The high jump and pole vault do not measure each attempt. The bar is set at announced heights, and competitors choose which of those heights to attempt.
How the progression is decided
Officials publish a schedule of heights before the competition, rising by fixed amounts. Increments are usually larger early and smaller as the field thins.
Every competitor faces the same bar height at the same point, which makes direct comparison straightforward. There is no measurement of a clearance beyond pass or fail.
Once only one athlete remains, that competitor may request further heights in any increment above the last cleared bar. The schedule becomes discretionary at the end of the competition.
Why passing a height is a real decision
Each athlete has three attempts at any height and is eliminated after three consecutive failures. Passing preserves attempts for a higher bar.
Skipping a height risks entering the next one without a successful jump in the sequence, which affects rhythm and confidence. Timing matters technically.
Passing also affects tie-breaking, since fewer failures at earlier heights improves standing. The decision is simultaneously tactical and technical.
How ties are resolved
Athletes clearing the same maximum height are separated by the number of attempts taken at that height, so a first-time clearance beats a third-attempt one. Fewer failures at the decisive bar wins.
If that fails to separate them, total failures across the whole competition are counted. Clean early jumping therefore carries value beyond confidence.
Where a tie persists for first place, a jump-off may be used with the bar moved up and down. The format is unique among athletics events.
Why energy management shapes the contest
Jumping is explosive and taxing, and a long competition may extend over hours. Each attempt consumes capacity that cannot be recovered within the event.
Athletes therefore enter at a height high enough to conserve attempts but low enough to establish rhythm. Entry height is a considered choice.
Weather and delays complicate this further, since staying warm across a long gap is demanding. Physical preparation continues throughout the competition.
What the format produces for spectators
Because everyone attempts the same bar, the state of the competition is immediately legible. No calculation is needed to know who leads.
The rising bar also creates a natural narrative, with the field reducing visibly as heights increase. Tension builds structurally rather than by chance.
The final rounds often involve a single athlete against a bar, which is unusual in a stadium sport. The format isolates the competitor deliberately.
