The High10 Score™ & Science
142 questions. Six dimensions. One number that predicts the trajectory of your career, health, relationships, wealth, mindset, and environment — and the entry point into a 90-day coaching protocol with a measurable guarantee.
Independent validation
In 2023, behavioral researchers at Yale ran a 1,204-participant study to test whether the High10 Score™ could predict downstream performance — across income trajectory, relationship stability, and self-reported wellbeing — better than the generic personality inventories widely used in executive coaching.
The conclusion was unambiguous: the assessment demonstrated strong predictive validity and outperformed four legacy inventories in test-retest reliability, convergent validity, and 12-month behavioral forecasting. High10 is the only consumer-facing life-performance assessment to carry an institutional validation of this caliber.
What the score measures
The 142-question High10 Score™ maps performance across six life domains. Each dimension produces its own sub-score, its own benchmark against the top 10% in that category, and — once you enter the 90-day protocol — its own weekly KPI your coaching pod will move.
Trajectory velocity, decision quality under pressure, leadership signal, and the weekly output ceiling you've quietly accepted as your maximum. Top 10% benchmark: 84th-percentile performance under sustained cognitive load.
Sleep architecture, recovery debt, training compliance, and the metabolic markers that quietly tax cognitive performance every afternoon.
Attachment style, conflict fluency, network density, and the quality — not the quantity — of the five relationships doing the most work in your life.
Income-to-effort ratio, savings velocity, negotiation patterns, and the financial ceiling maintained by decisions you made three years ago.
Identity-level beliefs, recovery speed from setbacks, attention control, and the operating system you're running on when no one is watching. This is the dimension Yale found to be the strongest single predictor of 12-month behavioral change.
Physical space, peer cohort, calendar architecture, and the inputs your environment is forcing into your nervous system every hour of every day.
The 90-day methodology
The High10 Score™ is the front door. The four chapters that follow are the building. Every client moves through them in sequence — and the fourth is where the guarantee lives or dies.
Five minutes, 142 questions, scored across six dimensions. You receive a sub-score for each domain, a composite High10 Score, and a personalized benchmark against the top 10% of your peer cohort. No fluff. No "discover your archetype." A diagnostic instrument.
Day 0Within 48 hours, a vetted four-person pod is assigned — a master coach, a domain specialist, an accountability partner, and a performance analyst. You meet them. They meet your score. Together, you set six weekly KPIs tied to the sub-scores that came back lowest.
Days 1–7Twelve weekly sessions. Daily micro-actions in the High10 app. Live coach check-ins. Streak-protected habit architecture. The protocol is built to move at least three of your six sub-scores by a statistically meaningful margin — and we publish the cohort data on what moves and what doesn't.
Days 8–84At day 90, you re-take the High10 Score™. If your composite score and your three targeted KPIs haven't moved, you receive a full refund — no paperwork, no exit interview. The guarantee exists because the methodology works, and the validated assessment is what makes it enforceable.

The 90-day guarantee
