The referee is the person responsible for enforcing the Laws of the Game (LOTG) during an association footballmatch. He or she is the final decision-making authority on all facts connected with play, and is the only official on the pitch with the authority to start and stop play and impose disciplinary action against players during a match. At most levels of play the referee is assisted by two assistant referees (formerly known as linesmen), who are empowered to advise the referee in certain situations such as the ball leaving play or infringements of the Laws of the Game occurring out of the view of the referee; however, the assistant referees' decisions are not binding and the referee has authority to overrule an assistant referee. At higher levels of play the referee may also be assisted by a fourth official who supervises the teams' technical areas and assists the referee with administrative tasks, and, at the very highest levels, additional assistant referees and/or video assistant referees.
The International Football Association Board (IFAB) determines the Laws of the Game. Referees and other game officials are licensed and trained by its member national organisations.
Referees' remuneration for their services varies between leagues. Many are wholly amateur, some may be paid a small fee or reimbursed for expenses, and, in some countries, a limited number of referees – mainly those who officiate in their country's top league – are employed full-time by their national associations and receive a retainer at the start of every season plus match fees.
Each national organisation recommends its top officials to FIFA to have the additional honour of being included on the FIFA International Referees List. International games between national teams require FIFA officials. Otherwise, the local national organisation determines the manner of training, ranking and advancement of officials from the youngest youth games through professional matches.
The referee's powers and duties are described by Law 5 of the Laws of the Game.These include:
Modern day referees and their assistants wear a uniform consisting of a jersey, badge, shorts and socks: until the 1950s it was more common for a referee to wear a blazer than a jersey. Traditionally that uniform was almost always all black, unless one of the teams was wearing a very dark jersey in which case the referee would wear another colour of jersey (usually red) to distinguish themself from both teams. At the 1994 World Cup finals, new jerseys were introduced that gave officials a choice of burgundy, yellow or white, and at the same time the creation of the Premier League in England saw referees wear green jerseys: both changes were motivated by television considerations. Since then, most referees have worn either yellow or black, but the colours and styles adopted by individual associations vary greatly. For international contests under the supervision of FIFA, Adidas uniforms are worn because Adidas is the current sponsor. FIFA allows referees to wear five colours: black, red, yellow, green and blue. Along with the jersey, referees are required to wear black shorts, black socks (with white stripes in some cases), and black shoes. The badge, which displays the referee's license level and year of validity, is often affixed to the left chest pocket.
All referees carry a whistle, a watch, penalty cards, a data wallet with pen and paper, and a coin for determining which team has the choice of ends or kick-off. Most are encouraged to have more than one of each on them in case they drop a whistle or a pen runs out and so on. Often, referees utilise two watches so that they can use one to calculate time lost for stoppages for the purposes of added time. At the highest levels, referees wear a full duplex radio with customised headset to communicate between with their assistants, and assistant referees use electronic flags, which send a signal to the referee when a button is pushed.In matches with goal-line technology, referees will have on their person a device to receive the system's alerts.
Referees use a whistle to help in match control. The whistle is sometimes needed to stop, start or restart play but should not be used for all stoppages, starts or restarts. FIFA's Laws of the Game document gives guidance as to when the whistle should and should not be used.Overuse of the whistle is discouraged since, as stated in the Laws, "A whistle which is used too frequently unnecessarily will have less impact when it is needed." The whistle is an important tool for the referee along with verbal, body and eye communication.
Before the introduction of the whistle, referees indicated their decisions by waving a white handkerchief. The whistles that were first adopted by referees were made by Joseph Hudson at Mills Munitions in Birmingham, England. The Acme Whistle Company (based at Mills Munitions Factory) first began to mass-produce pea whistles in the 1870s for the Metropolitan Police Force. It is frequently stated the referee's whistle was first used in a game between Nottingham Forest and Sheffield Norfolk in 1878; however the last such fixture known to have taken place between the two clubs was in 1874. The Nottingham Forest account book of 1872 apparently recorded the purchase of an "umpire's whistle" and in 1928 an article by R M Ruck about his playing days in the early 1870s referred to the use of a whistle by umpires to indicate an infringement.
The whistle was not mentioned in the Laws of the Game until 1936 when an IFAB Decision was added as footnote (b) to Law 2, stating "A Referee's control over the players for misconduct or ungentlemanly behaviour commences from the time he enters the field of play, but his jurisdiction in connection with the Laws of the Game commences from the time he blows his whistle for the game to start."
In 2007, when IFAB greatly expanded the Laws of the Game, an Additional Instructions section became available, a full page of advice on how and when the whistle should be used as a communication and control mechanism by the referee.
Referees in football are first described by Richard Mulcaster in 1581.In this description of "foteball" he advocates the use of a "judge over the parties". In the modern era, referees are first advocated in English public school football games, notably Eton football in 1845. A match report from Rochdale in 1842 shows their use in a football game between the Bodyguards Club and the Fearnought Club.
In the early years of the codified sport it was assumed that disputes could be adequately settled by discussion between gentlemen players who would never deliberately commit a foul. However, as play became more competitive, the need for officials grew. Initially there existed two umpires, one per team, who could be appealed to with the referee (the game's timekeeper) being "referred" to if the umpires couldn't agree.
The promotion of referees to the dominant position they occupy today, and the reformation of umpires into the linesmen role, occurred as part of a major restructuring of the laws in 1891.
The predominant system of positioning and division of responsibility used by football match officials throughout the world is known as the Diagonal system of control (DSC).
The referee has final decision-making authority on all matters. The referee is assisted by two assistant referees who advise the referee. An assistant referee's judgement is enforced only if the referee accepts that judgement, and the referee has the authority to unilaterally overrule an assistant referee. The referee is the only official empowered with starting and stopping play, and meting out disciplinary actions such as cautions or send-offs.
The two assistant referees are instructed by the referee to each patrol half of a single touchline on opposite sides of the field. For example, on a field running north–south, one assistant referee (AR) would run on the eastern touchline from the north goal line to the halfway line, while the other assistant referee would run on the western touchline from the south goal line to the halfway line. In general, the assistant referees' duties would be to indicate (using their flags) when an offside offence has occurred in their half, when a ball has left the pitch, and if a foul has been executed out of the view of the referee (typically in their quadrant of the field). Generally, the ARs will position themselves in line with either the second to last opponent or the ball – whichever is closer to the goal line – to better judge offside infractions. However, the assistant referee will have specific positioning with respect to corner kicks, penalty kicks, and throw-ins.
The referee patrols the length of the field to cover the ground not covered by their two assistants, generally running in a diagonal pattern from the southeast quadrant of the field towards the northwest quadrant; hence the term "diagonal system of control" (DSC). Note that this pattern is not a specific route but a general guideline that should be modified to the style of play, nature of the game, the location of play at a given time, etc. In some cases the referee may even exit the field if it aids in their decision-making ability. The main idea is that the referee and assistants using the DSC should be able to position themselves quickly and easily to observe the important aspects of play (offside, ball in or out of play, goal-scoring opportunities, challenges for the ball) from multiple angles with multiple sets of eyes.
Note that the description above refers to a left diagonal system of control, known as "running a left" or "standard diagonal". If, before the match, the centre referee on this field decides to run from southwest to northeast, then the assistants must position themselves accordingly and the result will be a right diagonal system of control, otherwise referred to as "running a right" or "reverse diagonal".
In many cases in England, referees now use more of a 'curve' based on a line running from the edge of the 18 yard box, and when near the centre circle they then curve to a line level with the other 18 yard box line. This is similar to the diagonal system, but with the speed of modern football it is easier to keep up with play. This also helps the referee avoid being in a common "passing lane" through the centre circle itself.
In international matches the left-wing diagonal shown above has been universal since the 1960s. It is now predominant across the world. England until recently was an exception to this convention. Until 1974 referees in the Football League were required to run both diagonals during a match, most opting to run from right wing to right wing in the first half before switching to the left-wing diagonal for the second half. The chief reason for this alternation was to avoid linesmen wearing down the same part of the touchline during matches – this was important given the generally lower quality of pitches at the time. However switching diagonal was also justified in terms of allowing officials to patrol different areas of the field during games. From the 1974–75 season English referees were allowed to run the same diagonal throughout the same match. Most initially opted for the right-wing diagonal although over the years the left-wing diagonal became increasingly popular and the preferred choice of most referees by the early 2000s. From 2007–08 the left-wing diagonal has been mandatory in English professional football although some referees at lower levels still use the opposite approach.
Its implementation as a standard practice for referees is attributed to Sir Stanley Rous, former referee and President of FIFA from 1961 to 1974.
While the Laws of the Game mandate a single referee with assistants as described above, other systems are authorized either experimentally or explicitly by some governing organizations.
The dual system, has two referees with no assistants.The system is used some matches played under the rules of the National Federation of State High School Associations (NFHS) in the United States, and in other youth or amateur matches. Both referees have equal authority, and the decision of one referee is binding on the other. Each referee is primarily responsible for a specific area of the field similar to those of the assistant referees in the diagonal system, except that the referees are allowed and encouraged to move away from the touch line into the field, particularly as play approaches the goal lines. Like the assistant referees in the diagonal system, each referee is responsible for patrolling one touch line and one goal line and determining possession for the restart if the ball goes out of play on either of those two boundaries.
Positioning in the dual system is similar to that used by officials in basketball: each referee is either termed the "lead" or the "trail", depending on the direction of the attack. If the attack is against the goal to the referee's right (when facing the field from their assigned touch line), then that referee is the lead, and the other is the trail. The lead is positioned ahead of the play, even with the second-to-last defender to the extent possible, while the trail is positioned behind the play. Both are responsible for calling fouls and misconduct and determining the restart when the ball goes out of play on one of their assigned boundary lines. Since the lead is in a better position to determine offside, the lead is responsible for calling offside, while the trail provides an extra monitor for fouls and misconduct while the lead's attention is focused on offside. When the attack changes direction, the trail becomes the lead and vice versa.
The double dual system uses three referees all with whistlespositioned much as in the traditional diagonal system of control mandated by IFAB. Each referee has the same authority for decision making. It is authorized in the United States for college and high school matches although it is rarely used.

Association football, more commonly known as football or soccer, is a team sport played with a spherical ball between two teams of 11 players. It is played by approximately 250 million players in over 200 countries and dependencies, making it the world's most popular sport. The game is played on a rectangular field called a pitch with a goal at each end. The object of the game is to score by moving the ball beyond the goal line into the opposing goal.
Offside is one of the laws of association football, codified in Law 11 of the Laws of the Game. The law states that a player is in an offside position if any of their body parts, except the hands and arms, are in the opponents' half of the pitch, and closer to the opponents' goal line than both the ball and the second-last opponent.
Futsal is a variant of association football played on a hard court, smaller than a football pitch, and mainly indoors. It has similarities to five-a-side football.
An own goal is an event in competitive goal-scoring sports where a player scores on his or her own side of the playing area rather than the one defended by the opponent. Since own goals are often added to the opponent's score, they are often an embarrassing blunder for the scoring player, but in certain sports are occasionally done for strategic reasons.
A penalty kick is a method of restarting play in association football, in which a player is allowed to take a single shot on the goal while it is defended only by the opposing team's goalkeeper. It is awarded when a foul punishable by a direct free kick is committed by a player in their own penalty area. The shot is taken from the penalty mark, which is 11 m from the goal line and centred between the touch lines.
The Laws of the Game (LOTG) are the codified rules that help define association football. The laws mention the number of players a team should have, the game length, the size of the field and ball, the type and nature of fouls that referees may penalise, the frequently misinterpreted offside law, and many other laws that define the sport. During a match, it is the task of the referee to interpret and enforce the Laws of the Game.
A corner kick is the method of restarting play in a game of association football when the ball goes out of play over the goal line, without a goal being scored and having last been touched by a member of the defending team. The kick is taken from the corner of the field of play nearest to where it went out. Corners are considered to be a reasonable goal scoring opportunity for the attacking side, though not as much as a penalty kick or a direct free kick near the edge of the penalty area.
In various sports, a professional foul is a deliberate act of foul play intended to bring about an advantage for the perpetrator's team. Professional fouls are usually committed to prevent an opponent from scoring.
Instant replay or action replay is a video reproduction of something that recently occurred which was both shot and broadcast live. The video, having already been shown live, is replayed in order for viewers to see again and analyze what had just taken place. Some sports allow officiating calls to be overturned after the review of a play. Instant replay is most commonly used in sports, but is also used in other fields of live TV. While the first near-instant replay system was developed and used in Canada, the first instant replay was developed and deployed in the United States.
A football pitch is the playing surface for the game of association football. Its dimensions and markings are defined by Law 1 of the Laws of the Game, "The Field of Play". The pitch is typically made of natural turf or artificial turf, although amateur and recreational teams often play on dirt fields. Artificial surfaces must be green in colour.
A throw-in is a method of restarting play in a game of football when the ball has exited the side of the field of play. It is governed by Law 15 of The Laws Of The Game.
In the sport of association football, fouls and misconduct are acts committed by players which are deemed by the referee to be unfair and are subsequently penalised. An offence may be a foul, misconduct or both depending on the nature of the offence and the circumstances in which it occurs. Fouls and misconduct are addressed in Law 12 of the Laws of the Game.
Rugby union is a team sport played between two teams of fifteen players. It is known for its rich terminology.
In association football, an assistant referee is an official empowered with assisting the referee in enforcing the Laws of the Game during a match. Although assistants are not required under the Laws, at most organised levels of football the match officiating crew consists of the referee and at least two assistant referees. The responsibilities of the various assistant referees are listed in Law 6, "The Other Match Officials". In the current Laws the term "assistant referee" technically refers only to the two officials who generally patrol the touchlines, with the wider range of assistants to the referee given other titles.
In association football, goal-line technology is the use of electronic aid to determine if a goal has been scored or not. In detail, it is a method used to determine when the ball has completely crossed the goal line in between the goal-posts and underneath the crossbar with the assistance of electronic devices and at the same time assisting the referee in awarding a goal or not. The objective of goal-line technology (GLT) is not to replace the role of the officials, but rather to support them in their decision-making. The GLT must provide a clear indication as to whether the ball has fully crossed the line, and this information will serve to assist the referee in making his final decision.
Association football was first codified in 1863 in England, although games that involved the kicking of a ball were evident considerably earlier. A large number of football-related terms have since emerged to describe various aspects of the sport and its culture.
In games of association football teams compete to score the most goals during the match. A goal is scored when the ball passes completely over a goal line at each end of the field of play between two centrally positioned upright goal posts 24 feet (7.32 m) apart and underneath a horizontal crossbar at a height of 8 feet (2.44 m) — this frame is also referred to as a goal. Each team aims to score at one end of the pitch, while preventing their opponents from scoring at the other. Nets are usually attached to the goal frame to catch goalscoring balls, but the ball is not required to touch the net.
The video assistant referee (VAR) is a match official in association football who reviews decisions made by the head referee.
Futsal began in the 1930s in South America as a version of association football, taking elements of its parent game into an indoor format so players could still play during inclement weather. Over the years, both sports have developed, creating a situation where the two sports share common traits while also hosting various differences.
A free kick is a method of restarting play in association football. It is awarded after an infringement of the laws by the opposing team.
