Law Information

AYSO games follow FIFA (international soccer) Law very closely, with only a few changes to adapt to AYSO's philosophy (e.g. controlled substitution to ensure that "everyone plays") and, at the youngest age levels, to adapt the game to the physical and mental maturity of the players.  All AYSO referees should have a copy of the current AYSO edition of The Laws of the Game, which contains both the FIFA Laws and AYSO's modifications to them.  The Region 26 Referee's Handbook also contains most of this material.

Changes to the Laws of the Game

In 1997, FIFA completely revised and rewrote the text of The Laws of the Game, for the first time since 1938.  This year, thankfully, the changes were much more modest.

The official AYSO Summary of this year's changes by Bill Mason and the USSF Memorandum which covers this year's changes (found in the Referee section of the USSF web pages) are now available.

The official text of the Laws of the Game is available on-line from FIFA in PDF format, so you will need to download Adobe Acrobat to view them.

A chronological list of the changes to The Laws over the years, including the 1997 rewrite, can also be found at FIFA as History of Laws of the Game

"Advice"

The Laws of the Game are very terse.  They assume a general knowledge of how the game is played and they do not delve in depth into obscure cases. For many years, the additional Law material that addressed these cases was scattered and often quite hard to find (c.f. The Diagonal article Beyond The Laws of the Game); some was printed in the back of old (pre 1997) Law books.  Today, there are several important documents that draw this material together for the referee.

The first is AYSO's Interpretations, Instructions and Advice for Referees.  This booklet covers mainly the material from the back of the old Law books and some additional AYSO guidance.  It is available from AYSO directly (but only in hardcopy) and is distributed to all Palo Alto AYSO referees at clinics.

The second source is USSF's 2001 edition of Advice to Referees on The Laws of the Game which is available as a .pdf file, and in hardcopy from USSF.  Despite the similarity in names, this is a much more comprehensive document, designed to gather together nearly all of FIFA and USSF's supplementary guidance in one place. As such, it is an essential reference for the advanced referee.

The third source is the updated 2000 version of FIFA's Questions and Answers to the Laws of the Game.  This publication gives answers to questions frequently asked about each of the Laws.

AYSO Rules of Competition

Most of AYSO's Rules of Competition and modifications to the Laws are printed into the AYSO edition of The Laws of the Game (and are also included in the Region 26 Referee's Handbook).  The full text of AYSO's Rules and Regulations and Policy Statements from which these come can be found, along with other official AYSO documents, at AYSO's Rules, Policies, and Guidelines page.  Some of these are in PDF format, so you will need Adobe Acrobat to view them.

Age Differences

Players 9 and older (in the U10 division and above) use the full FIFA Laws (although U10 children play on 7 player teams on reduced size fields).  Under-7 and Under 8 teams play on an even smaller field, with a simplified set of Laws for the Younger Divisions.  Under-7 and Under-8 teams are made up of 4 players;  Under-9 teams are made up of 5 players.  Under 6 games are not formally officiated at all; instead they are "facilitated" by their team coaches.

Under-11 and above games are run using the "diagonal" system (center referee plus two assistant referees) with neutral center referees. A parent may be an assistant referee in his or her child's game. Under-10 games are also officiated using the diagonal system, with parent referees, using either a three referee or two referee team (plus one "club linesman"), depending on the number of referees available. In U11 and U12 there are 9 players on a side; in u14 and up there are 11.   Under-7 through Under-9 games are officiated by a single parent referee from one of the two teams.   More information on referee assignment in the various age brackets can be found in the referee FAQ's .

Substitution Rules for Under-19 and Under-16 Games

Unlike many youth soccer leagues, AYSO limits substitutions to make it practical for the referee to ensure that "everyone plays" at least half the game.  Substitutions are therefore only allowed at half time and at two "substitution breaks" midway through each half.  However, in Under-19 and Under-16 games, "free" substitutions are allowed in the fourth "quarter," provided that the players involved have already played at least half the game.  Details of the rules governing free substitutions can be found here and in the Region 26 Referee's Handbook. 

Player "Passes" for Under 19 and Under 16 Games

For inter-regional play in U16's and U19's, Area 2A does not require the use of player ID cards.

Under 10 Rules

The full Laws are used for Under-10 games, with two changes. First, the U10 Divisions use fields which are reduced in size.  Second, U10 teams consist of 7 players, rather than the full-sized teams of 11 used in the older divisions.

Also, each U10 team is required to provide a certified Regional referee for each game for which they are the home team. For more details, please see Under 10 Rules

Under-7, Under-8 and Under-9 Laws for Region 26

Most AYSO regions adapt the Laws significantly for U7-U9 players.  Unfortunately, such ad hoc changes can leave players, coaches and parents without a single reference source as to what the rules actually are. Palo Alto publishes a self contained set of Laws of the Game for the Younger Divisions for use in this Region.  They can also be found in the Region 26 Referee's Handbook and are distributed to U7-U9 coaches and referees at the start of each season.

Player Equipment

Both The Laws of the Game and the AYSO Rules of Competition prohibit players from wearing anything that, in the opinion of the referee, may be dangerous to either themselves or another player.  Because disputes about the danger of specific items keep arising, Region 26 has issued a list of prohibited items.  Items not on this list may also, of course, be deemed dangerous by the referee on the field.
