ITF competitors wear a distinctive dobok that differs visually from the WT uniform. The ITF dobok features a cross-over (overlap) front top, secured by a tie on the right side, in contrast to the V-neck pullover top used in WT competitions.

The ITF belt ranking system progresses through the following colors: White (10th Gup — signifying innocence), Yellow (8th–9th Gup — the earth from which the plant grows), Green (6th–7th Gup — the growing plant), Blue (4th–5th Gup — the sky toward ...

ITF sparring does not use the electronic trunk protector (hogu) or electronic headgear employed in WT competition.

Power breaking events use standardized wooden boards, typically pine or paulownia, of regulated thickness (approximately 2.5 cm per board for adults). Spacers may be used to separate stacked boards.

Special technique events require height-adjustable targets — typically small padded boards or breakable targets suspended at measured heights above the ground. For distance events, a horizontal obstacle (such as a vaulting box or rope) is placed a...

The ITF sparring competition area is a square mat measuring 9 meters × 9 meters, clearly demarcated by boundary lines. This differs from the octagonal competition area used in WT events.

A safety zone of at least 2 meters must surround the competition area on all sides, free from any obstacles, equipment, or spectators. The total required floor space is therefore a minimum of 13 meters × 13 meters.

Starting positions for the two competitors are marked at the center of the ring, approximately 1.5 meters apart, facing each other. The competitor designated as "blue" (chong) stands to the referee's right, and the competitor designated as "red" (hong) stands to the referee's left.

The center referee operates within the competition area. Four corner judges are seated at the four corners of the ring, each equipped with scoring devices (flags, clickers, or electronic input pads depending on the tournament).

Pattern competitions require a flat, unobstructed area of at least 10 meters × 10 meters, covered with appropriate matting. Breaking and special technique events require additional clearance for run-up space (minimum 5 meters) and overhead clearance of at least 4 meters for jumping techniques.
