For both the shot put and discus throw events, it is a foul if the competitor, after stepping into the circle, fails to pause before starting the throw.

A stopboard is required for both the shot put and discus events.

In the throwing events, the event judge marking where the implement lands stands outside the landing sector, holding one end of the measuring tape, until the thrower releases the implement.

The minimum weight for the Track implements are as follows:
High School Boys Discus: 1.6 kilogram (kg)
High School Girls Discus: 1.0 kg
7th & 8th Grade Boys Discus: 1.0 kg
7th & 8th Grade Girls Discus 1.0 kg
High School Boys Shot Put: 12 lbs
High School Girls Shot Put: 4 kg
7th & 8th Grade Boys Shot Put: 4 kg
7th & 8th Grade Girls Shot Put: 6 lb

The head event judge may change the order of competition by any method in the preliminaries and finals to accommodate those who may be excused to participate in other events.

The angle of the throwing sectors (in degrees) for the shot put and discus events is the same.

Thrower A makes a mighty throw but loses his balance and stumbles out of the back half of the ring a split second after the implement lands in the sector. This is a foul throw because he must leave the ring with his body totally under control.

After executing a fair throw but before the official has ruled it fair or foul, Shot Putter A stops and taps his foot on top of the toe board before exiting through the back half of the ring. This is a foul.

Thrower A, after entering the circle and before beginning his throw, accidentally drops his implement. He stops, picks up the implement, pauses within the circle, and then begins his throwing motion. This is fair throw to this point and he should be allowed to continue his attempt.

The measurement standard for recording length of discus throws and shot puts is the same: i.e., the measurement should be recorded to the nearest lesser inch or centimeter.

The head event judge may choose to permit a competitor to take preliminary and final trials in succession to accommodate those who may be excused to participate in other events.

The head event judge may change the order of competition by any method in the preliminaries and finals to accommodate those who may be excused to participate in other events.

The head event judge is responsible for training the other event judges working the event and to ensure they accurately perform their duties.

The head event judge oversees the inspection of the implements and sees that the field event starts on time and continues without delay.

Lines 2 inches wide and 8 inches long, lying on the diameter extended and outside the circumference of the ring, should be used to designate the back half of both the shot put and discus throwing circles.

The measurements of both the shot put and discus throws are made from the nearest edge of the first mark made by the implement to the inside edge of the throwing circle nearest such mark. To achieve this, the measuring tape is held at one end by an event judge at the nearest edge of the first mark made by the implement and at the other end by an event judge holding the tape so that it crosses the center of the circle. The head event judge records the distance where the tape crosses the inside edge of the throwing circle.

The diameters of the high school throwing circles are as follows:
Boys & Girls Discus: 2.50 meters (8 feet, 2.5 inches)
Boys & Girls Shot Put: 7 feet

The head event judge should immediately indicate a fair or foul attempt as soon as the attempt has landed and the competitor’s body is under control and not wait until the competitor has left the throwing circle.

The head event judge determines if an attempt is fair or foul. He indicates a fair decision by raising a white flag and/or clearly announcing “fair.” He indicates a foul attempt by raising a red flag and/or clearly announcing “foul.”

When making an attempt in the shot put or discus events, the implement (shot or discus) that lands on any part of the sector lines in considered in and thus, a fair throw.

Thrower A performs her attempt in the shot put by doing a body-weight squat launching the shot out and upward by swinging the arms powerfully in an underhanded motion. This is a fair throw.

The head event judge is responsible for judging each attempt and measuring each fair attempt.

For both the shot put and discus throw events, it is a foul if the competitor, after taking a position within the throwing circle and after initiating a throwing motion, touches any surface outside the circle during the throw. (Exception: it is not a foul for a shot putter to touch the inside of the stopboard)

The sector for the shot put & discus throw can be marked as follows from the center of the circle. An isosceles triangle with two equal sides (edges of the sector) 1 and 2/3 x the length of a straight line between the two.

The head event judge is responsible for checking and certifying the event results, indicating the place winners, before submitting them to the scorer.
