2018-19 Concussion Data Reinforces Trends
September 26, 2019

Data on student-athlete concussions collected by the Michigan High School Athletic Association from member high schools during the 2018-19 school year further reinforced findings from the first three years of reporting, and will contribute significantly as a number of MHSAA-associated groups work during the coming year to reduce the incidence of those injuries.
The 2018-19 concussion report found student-athletes at MHSAA member high schools encountered a total of 3,686 head injuries during the past school year – 3.0 percent more than in 2017-18. But that slight increase barely affected two key ratios. The number of injuries per member school was 4.9, up just a tenth of a percent from 2017-18, and for the second straight year only 1.3 percent of participants in MHSAA sports experienced a head injury, still down from 1.4 in 2016-17 and 1.6 percent the first year of the study. Total participation in MHSAA sports for 2018-19 was 281,992 – with students counted once for each sport they played.
The MHSAA has continued to invite Michigan’s universities, health care systems and the National Federation of State High School Associations (NFHS) to take part in analyzing the data and resulting questions that have arisen during the past three years. The 2018-19 results will be examined by the MHSAA’s newly-formed Sports Medicine Advisory Committee and also undergo analysis by representatives of Michigan State University’s Institute for the Study of Youth Sports. Furthermore, the MHSAA is directing its sport committees to study the data as they consider adjustments that could be made to rules for practice and competition.
“The 2018-19 concussion survey further reinforced the findings and trends we have seen emerge; not only in specific sports, but across all of our activities – and this latest set of results also raises new questions,” MHSAA Executive Director Mark Uyl said. “We must continue to look at how changes to playing rules and improvements in equipment may be beneficial moving forward, and also how we can further educate administrators, coaches, athletes and parents to identify and provide treatment for these injuries as soon as possible. We also are excited for the opportunity to have more eyes on these results as we continue to explore more ways to make our games safer.”
As first mandated in 2015-16, member schools are required to report head injuries to the MHSAA identifying the sport that each student-athlete was participating in and whether the injury was sustained during practice or competition. Schools also are required to designate at which level – varsity, junior varsity or freshman – the injury occurred.
The full report of all head injuries experienced during 2018-19 by student-athletes at MHSAA member high schools – including percentages by sport (per 1,000 participants), gender and team level, as well as data tracking when athletes returned to play – is available on the Health & Safety page of the MHSAA Website.
Keeping with the first three years of this survey, the MHSAA continued to receive data from more than 99 percent of its member high schools after the fall, winter and spring seasons. Member junior high and middle schools also were allowed, although not mandated, to report their head injuries; and those findings are not part of the published report.
Boys in 2018-19 experienced 2,404 – or 65 percent – of concussion injuries, just a percent less than during 2017-18, and not surprisingly as boys have a much higher participation in contact sports. More than half of head injuries – 59 percent – were experienced by varsity athletes, a slight increase of three percent from the previous year. A total of 2,441 head injuries – or 66 percent – came in competition as opposed to practice. Just more than half took place during either the middle of practice or middle of competition as opposed to the start or end, and 51 percent of injuries were a result of person-to-person contact.
The MHSAA also asked schools to report the number of days between the head injury and the athlete’s return to activity – and the two largest groups returned to activity after either 6 to 10 days of rest (24 percent) or 11 to 15 days (23 percent). All of these findings were within 1-3 percent of those discovered from the 2017-18 data.
Contact sports again revealed the most head injuries. Ranking first was football, 11 and 8-player combined, with 44 head injuries per 1,000 participants – an increase of three per 1,000 from 2017-18 but the same ratio as 2016-17 and still down from 49 head injuries per 1,000 football participants shown by the first study in 2015-16. Ice hockey again revealed the second-most injuries per 1,000, with 35 (also up three from a year ago but still down from 36 injuries per 1,000 from 2016-17 and 38 per 1,000 in 2015-16), and girls soccer was third with 25 head injuries per 1,000 participants for the second year in a row. Wrestling followed with 22 head injuries per 1,000 participants.
Continuing a noticeable trend of the last few years, the next three sports to show the highest incidences of head injuries were girls sports – girls lacrosse, competitive cheer and basketball also revealed 20 per 1,000 participants, although basketball was down two injuries per 1,000 participants or nearly 10 percent from the previous year. Boys lacrosse (16), boys soccer (14), girls volleyball (11), softball (11) and gymnastics (10) also showed double-digit head injuries per 1,000 participants.
Females again reported significantly more concussions than males playing the same or similar sports – soccer, basketball and baseball/softball. Female soccer players reported nearly double the concussions per 1,000 participants as male soccer players (25 to 14), while female basketball players reported nearly triple the number of concussions per 1,000 participants (20 to 7). Softball players also reported nearly triple the concussions per 1,000 participants of baseball players (11 to 4).
Schools report possible concussions online via the MHSAA Website. Reports are then examined by members of the MHSAA staff, who follow up with school administrators as those student-athletes continue to receive care and eventually return to play. Student privacy is protected.
The reporting of concussions is part of a three-pronged advance by the MHSAA in concussion care begun during the 2015-16 school year. The MHSAA completed in spring 2017 the largest-ever state high school association sideline concussion testing pilot program, with a sample of schools from across the state over two years using one of two screening tests designed to detect concussions. The MHSAA also was the first state association to provide all participants at every member high school and junior high/middle school with insurance intended to pay accident medical expense benefits – covering deductibles and co-pays left unpaid by other policies – resulting from head injuries sustained during school practices or competitions and at no cost to either schools or families.
Previously, the MHSAA also was among the first state associations to adopt a return-to-play protocol that keeps an athlete out of activity until at least the next day after a suspected concussion, and allows that athlete to return to play only after he or she has been cleared unconditionally for activity by a doctor (M.D. or D.O.), physician’s assistant or nurse practitioner.
In addition, the MHSAA’s Coaches Advancement Program – which includes courses that must be completed by all varsity head coaches hired for the first time at a member school – provides substantial instruction on concussion care. Separately, rules meetings that are required viewing for high school varsity and subvarsity head and assistant coaches at the start of each season include detailed training on caring for athletes with possible head injuries.

2020-21 Classifications Announced
April 20, 2020
By Geoff Kimmerly
Second Half editor
Classifications for MHSAA elections and postseason tournaments for the 2020-21 school year have been announced – including football divisions determined preseason for the first time since 1998 – and with enrollment breaks for postseason tournaments posted to each sport’s page on the MHSAA Website.
Classifications for the upcoming school year are based on a second semester count date, which for MHSAA purposes was Feb. 12. The enrollment figure submitted for athletic classification purposes may be different from the count submitted for school aid purposes, as it does not include students ineligible for athletic competition because they reached their 19th birthday prior to September 1 of the current school year and will not include alternative education students if none are allowed athletic eligibility by the local school district.
All sports’ tournaments are conducted with schools assigned to equal or nearly equal divisions, with lines dependent on how many schools participate in those respective sports.
For 2020-21, there are 752 tournament-qualified member schools. Schools recently were notified of their classification, and sport-by-sport divisions were posted to the MHSAA Website today (April 20). MHSAA Executive Director Mark Uyl said schools may not subsequently lower their enrollment figure. However, if revised enrollment figures are higher and indicate that a school should be playing in a higher division, that school would be moved up.
Football will undergo a significant classification change for the 2020 season, with teams in both 11 and 8-player assigned their divisions before the season for the first time since 1998; from 1999-2019, divisions for the 256-team 11-player field (and later the 8-player tournament) were determined after the regular season. A hard enrollment limit also will take effect this fall for teams to be eligible for the 8-player tournament – all schools with 215 or fewer students are eligible for the 8-player playoffs if they play that format during the regular season.
Two 11-player football champions will play in different divisions in 2020 than those they won a year ago. Grand Rapids Catholic Central will move to Division 5 after winning the Division 4 championship last season, while reigning Division 6 champion Monroe St. Mary Catholic Central will play in Division 7 this upcoming season. Also, 2019 Division 2 runner-up Detroit Martin Luther King will play in Division 3 this fall. In 8-player football, the reigning champions will trade divisions – 2019 Division 1 winner Colon moving into Division 2, and Division 2 champ Pickford moving into Division 1 for this fall.
A number of 2019-20 champions will be playing in different divisions in 2020-21. Grand Rapids Forest Hills Northern’s boys soccer team will move into Division 1 after winning the Division 2 title in 2019. The East Grand Rapids girls swimming & diving team will move back into Lower Peninsula Division 2 – which it won in 2017 – after earning the last two championships in Division 3. Bridgman’s girls cross country team will move into Lower Peninsula Division 3 after winning Division 4 last fall, and Grass Lake’s boys bowling team will move into Division 3 after winning the Division 4 title this winter. The Allegan boys tennis team will move into Lower Peninsula Division 3 after sharing the Division 4 title in the fall, while the Ishpeming Westwood girls tennis team will move into Upper Peninsula Division 1 after winning the Division 2 title the last four seasons. (NOTE: MHSAA Finals in five Winter sports and all Spring sports were canceled in 2019-20 due to COVID-19.)
Visit the respective sport pages on the MHSAA Website to review the divisional alignments for all MHSAA-sponsored tournament sports.
Traditional classes (A, B, C, D) – formerly used to establish tournament classifications – are used only for MHSAA elections. To determine traditional classifications, after all counts are submitted, tournament-qualified member schools are ranked according to enrollment and then split as closely into quarters as possible. For 2020-21, there are 188 member schools in each class.
Effective with the 2020-21 school year, schools with 831 or more students are in Class A. The enrollment limits for Class B are 392-830, Class C is 182-391, and schools with enrollments of 181 and fewer are Class D. The break between Classes A and B decreased 32 students from 2019-20, the break between Classes B and C decreased three students, and the break between Classes C and D is seven students fewer than the 2019-20 school year.

The MHSAA is a private, not-for-profit corporation of voluntary membership by more than 1,500 public and private senior high schools and junior high/middle schools which exists to develop common rules for athletic eligibility and competition. No government funds or tax dollars support the MHSAA, which was the first such association nationally to not accept membership dues or tournament entry fees from schools. Member schools which enforce these rules are permitted to participate in MHSAA tournaments, which attract more than 1.4 million spectators each year.
