Each gymnast is allowed only one
attempt on each apparatus, unless the attempt is interrupted through no
fault of the gymnast, except the women's vault.
In the women's vault, the athletes are allowed
two attempts, with the scores averaged.

There are no compulsory
routines. Each gymnast determines the make-up of his or her own routine,
but they must meet skill criteria relating to degree of difficulty.

Spotters are allowed to stand near the
horizontal bars, rings, parallel bars and vault. They are present to
help prevent accidents, but gymnasts are penalized 0.4 of a point if
they need help.

Gymnasts are allowed help into their starting
positions for the rings and horizontal bars.

Competitors are allowed to use bandages or
leather grips on their hands.

Coaching during routines is prohibited.

Gymnasts are not allowed to leave the arena
during competition without permission.

Unsporting behavior is penalized.

Dismounts should end with the feet together in
a standing position.

There are two panels of judges who rate each
performance. Two difficulty judges confer to give each routine a
difficulty rating out of 10, depending on the maneuvers it contains. Six
execution judges independently rate each performance for form and
execution.

They give each routine a mark out of ten,
deducting fractions of points for mistakes. Minor errors result in the
loss of 0.1 of a point, more serious errors cost the gymnast 0.2, 0.3 or
0.4 of a point.

A gymnast who falls off, or into, the apparatus
loses half a point.

The highest and lowest scores awarded by the
judges are discarded and the remaining four are averaged.

In all-around events the scores for each
competitor on each apparatus are added, giving a maximum score of 40 for
the women (10 points for each of four apparatus) and 60 for the men (10
points for each of six apparatus).

Each nation in the teams competition is
represented by six athletes. Five complete routines on each apparatus
with only the top four scores counting.
