How to Read a Training Drill Diagram: A Beginner Coach's Decoder

It is 5:55 on a Tuesday evening. The light is starting to go, twelve kids are hanging off your legs asking when they can start, one parent is hovering, and in your hand is a printed drill card you found online at 11pm last night. It looked brilliant then. Now, on the grass, the arrows, dashed lines and little clusters of circles may as well be ancient hieroglyphics. So you do what most new coaches do: you bin the plan, roll a ball out, and play a scratch match while quietly feeling like a fraud.

Or maybe it's the other version of the same problem. You read a drill written out in plain words, "the first attacker plays a pass into the second attacker, who sets it back for the third to drive into the channel," and you understand every single word on its own, but by the end of the sentence you have no earthly idea what the drill actually looks like or how it works. The words are all English. The picture never arrives.

Here is the thing nobody tells you when you volunteer. The hard part of using a good drill often isn't the coaching. It is the reading, whether that's a diagram or a description. A drill diagram is a map, and like any map it has a legend. Beginners freeze because they try to read the picture before they find the key. Learn the small handful of symbols, and one simple habit, and you can run almost any session anyone hands you, whether it came from Football Australia, a coaching book, a YouTube still or an app.

This matters more than it sounds. Being able to decode a diagram isn't a party trick for badge-holders. It is the single thing that unlocks the entire library of drills that already exists in the world. A coach who can read diagrams has thousands of tried-and-tested activities to choose from. A coach who can't is stuck reinventing the same three games every week. Better access means better sessions, and better sessions mean better development for your players. Reading the picture is where it starts.

Why the diagram, not the drill, is where beginners stall

Most coaching advice assumes you are already fluent. Posts about effective drills for skill development or how to structure a MiniRoos session hand you the activity and trust you to picture it. That trust is the gap. The activity might be perfect for your U9s, but if you can't tell whether that arrow means "the player runs here" or "the ball is passed here," you will set it up wrong, the kids will do something different again, and you will conclude the drill is rubbish. It wasn't. The translation broke down.

The good news: the vocabulary is tiny. There are really only three types of line, a short list of shapes, and a dozen abbreviations doing all the work. One caveat before we start: not every diagram uses this vocabulary identically. Some sources use arrows for player movement and others for the ball, some use colour for teams and others for roles, some number the players and others number the sequence of actions. The next section explains why, and how to handle it. For now, learn the common core below, and it will get you through the large majority of what you're handed.

The one rule that saves you: find the legend first

Before you interpret a single arrow, look for the key. On a good diagram it lives in a corner or down the side, a little box that tells you what each symbol means. Find it first, every time. This is the load-bearing habit of the whole post, and here is why it matters so much.

There is no single global standard for drill diagrams. Conventions vary between manuals, coaching bodies and apps, and some of them directly contradict each other. The most common convention treats a solid arrow as a player's run and a dashed arrow as a pass. But respected resources flip it: Coaching American Soccer, for instance, uses a solid line for the ball (passes and shots) and a dashed line for a player's movement off the ball. Same two symbols, opposite meanings.

If you assume instead of checking, you will get it backwards, and the drill will collapse in front of the kids. So the rule is simple: never assume, always find the key. As Coaching American Soccer puts it, whichever conventions are chosen, they "must be used consistently across all diagrams presented to a team in order to avoid confusion." When you make your own diagrams later, pick one convention and stick to it religiously.

The three lines you must never confuse

Almost every diagram comes down to answering one question about each line: is this a player moving, a ball moving, or a player travelling with the ball at their feet? Three lines, three answers.

• Solid arrow: a player run. The player moves from A to B without the ball. Think of an attacker sprinting into space to receive.
• Dashed arrow: a pass, or the path of the ball. The ball travels along this line from one player to another, or towards goal.
• Wavy or squiggly line: a dribble. The player carries the ball at their feet along this path.

Commit that trio to memory and you have cracked most of the diagram. Just remember the caveat from the section above: a minority of sources swap the solid and dashed meanings, so glance at the key before you trust your instinct.

The core symbol vocabulary

Once the lines make sense, the shapes are quick. These are the pieces you will see over and over.

Colours and numbers do extra work. Two teams are usually shown in two colours (or filled versus hollow). Numbers or letters on the circles (1, 2, 3 or A, B, C) show the order players act in, or which player is which. If you see "1" with a ball and "2" in space, the sequence is almost always: player 1 does their thing first, then player 2.

The shorthand glossary

Diagrams lean on abbreviations to save space. You don't need all of them on day one, so here they are in two tiers: what to know before your next session, and what you'll pick up naturally as you coach more.

Terms you need before your next session

• GK: goalkeeper.
• SSG: small-sided game, for example 4v4 with no keepers.
• 1v1, 2v1, 3v2: the numbers of attackers versus defenders. "2v1" means two attackers against one defender.
• 1v1 to goal: one attacker tries to beat one defender and score, usually in a small channel.
• Grid: a marked square or rectangle that contains the activity.

Terms you'll hear as you get more experienced

• Overload: any situation with more players on one side than the other, like the 2v1 above, used to make success more likely for the team with extra numbers.
• Channel: a long, narrow grid, often used for 1v1s or dribbling.
• Station: one of several separate activities set up around the pitch that groups rotate through.
• Transition: the moment possession changes from one team to the other; a drill "working the transition" is training what players do the instant they win or lose the ball.

Keep this page bookmarked for your first few sessions, and the shorthand stops being a barrier fast.

Worked example: decoding a diagram cold

Theory is fine, but let's actually read one. Imagine you have been handed this: a 1v1 to goal.

Read it in the order the habits give you:

1. Find the shapes. A rectangle marked by four cones: that is the grid, your playing area. An open rectangle on the top edge with a triangle inside: a goal, defended by a goalkeeper (GK).
2. Find the players. A filled circle at the bottom with a small ball beside it (labelled A): your attacker, on the ball. A hollow circle in the middle (labelled D): the defender.
3. Read the lines. A wavy line runs from the attacker up towards goal: that is the attacker dribbling. A solid arrow points from the defender towards the ball's path: that is the defender's run to close down and intercept.

Put it in plain words and the whole thing resolves: the attacker starts on the ball at one end of a grid and tries to dribble past a defender to score in the goal at the far end; the defender starts central and moves to stop them. That is it. You have gone from "what am I looking at" to a game you can run.

Setting it up: four cones for a grid roughly 10 by 15 metres, one small goal, one keeper. Attacker on the ball at one end, defender in the middle. First attacker to beat the defender and score wins, then swap roles and rotate. Two coaching points to keep in your back pocket: encourage the attacker to change speed (slow to draw the defender in, then explode past), and encourage a positive first touch that moves the ball forward into space, not sideways. Both are exactly the kind of individual skill focus that development at this age is built on, over any interest in the scoreline.

A drill diagram is not the session

Once you can read a diagram cleanly, it's tempting to think the job is done: cones out, diagram followed, session delivered. It isn't quite that simple, and the difference matters.

A diagram tells you the mechanics: where players start, how they move, where the ball goes. What it can't tell you is what to actually watch for while it's happening, what mistakes to expect, how to make it harder when players find it easy, or how to make it easier when they don't. Take the 1v1 to goal above. The diagram shows an attacker beating a defender to score. It doesn't tell you that a heavy first touch is the single biggest reason kids that age lose the ball, or that you should be watching for a change of pace before contact, not after it. That part is coaching, and no diagram does it for you, however well it's drawn.

The diagram tells you what happens. The coaching points tell you why it matters. Read the picture to set the drill up correctly, then bring your own eyes to make it worth running.

Setting it up on the grass

Reading the diagram is half the job. Translating it to a field of excitable seven-year-olds is the other half, and a couple of small habits make it painless.

• Colour-code your cones. Football Australia's own MiniRoos coaching guidance suggests colour-coordinating cones so you and the players can see the different parts of a session at a glance. Use one colour for the grid boundary and another for gates or targets, and the setup reads itself.
• Use bibs as start markers. The same guidance recommends placing a bib where you want each player to begin, so children can see exactly where to stand. It saves you repeating "no, over there" ten times.
• Walk it once before they arrive. Set the drill up and physically walk through the first repetition yourself, playing the part of the attacker. If the diagram made sense, the walk-through will confirm it. If it didn't, you will find the confusing bit while there is still time to fix it, not in front of the group.
• Demonstrate, don't describe. Young players learn by watching far more than by listening. Show one repetition, or ask a confident player to, then let them play. Save the coaching points for the natural pauses.

Do this two or three times and something clicks. The diagram stops being a wall and becomes what it was always meant to be: a fast, silent way for one coach to hand a good idea to another.

Frequently asked questions

What does a dashed line mean on a soccer drill diagram? On most diagrams a dashed arrow shows a pass or the path of the ball, while a solid arrow shows a player running without the ball. Be aware that some resources reverse this, using dashed lines for player movement, so always check the diagram's key before you start.

What is the difference between a solid arrow and a wavy line? A solid arrow usually means a player runs from one point to another without the ball. A wavy or squiggly line means the player dribbles, travelling with the ball at their feet along that path.

What do GK, SSG and 2v1 mean in a drill? GK is the goalkeeper. SSG is a small-sided game, such as 4v4. 2v1 describes the numbers involved: two attackers against one defender, an "overload" that deliberately gives the attacking side the advantage.

Do all drill diagrams use the same symbols? No. There is no single global standard. Football bodies, coaching books and apps each use their own variants, and some contradict each other. The symbols in this guide are the most common, but the safe habit is to find each diagram's legend first.

How do I run a drill if I still can't picture it? Set it up physically and walk through the first repetition yourself, playing the attacker. Acting out the movement almost always reveals what the diagram meant, and if it doesn't, you have found the confusing part with time to adjust before your players arrive.

Every diagram you decode adds another activity to the collection you can actually use, and that collection is the difference between a coach who plays the same scratch match every week and one whose players are constantly challenged in new ways. Once you understand the language of diagrams, tools like session builder apps become much easier to use too, because you can spend your time choosing the right activity for your players instead of decoding the picture. Print the next one out, find the key, read the lines, and walk it through. The kids will never know it was a foreign language to you an hour ago.
