Coming soonWhy most brain-score apps give you a number you can't use
They sell scores nobody can interpret, nobody can verify, and nobody tracks. The number lands, the novelty fades, and there's no reason to come back. We attacked that exact weakness.
Interpretable
Every score ships with a plain-language reading: what it means and what to do with it — not a bare digit.
Verifiable
An IBM Quantum-backed certificate you can check publicly. A credential you can show, not just a claim.
Current
Credentials carry a "current as of" date and a re-verification cadence. Your profile stays alive, not frozen in time.
One number. A meaning, a certificate, and a trend.
The Mirror Score is the interpretable, authority-stamped output the category doesn't offer. It reflects not just how you scored, but what the score means — and how it's moving.
- ✓ Plain-language interpretation
- ✓ Publicly checkable verification certificate
- ✓ Longitudinal trend you actually own
What a membership actually gives you
Not games. Not a number you forget by dinner. A working instrument for understanding — and proving — how your mind performs over time.
A score you can prove
Every verified result opens an immutable, IBM Quantum-backed certificate with a public check link. Show it to a school, an employer, or a skeptic — it stands on its own, not your say-so.
A number you can use
Each score arrives with a plain-language reading: what it means, where you sit, and exactly which domain to push — verbal, logic, numerical, or spatial — to move it.
Watch yourself change
Re-verification turns one data point into a trend line you own. See real movement across quarters instead of guessing from a test you took once, years ago.
Three lenses, one profile
Real World IQ (reasoning), Real Bio Age (cognitive age), and RELIQ (relational & emotional intelligence) combine into one rounded picture — not a single brittle digit.
It never goes stale
Your credential carries a "current as of" date and re-verifies on a cadence — quarterly on Verified, monthly on Profile — the way real professional certifications stay valid.
Built for two, as well
RELIQ for couples and a shared Household trend let you and a partner track relational intelligence together — six brain regions, mapped over time.
The real sample reports
These are the actual sample reports each instrument produces — opened straight from the live test sites. No mock-ups, no summaries.
The full verified intelligence report — six-region brain analysis, IQ-scale equivalencies, archetype, and career matches.

Cognitive measurement infrastructure for organizations
Schools, employers, and agencies use the ParkerCognition suite for verified, at-scale cognitive measurement — seat licenses, cohort assessment, white-label deployment, and API access. Enterprise volume from $99 per test.
Institutional licensing →Price above the commodity — because this isn't entertainment.

Questions worth answering
What is a verified cognitive credential?
A cognitive score that is interpretable, independently checkable, and kept current over time. Unlike a one-time test result, a ParkerCognition credential carries a plain-language interpretation, an IBM Quantum-backed verification certificate, and a re-verification cadence that keeps it from going stale.
How is Real World IQ scored?
Real World IQ is computed entirely on our servers from your answers and your pace. Each correct answer contributes to your base score, with a capped bonus for speed. The result is anchored to an interpretable scale and stamped with a verification reference. The scoring is never run in your browser, so it cannot be gamed.
Why do most brain-score apps give you a number you cannot use?
They sell entertainment scores with no interpretation, no verification, and no way to prove them to anyone. ParkerCognition gives you a Quantum-Verified Mirror Score™: a number with a meaning, a certificate, and a trend.
What makes the score verifiable?
Every verified score opens an immutable certificate that can be checked publicly at https://verify.advancedlearning.academy. Verification is backed by an IBM Quantum protocol — a credibility stamp no competitor can replicate.
