Following are some of the important rules of high jump set by International Association of Athletic Federation (IAAF)
Take-off must be made with one foot only.
Dislodging of the bar or breaking the plane near the edge of the bar before clearing will not be counted as successful jump.
Jumping height is decided by the Chief Judge. Players can accept the challenge or may pass it.
If the competitor fails to jump the required height in three consecutive attempts then he/she will be disqualified from the competition.
During the final match, whoever clears above the bar with highest height is declared as winner.
In case there is a tie, following two conditions may be applied to decide the winner.
The player who has fewer misses at the height at which the tie has occurred, is declared as winner.
The player who has fewest misses in the overall tournament is declared as winner.
The jumpers have to face a jump-off if there will be a tie for a first place.
The height will be greater than the previous level. Each player will be given one chance for each clearance
