Understand a Young Athlete's
Development Potential

The algorithm treats your child's own kinanthropometric data — current height, sitting height, and arm span — as the primary anchor. When extended family heights are unavailable or estimated, the system automatically adjusts weighting coefficients and shifts reliance to the child's biological markers. Result: a slightly wider confidence interval (±3.5 cm vs. ±2.1 cm) but clinically valid for development guidance.

The report analyses young athletes aged 4–18 years, with assessments entered and purchased by a parent, guardian or coach. For PHV (Peak Height Velocity) tracking, the highest-yield window is ages 8–14, where annual reassessments reveal trajectory shifts and sport-specific timing opportunities.

No. A standard tape measure and a flat wall are all you need. The assessment wizard walks you through each measurement with visual step-by-step guides. Optional field test results (sprint, jump) can be added if available — but the full report is complete without them.

Yes. Reports are built on internationally recognised LTAD standards and validated Mirwald / Khamis-Roche protocols — used by coaches and talent identification specialists as a standard reference. For academy bulk testing, our Expert Coach Assessment ($99) adds supervised field testing with advanced metrics.

Yes. Your account supports unlimited children — each with their own independent profile, report history, and growth tracking dashboard. Each assessment is a separate one-time purchase.
