
