The NFHS 2007 Casebook was extremely helpful to me for this problem. I have written a "procedure" that I have given to the head coach. I recommended he send that to each head coach of a team that will compete on our home track. That way they will know ahead of time what to expect. Per NFHS rule 7.2.7, the games committee has the right to establish the time allotted to be excused for an event. Based on several of the cases in the casebook where they indicated the person was gone for 15 minutes, and they described the situation as the athlete not returning in the alloted time, I conclude they consider 10-15 minutes reasonable time.
There was one entry I thought was very useful. I have quoted it below.
Guidelines for a competitor who has been excused from a field event to compete in another event include:
a. The competitor must receive permission from the event judge.
b. The judge must record the time excused.
c. The judge may allow the competitor to take a trial out of turn before being excused.
d. The judge will use some judgment in extending the time excused under
special circumstances, e.g., 3200-meter run.
e. In the high jump and pole vault, if the competitor has failed to return in
the allotted time and all other remaining competitors have either
passed, failed or cleared the existing height, the crossbar will be raised
to the next height and the judge will automatically pass the excused
competitor to the new height.
f. Coaches must take into account the limited time allowed to compete in
another event when determining the events any individual competitor
enters.
g. When an unusual circumstance, injury, reruns, etc., occurs that will
prolong the absence of the excused participant, it shall be the competitor's
responsibility to communicate this to the event judge.
Thanks to everyone's inputs and suggestions.
