Tennis Development Glossary

Plain-English definitions and on-court coaching cues for players, parents, and coaches across all development stages.

Learning

30 terms

How children learn movement, and how coaches teach it.

Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

Developing the whole child across several areas at once: technique, tactics, movement, mind and social skills. Also means building a broad base of movement from many activities, not only tennis.

Say it on court

“We train the athlete and the person, not just the forehand.”

Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

Teaching the same skill through many different drills, games and conditions so the child learns to use it anywhere.

Say it on court

“Same shot, ten different games.”

Gradual progression
CoachesParents
Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

Adding difficulty in small steps, from simple to complex and from easy to hard, so the child keeps succeeding while being stretched.

Say it on court

“We add one new challenge at a time.”

Learning through play
ParentsCoaches
Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

Using games as the main teaching tool at young ages. Children stay engaged longer and learn to use skills in real situations.

Say it on court

“If it looks like they're just playing games, that's the plan working.”

Development areas
CoachesParents
Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

The areas every session and every player report should cover: technical, tactical, physical (movement), mental, and social/communication. Competition and organization are added for older players.

Say it on court

“Here's where she's at in each of the five areas.”

Motor learning
CoachesParents
Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

How the body and brain learn a movement until it becomes automatic. Real learning shows as improvement, consistency, retention over time, and the ability to adapt the skill to new situations.

Say it on court

“A good lesson isn't one perfect shot. It's a shot that still works next week.”

Stages of learning
CoachesParents
Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

Learning a skill moves through three stages: rough (the child gets the general idea but the movement is clumsy), refined (the movement becomes smoother and more accurate), and flexible (the player can adapt it under pressure and in new situations).

Say it on court

“He's in the rough stage with the serve. Clumsy is normal right now.”

Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

A movement that has been practised until it reaches a goal reliably, with a high success rate and little wasted energy.

Say it on court

“Skills are built through repetition with purpose.”

Open skill
CoachesParents
Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

A skill performed in a changing, unpredictable environment, like tennis, where every incoming ball is different. Players must read and react, not just repeat.

Say it on court

“Tennis is an open skill. The drill is only useful if it transfers to the match.”

Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

A skill performed in a stable, predictable environment, such as a gymnastics routine. In tennis, the serve is the closest thing to a closed skill.

Say it on court

“The serve is the one shot where you're in full control.”

Closed drill
CoachesPlayers
Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

A drill focused on technique only, with no decisions to make. For example, repeated fed balls from a basket.

Say it on court

“Basket feeding: just focus on the swing.”

Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

A drill with limited, known choices. The player knows the options but not exactly which ball is coming.

Say it on court

“It's either a forehand or a backhand. Read it early.”

Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

A live-ball drill with a few rules or targets that limit the options while still demanding decisions.

Say it on court

“Live rally, but you can only win the point cross-court.”

Open drill
CoachesPlayers
Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

A drill or game that looks like real match play, where the player must read, decide and execute.

Say it on court

“Now play it out. You make the decisions.”

Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

Mixing different shots and situations in unpredictable order. It feels harder in the moment but produces better learning than repeating one shot in a block.

Say it on court

“It feels messier, but it sticks better.”

Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

Breaking a stroke into its parts and working on each one separately. Useful for fixing one specific element in older players.

Say it on court

“Let's isolate just the finish for five minutes.”

Game-based approach
CoachesParents
Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

Teaching technique and tactics together through games, so children understand why a shot is used while learning how to hit it. Often uses guided discovery.

Say it on court

“We start with the game, then fix the technique it exposes.”

Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

A step-by-step model where technique is built first and tactics and match play come later. The coach makes all the decisions and the student follows.

Say it on court

“Useful for specific fixes, but not our default with kids.”

Guided discovery
CoachesParents
Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

A teaching style where the coach sets up a task or asks a question and lets the child find the answer. Children remember what they discover more than what they are told.

Say it on court

“Where did the ball go when your feet were wide? Why do you think that happened?”

Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

The range of ways a coach can run a task: command (coach decides everything), practice (player works at own pace on set tasks), reciprocal (players coach each other), and guided discovery.

Say it on court

“Pick the style that fits the goal, not the one that's habit.”

Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

The coach decides what, when and how, and players follow. Efficient for organization and safety, weaker for independence.

Say it on court

“Everyone on the baseline, go on my whistle.”

Reciprocal style
CoachesPlayers
Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

Players work in pairs, one performing and one observing and giving feedback against a simple checklist.

Say it on court

“Watch your partner's split-step and tell them if it's on time.”

Feedback
CoachesParentsPlayers
Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

Information a player gets about their performance. Internal feedback comes from their own senses (how it felt, how it sounded). External feedback comes from outside: a coach's comment, a video, where the ball landed.

Say it on court

“How did that one feel? Now look where it landed.”

Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

Showing the movement before explaining it. Young children copy what they see far better than what they hear.

Say it on court

“Watch me first, then you try.”

Session structure
CoachesParents
Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

A lesson has a warm-up and activation phase, a main phase with varied multilateral work, and a closing phase with a game and review.

Say it on court

“We always finish with a game and one thing to remember.”

Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

Watching a player systematically, from close and from a distance, before deciding what to correct. Observe, intervene, then check.

Say it on court

“I watched ten balls before saying anything.”

Evaluation
CoachesParents
Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

Checking progress against the stage goals at regular intervals, so decisions about moving up are based on evidence.

Say it on court

“Our check-in shows he's secure on 4 of 6 orange goals.”

Training load
CoachesParents
Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

How much work a player does: number of balls hit, time on court, distance covered, rest. Even without lab testing, coaches should track it roughly.

Say it on court

“We keep the volume sensible so she stays fresh and healthy.”

Target games
CoachesPlayersParents
Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

Games where players score by hitting a hoop, cone or court zone. They teach direction and aim without a lecture.

Say it on court

“Land it in the box and score a point.”

Video analysis
CoachesPlayersParents
Red (Ages 5–8)
Orange (Ages 7–10)
Green (Ages 9–12)
Yellow (Ages 11+)

Filming practice or matches to review technique and decisions. Players often understand a correction faster once they see it.

Say it on court

“Let's watch that serve back.”
