Developmental Intelligence for Youth Soccer
EQI quantifies training efficiency across five developmental domains, three computation tiers, and one index that tells the truth. Stop guessing. Start measuring.
The Problem
Coaches train by intuition. Sessions live in spreadsheets. Parents see effort but never development. Directors see costs but never quality. The entire youth development ecosystem runs on guesswork.

The Model
EQI combines where training minutes go, how closely they match the ideal developmental profile for each age band, and the quality of delivery — into a single index between 0 and 1.
Where are the minutes going? Every session is decomposed into five developmental domains using calibrated density vectors.
How close to the ideal? Cosine similarity between actual domain distribution and the age-band anchor profile, adjusted by the Recalibration Factor.
How well was it delivered? Hours, Diversity, Instruction, Evaluation, Recovery — five multiplied factors enhanced by the Consistency Index.

The Platform
Log sessions, compute EQI in real-time, track development plans, and monitor per-player progress across all five domains.
Explore→See your child's domain health, log outside activities, submit recovery data, and stay connected through coach notes and age-group chat.
Explore→Academy-wide health indices, age group comparison, coach assignments, longitudinal trends, and quality benchmarking at a glance.
Explore→Longitudinal Tracking
Diagnostic
Immediate misalignment detection. A volunteer coach runs the wrong program — EQI flags it on day one.
Feedback Loop
Coach adjusts after EQI data. Over-structured training shifts to include more free play. The index improves week by week.
Seasonal Arc
Full cycle captured. Preseason, midseason, tournament blocks, holiday regression, rebuild — every phase visible in the data.
Developmental Arc
Complete journey. Phase transitions, coach absence regression, recovery, peak performance. The model proves its value over time.
