Not all NTRP ratings are created equal. Section strength varies based on player pool size, competitive depth, and historical championship performance.
The National Tennis Rating Program is the official USTA system with 11 levels from 2.0 to 7.0. Updated once per year based on match results. Free for all USTA members.
Universal Tennis Rating uses a continuous scale and factors in score margin, not just wins and losses. Updates frequently with new match data. 1M+ rated players worldwide.
The World Tennis Number is the ITF's global standard. Scale runs from 40 (beginner) to 1 (best) - lower is better, like golf. Free, algorithm-based, and growing in international adoption.
