OTK is following the U.S. Tennis Association NTRP rating system.

The rating categories are simply here to guide you. You may find that you play above or below the category, depending on your competitive ability. The category you choose is not meant to be permanent and may be adjusted as your skills change or as your match play demonstrates the need for reclassification.

NTRP LEVEL: 1.0 - 1.5 (Beginner)

This player has had limited experience with stroke development and is still working primarily on getting the ball into play. This player is not yet ready to compete.

NTRP LEVEL: 2.0 (Beginner plus)

This player needs on-court experience, with an emphasis on play. This player struggles to find an appropriate contact point, needs stroke development/lessons and is not yet familiar with basic positions for singles and doubles.

NTRP LEVEL: 2.5 - (Intermediate minus)

This player is learning to judge where the ball is going although court coverage is weak. This player can sustain a slow rally with other players of same ability.

Potential limitations: Grip weaknesses; not attempting full swing on serve; inconsistent toss on serve; limited transitions to net

NTRP LEVEL: 3.0 (Intermediate)

This player is consistent when hitting medium pace shots, but is not comfortable with all strokes and lacks control when trying for directional intent, depth, or power.

Potential limitations: consistency when applying or handling pace; difficulty handling shots “outside of their strike zone”; can be uncomfortable at the net.

NTRP LEVEL: 3.5 (Intermediate plus)

This player has achieved improved stroke dependability with directional control on moderate shots, but still lacks depth and variety. This player exhibits more aggressive net play, has improved court coverage, and is developing teamwork in doubles. 

Potential limitations and strengths: “This is the level at which it begins to be about what skills a player can display on court, not what they can’t.” Players at this level may start to utilize mental skills related to concentration, tactics and strategy.

NTRP LEVEL: 4.0 (Advanced minus)

This player has dependable strokes, including directional control, depth and the ability to alter distance of shots on both forehand and backhand sides during moderately paced play, plus the ability to use lobs, overheads, approach shots, and volleys with more success.

Potential strengths: Less likely to beat themselves; more dependable second serve; recognizes opportunities to finish points.

NTRP LEVEL: 4.5 (Advanced)

This player has begun to vary the use of pace and spins, has good movement, can control distance and depth of shots, and is beginning to develop game plans according to strengths and weaknesses. This player can hit the first serve with power and accuracy and can place the second serve. This player tends to overhit on difficult shots. Aggressive net play is common in doubles.

Potential strengths: Points are won and lost off the serve more often; better able to cover weaknesses; beginning to develop a weapon around which their game can be built.

NTRP LEVEL: 5.0 (Advanced plus)

This player has good shot anticipation and frequently has an outstanding shot or attribute around which their game can be structured. This player has the confidence to regularly hit winners or force errors off of short balls and can put away volleys, can successfully execute lobs, drop shots, half volleys, overheads, and has good depth and spin on most second serves.
