Improving Concussion Data

August 18, 2017

The Michigan High School Athletic Association’s 750 member high schools reported nearly 500 fewer concussions for the 2016-17 school year than the year before – 11 percent fewer.

That’s good news, but it’s not a trend we can bank on. It’s too soon to do that. There are too many variables that might explain or contribute to the decline from 4,452 to 3,958 concussions.

But of this we are certain: Schools are taking head injuries seriously. It is not a lack of concern or a lack of care in reporting that has led to the 11 percent decline.

It’s more likely the second year’s data is just better than the first year. The process was better understood. The numbers are more accurate.

Our data will become most reliable and useful when we have several years to compare and analyze. Only then will we really know where the trouble spots remain; and only then can those areas be most effectively addressed.

Classes or Divisions

April 4, 2014

Never is the continuous cycle of school sports more obvious to me than at this time of year. Just as winter tournaments conclude for 2013-14, we post the classifications and divisions for MHSAA tournaments in 2014-15.
Unlike many states which reclassify every two, three or four years, we collect enrollment figures each year and redraw the lines between Classes A, B, C and D each year in late March. And for all sports except basketball and volleyball, we place an almost equal number of schools that actually sponsor the sport into equal divisions – usually four divisions, but fewer for sports that are sponsored by a relatively small number of schools.
This traditional treatment of boys and girls basketball and girls volleyball – continuing with four classes rather than four divisions with an equal number of schools that actually sponsor the sport in each division – reflects that when last considered for change 17 years ago, there wasn’t much difference in the number of schools in the four classes vs. the four equal divisions in these three tournaments.
For 2014-15, of the 749 MHSAA member schools, 724 indicate they sponsor boys basketball, 716 sponsor girls basketball and 704 sponsor girls volleyball. (Among the sports in equal divisions, the most populous is baseball with 630 sponsoring schools.)

Last January, the MHSAA Classification Committee requested that staff provide the Representative Council what the numbers would look like for 2014-15 if these three sports were in “equal divisions” like other sports. The Classification Committee wasn’t recommending any change – just asking that the Representative Council see the numbers again.

  • In boys basketball, the number of schools in Divisions 1, 2, 3 and 4 would be 181, compared to 188, 182, 182 and 172 in Classes A, B, C and D, respectively.
  • In girls basketball, the number of schools in Divisions 1, 2, 3 and 4 would be approximately 179, compared to 186, 181, 182 and 167 in Classes A, B, C and D, respectively.
  • In girls volleyball, the number of schools in Divisions 1, 2, 3 and 4 would be approximately 176, compared to 186, 178, 180 and 160 in Classes A, B, C and D.

Obviously, every time more schools are placed in a division, the enrollment range between the largest and smallest school of that division expands. Therefore, a change to equal divisions places more schools and expands the enrollment range in the division of schools where enrollment spreads have the greatest impact - Division 4. It was our smallest schools that least liked the change to equal divisions in other sports 17 years ago. They would be the dissenters to this change for basketball and volleyball today.
