Raising Expectations for Managing Heat and Humidity

February 19, 2013

The MHSAA Representative Council is scheduled to vote on March 22, 2013, to approve a “Model Policy for Managing Heat and Humidity” that would appear in the 2013-14 MHSAA Handbook.

The policy, patterned after a mandatory policy of the Kentucky High School Athletic Association, requires that temperature and humidity readings be taken at the site of activities 30 minutes before the start of the practice or competition and again 60 minutes after the start of that activity.  The readings must be recorded in writing and kept in the files of school administration.  Inexpensive devices may be used that automatically calculate the “heat index.”

If the heat index is below 95 degrees, only normal precautions are required.  However, readings of 95 to 99 degrees and then 100 to 104 degrees require additional precautions; and all activity must be postponed or suspended if the heat index climbs above 104 degrees.

When the air temperature is below 80 degrees, there is no combination of heat and humidity that will result in need to curtail activity.

This is being proposed as a model policy for 2013-14.  The MHSAA will monitor school districts’ acceptance of this policy or adoption of similar policies before considering a mandate of this or similar policies.

The model policy will be mandatory for MHSAA tournaments. 

Competitive Classes

May 7, 2013

After the classifications and divisions for MHSAA tournaments in 2013-14 were posted on mhsaa.com last month, there were more questions and comments than in previous years.

Some of this results from electronic media – how quickly our information gets distributed far and wide, and how easy it is for people to email their opinions.  This isn’t bad.

But we were able to discern in the feedback that there is poor public understanding of school enrollment trends in Michigan.  For example, many people objected that the spread between the largest and smallest schools in the classifications and divisions has grown too large.

In fact, taking the long view, the difference between the largest and smallest schools has been shrinking:

  • In Class D, the difference between the largest and smallest school has trended downward over the past 25 years, and will be approximately 20 percent smaller for 2013-14 than in 1989 (to 189 from 247).
  • The same is true in Class C, although less dramatically (to 221 from 259).
  • The same is true in Classes B and A, although less consistently (from 496 to 464 in Class B; and from 2,111 to 1,888 in Class A).

If there is need for more than four classes in basketball or girls volleyball, or for more than four “equal divisions” in most other sports, it is not because of the reason most often cited.  That reason – that the enrollment spread is growing too large – is not supported by the facts.
