How Many Officials are in Badminton?
There is a total of 10 to 13 officials in a badminton tournament. The variation is on the line judges. The BWF is recommended to have 10 line judges per court. But some tournaments will only have 8 line judges.
What Are The Officials of Badminton?
They include 1 referee, 1 umpire, 1 service judge, and 8 to 10 line judges.
Referee in Badminton
In the world of professional badminton, the Referee is the ultimate orchestrator—the “Supreme Court” of the shuttlecock. While the players command the court, the Referee commands the entire tournament landscape.
Here is a look at why they are the most powerful person in the building:
The Ultimate Authority
The Referee isn’t just watching the lines; they have absolute jurisdiction over every matter affecting the game. Their power extends far beyond the net, covering everything from player conduct in the locker rooms to disputes on the court. If there’s a crisis, the Referee has the final word.
The General of the Officials
Think of the Referee as the commander-in-chief. Every other official on the floor—the Umpire, the Service Judge, and the Line Judges—reports directly to them. While the Umpire manages the individual match, the Referee manages the entire ecosystem, ensuring every official is performing to the highest standard.
The Master of Logistics
A tournament’s pulse is its schedule, and the Referee holds the keys to the clock. They have the final authority to:
- Approve practice sessions: Ensuring players have fair access to the courts.
- Validate match schedules: Balancing the timing to keep the tournament running like clockwork.
- Handle disruptions: Making the tough calls when weather, injuries, or delays threaten the flow of play.
Fun Fact: While an Umpire can hand out a yellow or red card, only the Referee has the power to disqualify a player from the entire tournament.
What does the referee do in badminton?
The responsibilities of the referee :
- Ensure the correct implementation of rules and regulations according to international badminton standards.
- Plan and come out with a schedule and order of play.
- Ensure the smooth running of the tournament on each day.
- If any issue happens, the referee will liaise with the umpire and line judge officers.
- Doing amendments to the schedule and drawing.
- Ensure all equipment used in a tournament is qualified according to BWF standards.
- Ensure the availability of all tournament reports.
You will not see referees carry out their duty on the court. They are more of a backend force. Referees will only show faces if any special issues are happening. If the umpire raises any conflict or issues, the referee will exist and try to solve them. The decisions made by the referees are generally final.
Level of Referee
There are two levels of the international referee. They are:
- BWF Accredited.
- BWF Certificated – the highest level.
Badminton Referee Training and Assessment
The Confederation carries out the referee training and development programs. BWF will conduct the training seminars and courses to ensure all the participants have sufficient knowledge of badminton rules, equipment, players, etc.
All the potential referees are being trained and assessed by the National Badminton Associations. Referees who complete the training, are knowledgeable, and have good experience will be further assessed to become international referees who are BWF Accredited or Certified.
The referee of the competition has the authority to choose the qualified candidates to join the Refereeing team. The retirement age for a badminton referee is at age 65.

Umpire
While the referee is taking care of the entire tournament, the umpire is in charge of the badminton court and all the matches in a tournament.
The umpire is sitting on the tall umpire chair in front of the net. The umpire is responsible for the main penalty, judging if the receiver makes a foul when a rally is served. Besides, the umpire will also judge on his side if a shuttle is inside or outside the court.
Badminton umpire qualifications
The levels of umpire can be categorized into 3, from third grade to first grade.
The third-grade umpire can directly take the exam and get approval from the sports departments of counties, districts, and universities.
If you are already a third-grade umpire, you can take more badminton umpiring at the city or district level because this level of sports authority can approve you to become a second-grade umpire.
To become a first-grade umpire, you must regularly participate in the umpiring work at the provincial, county, or state level. It would be best if you were recognized by the local sports authority to have the opportunity to take the exam and be approved as a first-grade umpire.
National Umpire
To become a national umpire, first, you must have a higher level of knowledge about badminton. Not only do you need to grasp all the rules and regulations, but you also need to understand and use them freely and correctly.
Secondly, you must understand the rules of drawing in badminton matches and participate in the drawing process in some competitions.
In addition, every international or national umpire has the responsibility and obligation to train local-level umpires, and you can ask them for help.
Finally, it would help if you did not forget to constantly contact the local provinces, municipalities, sports competitions department, and badminton associations. Often participate in various activities and assessments organized by them to recommend that you participate in the national umpire assessment at key moments.
3 Levels of Test
Generally, most of the Badminton Association will conduct national-level umpire examinations every two years.
The association will issue documents to the provincial and regional sports committees and allocate the venues for examination.
The candidates who are recommended by local committees from all over the country will take the exam. Most of the examinations include 3 sessions: written test, oral test, and the on-the-spot umpire.
The content of the written test will include regular umpire law, drawing arrangement, and English language.
The oral test mainly tests the candidates to listen to some conversations. The examiners will observe their actions and measure the candidate’s ability to express and understand the rules.
The on-the-spot umpire test will test the level of the candidate. They will get tested on their control ability, personality, and English speaking level.
First-grade umpires who are preparing to apply for national-level umpires can refer to the Law of Badminton, approved by BWF, and the “Badminton Referee Handbook,” which was published by an authorized badminton association from the respective country.
What is the umpire’s role in badminton?
- Ensure the enforcement of the badminton rules in competition. Promptly pronounce the foul committed by the players.
- Ruling on the appeal made by the player before the next serve.
- Ensure that players and spectators are kept informed of the progress of the game.
- Have the right to assign or remove a line judge or service judge after consultation with the referee.
- Arrange for unexecuted duties when technical officers are insufficient.
- When the technical officer is blocked from sight, perform his duties for players to do a “re-service.”
- Record and report to the referee all matters related to the rules of all the matches.
- Only submit those appeals related to the badminton rules to the referee. You must file this type of appeal before the next serve. If the match is over, it should be filed before the complainant leaves the court.
- Effectively interact with coaches, players, and other volunteers.
- Be a decision-maker and make sure of fair play in every game.
The retirement age for a badminton umpire is at the age of 55.
Service Judge
What is a service judge in badminton?
The service judge sits on a low chair in front of the net opposite the umpire.
What is the role of the service judge?
There are 2 main responsibilities for a service judge. The first one is making a ‘service fault’ call if a player is fouled when doing the serve. The second one is to provide a new shuttle if the player requests a shuttle change.
You may find it in some tournaments. No service judge is being assigned. If this is the case, then the umpire will also be taking up the role of service judge.
Badminton Line Judge Training and Assessment
To become a qualified service judge, you will undergo the same training and assessment as those who want to become an umpire. Therefore, you can refer to the part about the umpire if you want to know how to become a service judge.
The retirement age for a badminton service judge is at age 55.
Line Judges (Linesmen)
The line judge is placed at each line of the badminton court to look after whether a shuttle that lands is in or out of the court near the line they are appointed to look after.
How many line judges are there in badminton?
As mentioned in the beginning, the number of line judges can be different in different matches. Some tournaments have 10 line judges, while some may have 8.
A midline judge on both sides of the court determines whether the serve is in the wrong zone.
A baseline judge on both sides determines whether the shuttle is out of the line and whether the doubles make a long serve.
Two sideline judges on both sides of the court determine whether the shuttle is out of the line.
It’s the umpire’s responsibility to ensure he has sufficient line judges on duty during a tournament being held.
What are the roles and responsibilities of a line judge in badminton?
Requirements for the line judge are:
They should sit on the line being assigned to him. The best position is to face the umpire. The actual sitting distance between the line judges with the court is about 2.5 to 3.5 meters.
1. When the shuttle is falling outside the boundary, the line judge needs to shout “out” loud and clear to report that the shuttle has landed “outside the boundary.” At the same time, the arms need to be raised sideways so that the umpire can see clearly.
2. If the shuttle is landed within the line boundary, the line judges only need to point to the line with their hands.
3. If the eyesight of the line judge is blocked, they need to use both hands to cover their eyes immediately to signal to the umpire that they miss the eye judgment.
Badminton Line Judge Training
BWF issues no course or certification for the training of line judges. Therefore, the path to becoming a qualified line judge will with different for many countries. Since the position is not as important as an umpire or service judge, thus, most of the requirements for someone to become a line judge are rather lenient.
In addition, the implementation of “Hawk-Eye” helps to share the jobs with the line judges.
About “Hawk-Eye”
It used to be the line judges who would have the final judgment if a shuttle landed inside or outside the line in a badminton match. However, it is difficult to ensure 100% accuracy by the line judge’s eye, which leads to many controversies.
Because of this, it is finally resolved with the introduction of “Hawk-Eye.”
The technical principle is not complicated, and it is exact. The system consists of 8 or 10 high-speed cameras, four computers, and a large screen.
The official name of “Hawk-Eye” is “Instant Replay System,” first used in tennis. The system consists of 10 cameras that track the flying tennis ball and feed back information to the connected computer, calculating the simulated trajectory.
When a player has objected to the umpire’s decision and applies for playback, it will display the computer-simulated trajectory on both the TV and the large screen.
The “Hawk-Eye” takes no more than 10 seconds from data collection to results demonstration, and the error is guaranteed to be less than 1%.
Once you are qualified to be a line judge, you will not need any additional training. The line judge can accumulate their judging skill and experience by taking part in more important tournaments.
There is no retirement age for line judges. As long as your health and your eyes are in good condition, you can get the position.
What Do The Officials Wear In Badminton?
The uniforms of badminton officials need to be well distinguished from the players. Also, their shirt colors cannot be too bright, following the rules of badminton. To make it have clear differences, badminton officials are wearing a single color polo shirt with black pants.
Linesmen or service judges are not in the limelight for the sport. Thus, they are allowed to wear less formal attire. However, they still need to put on a decent uniform for a competition to be presentable.
Now, it is prevalent for officials to wear sponsored badminton uniforms.
