January 17, 2002

To: CIF Section Commissioners, Administrators, Track and Field Coaches, and Officials

From: Hal Harkness, CIF Rules Interpreter for Track and Field/Cross Country

Subject: Summary of NFHS Rules Interpreters Meeting, January 15, 2002
 

RULE CHANGES
Rule 4-3-7, 9-5-7 (New) Contestants shall not wear jewelry with the exception of religious or medical medals. If such medals are worn, they shall be taped to the body under the uniform. Rationale: This rule will enhance safety issues and bring track and field/cross country in line with other NFHS rule codes. Approximately 50% of our state associations have enforced a no jewelry rule, and this change will make all state consistent regarding this issue.

Note: Initially, this will be the most controversial of this year’s rule changes. It is sweeping in scope. Athletes while competitors (after reporting to the starting line or field event judge) are forbidden to wear all forms of visible jewelry including bracelets, regardless of material, metal pins/clips or hard plastic barrettes in their hair, rings, earrings or studs, and any type of body piercing. Remember, the operative word here is visible.

However, if a competitor competes with something that is illegal that becomes visible.

during the course of his/her event, he/she can be disqualified from that event

Wrist watches are exempt from this rule, they are considered to be equipment.

Taping over pieces of jewelry is not to be allowed. Jewelry is to be removed completely or an athlete shall not be allowed to compete. The fact that an item cannot be removed or ears were just pierced is not to be considered as an acceptable excuse for compliance.

A medical alert bracelet is permitted if taped to the wrist with the faceplate showing..

Religious medals must be removed from around the neck and taped to the body under the jersey.

Beads tightly woven into hair are allowed, but beads dangling from strands of hair are not.

The penalty for competing while wearing prohibited jewelry is event disqualification.

Rule 4-6-1 (New) For the purposes of determining whether an athlete is a contestant or competitor, a running event or heat begins when the contestants report to the starting line (and become competitors), and is considered to be official and concluded when the places have been determined and the results of been recorded at the finish line.

Rule 4-6-2 (New) A field event is considered official and concluded when the places have been determined and the field event judge has recorded the results.

Rationale: This change will aid the referee and determine the appropriate penalty when a violation occurs prior to or after the conclusion of a running or field event. Rule 7-2-5 (Change) A competitor shall initiate a trial that is carried to completion in one and one half minutes (1:30) in the pole vault and one minute (1:00) in all other jumping events. Note: Since an inconsistency was created between time limits for throwing and jumping events, California will apply the same time standards for all field events for 2002.


EDITORIAL CHANGES
 

Rule 4-3-1b (Change) Any visible shirt(s) worn under the jersey and all visible apparel worn under the shorts must be unadorned and of a single (and same) color.

Note: This does not change our existing rule, it only applies if an athlete were to wear two layers of clothing under his/her short or jersey. If more than one layer is worn, all must be the same color. Apparel visible under the jersey need not be the same, single color as apparel visible under the shorts.
 
Rule 4-3-2 (Add)Bare midriff tops are not acceptable. The jersey (singlet) must hang below or be tucked into the waistband of the shorts or briefs when the competitor is standing erect. Note: The intent of the rule is to insure that jerseys cover the midriff completely when a competitor is standing fully erect before beginning competition.

However, The Games Committee (State Track and Field/Cross Country Advisory Committee) has determined that all jerseys must be tucked into the short prior to competition and the waistband of the shorts shall not be rolled down.

Rule 4-3-3, 9-5-3 (Change) The shoe upper must be designed so that it can be fastened securely to the foot.

Rule 9-5-5 (Add) A competitor shall wear the same assigned unaltered contestant number when numbers are used.
