The bar shall be set at the appropriate starting height for the age group/individual competing. Bar height is checked with the measuing stick perpendicular to the ground and at the lowest point of the bar; that is, the middle of the bar. The outer edges shall measure equal heights, and be set so that the centre of the bar is at the stipulated height.
Each competitor has three jumps, and may commence jumping at any height above the starting height. Athletes must take off from one foot. An athlete shall be eliminated from the event after three consecutive failures at a particular height, reglardless of the height. An athlete may achieve his/her second or third attempt at a particular height (after missing the first or first and second attempts) and still jump the next height. Three consecutive baulks constitute a failed jump.
