How IQNIVA scoring works

Transparency builds trust. Here’s what our IQ-style score means and how we compute it.

Important: IQNIVA provides an IQ-style estimate (mean 100, SD 15) for fun and training. It is not a clinical assessment.

What we measure

Our tests focus on reasoning task families commonly associated with “fluid” style reasoning: pattern detection, sequences, spatial rotation, and basic logic.

How the IQ-style number is computed (v1)

  1. Each question has a difficulty (1–5). Higher difficulty has a slightly higher weight.
  2. Your score is based on weighted accuracy across the questions you answered.
  3. We convert weighted accuracy to a z-score using a reference band (mean ~0.60, SD ~0.15), then map it to an IQ-style scale: IQ = 100 + 15·z.
  4. Percentile is derived from a normal model for interpretability.

As we expand, we can improve calibration using larger anonymous aggregates (if enabled) or better difficulty modeling. This build ships with a clear, consistent baseline.

Why weekly retesting

Daily retesting is noisy. Weekly retesting lets you see real improvement from practice and explanation review.
