MHSAA Announces 2015-16 Concussion Data

September 12, 2016

The Michigan High School Athletic Association has completed an unprecedented yearlong collection of head injury reports from its member schools, mandated in 2015-16 for the first time as part of an effort to identify and reduce the incidence of those types of injuries in educational athletics.

The MHSAA requested that member schools report, by sport, possible concussions by their student-athletes during both practice and competition. Reporting for the 2016-17 school year is underway, and schools again are required to designate if potential concussions occurred during competition or practice and at which level – varsity, junior varsity or freshman.

The full report of all head injuries experienced during 2015-16 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.

The MHSAA received data from more than 99 percent of its member high schools after the end of the fall, winter and spring seasons, and continued to track each injury report through its conclusion this summer. Member junior high and middle schools also were allowed, although not mandated, to report their potential head injuries; those findings are not part of the published report.

It is the hope that universities, health care systems and the National Federation of State High School Associations will take part in analyzing the data. The MHSAA will work, in particular, with Michigan State University’s Institute for the Study of Youth Sports to explore these findings and their relation to possible changes and additions in coaches education.

“We know that school sports are safer than they’ve ever been, thanks to advances in equipment, increased and more complete coaches education and rules designed to bring higher levels of safety to both practices and competition,” said John E. “Jack” Roberts, executive director of the MHSAA. “However, this unprecedented effort will allow us for the first time to set a baseline by which we can determine year-to-year progress as we work to reduce the incidence of head injuries in school sports, while providing questions we will seek to answer with assistance from our research partners.”

Student-athletes at MHSAA member high schools encountered during 2015-16 a total of 4,452 head injuries – or 5.9 per member school. Total participation in MHSAA sports for 2015-16 was 284,227 – with students counted once for each sport he or she played – and only 1.6 percent of participants experienced a head injury. Boys experienced 3,003 – or 67 percent – of those injuries, although boys participation in sports, especially contact sports, also was higher than girls.

More than half of head injuries – 54 percent – were experienced by varsity athletes. A total of 2,973 – or 67 percent – came in competition as opposed to practice. More than half took place during either the middle of practice or middle of competition as opposed to the start or end, and nearly 56 percent of injuries were a result of person-to-person contact. The largest percentage of athletes – 28 percent – returned to activity after 6 to 10 days, while 20 percent of those who suffered head injuries returned after 11-15 days of rest.

Not surprisingly, contact sports revealed the most head injuries. Ranking first was 11-player football with 49 head injuries per 1,000 participants, followed by ice hockey with 38 and 8-player football with 34. However, girls soccer was just behind with 30 injuries per 1,000 participants, and girls basketball ranked fifth with 29 injuries per 1,000.

A startling disparity in the number of reported head injuries suffered by girls and boys playing the same sports was the most significant finding revealed by the concussion reporting. Soccer, basketball and baseball/softball are played under identical or nearly identical rules, and in those sports females reported significantly more concussions than males playing the same or similar sport.

Female soccer players reported 30 concussions per 1,000 participants. Male soccer players, meanwhile, reported only 18 concussions per 1,000 participants. Female basketball players reported 29 concussions per 1,000 participants; male players reported 11. Softball players reported 11 concussions per 1,000 participants, and baseball players reported four per 1,000.

“Experts tell us that it’s not surprising that girls report more head injuries than boys. But we found it stunning how many more head injuries were reported for girls than boys,” Roberts said. “As we delve deeper into the data, we hope to identify what physiological, social and psychological factors may contribute to this disparity – and how we can better prepare school personnel and especially coaches to watch for over- or under-reporting.”

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 possible concussions is part of a three-pronged advance by the MHSAA in concussion care begun during the 2015-16 school year which is producing data related to the frequency and severity of head injuries. The MHSAA in fall 2015 launched the largest-ever state high school association sideline concussion testing pilot program, with 62 schools taking part by using one of two screening tests designed to detect concussions. One of the objectives of the pilot was to increase awareness of concussions and improve sideline detection, and results indicated that the average number of possible concussions reported by pilot schools exceeded the average reported by schools outside the pilot group. For the 2016-17 school year, 34 schools are taking part in one of the two pilot programs as the project was concentrated to include schools which were diverse in size and location and able to best conduct the pilots to completion. The pilots will focus on sports for which most concussions occur, according to the mandated reporting by all schools during the 2015-16 school year.

The MHSAA also is 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. During 2015-16, a total of 159 claims were made – with more than half coming in football (55) or girls basketball (29).

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.

The MHSAA is a private, not-for-profit corporation of voluntary membership by more than 1,400 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.

More than two decades have passed since Alisha Glass took her final swing at a volleyball in a Leland High School uniform, and yet her accomplishments for her small-town school in Northern Michigan remain among the most notable in that sport’s history not just statewide, but at the national level.

Glass, now Alisha Glass Childress – who went on to star on three Penn State national championship teams and help the U.S. national team to a bronze medal at the 2016 Olympics – will have her record-setting high school career enshrined this summer as one of 12 honorees announced today as this year’s inductees into the National High School Hall of Fame by the National Federation of State High School Associations (NFHS).

Alisha Glass Childress headshotChildress will be inducted as part of the 43rd Hall of Fame class at a ceremony during the NFHS summer meeting June 29 in Salt Lake City. The rest of the class is made up of four more athletes, three coaches, two game officials, one former state association administrator and one former fine arts educator. Childress was nominated  by the Michigan High School Athletic Association.

She will become the Hall of Fame’s 11th inductee from Michigan, joining the MHSAA’s first full-time Executive Director Charles E. Forsythe (inducted 1983), River Rouge boys basketball coach Lofton Greene (1986), Warren Regina athletic director, softball and basketball coach Diane Laffey (2000), Fennville basketball and baseball standout Richie Jordan (2001), Grosse Pointe Woods University Liggett boys and girls tennis coach Bob Wood (2005), Bloomfield Hills Cranbrook hockey standout Jim Johnson (2007), Owosso football, basketball and baseball all-stater Brad Van Pelt (2011); Vermontville Maple Valley baseball national record holder Ken Beardslee (2016), retired MHSAA Executive Director John E. “Jack” Roberts (2022) and Dearborn Heights Robichaud football, basketball and track & field star Tyrone Wheatley (2024).

“My high school career at Leland, surrounded by such an amazing support system and community, was the essential first chapter of my story. It cultivated the grit and the fundamental love for the game that allowed me to reach the highest levels of athletics,” Childress said. “I’m proud of every medal and trophy, but I’m just as proud of the roots I planted back in high school that made them all possible.”

Childress graduated from Leland in 2006 with national high school career records of 3,584 kills, 680 blocks and 937 aces, and 296 aces for one season as a junior. Her aces records still stand, her career kills record stood until broken in 2024 by Shelby’s Navea Gauthier, and she remains third on the career blocks list. Glass continues to hold MHSAA records for single-season and career aces and also for her 48 kills in Leland’s 2005-06 Class D Final win over Battle Creek St. Philip. Childress also led Leland to a Class D runner-up finish in 2004-05 and the Semifinals in 2003-04. (All three tournament runs took place while girls volleyball was still played during the winter season before moving to the fall to begin the 2007-08 school year).

Childress earned the Miss Volleyball Award and Gatorade Player of the Year Award for Michigan as a senior, and her name is listed 19 times throughout the MHSAA girls volleyball record book. She also made Michigan's Class D all-state first team on the basketball court as both a junior and senior, averaging 18 points and 11 rebounds per game as a junior and 16 points, 10 rebounds and 3.7 blocked shots per game as a senior while leading her basketball team to Class D Quarterfinals both of those seasons.

“As our staff researched our first 50 years of female sports for our ‘Title IX at 50’ celebration during the 2021-22 school year, they told stories of several standouts who went on to collegiate, Olympic and professional stardom – and Alisha Glass stands out even among the greats,” MHSAA Executive Director Mark Uyl said. “Taking into account everything she accomplished individually and with her teams, and not just in volleyball but basketball as well, it’s a strong argument that Alisha Glass continues to set the bar as not only our state’s best female athlete all-time, but arguably the most accomplished volleyball player in national high school history. We are thrilled that she will be inducted into the National High School Hall of Fame.”

Glass celebrates with her teammates during a match.Also during high school, Childress played on the 2004 and 2005 USA youth national volleyball teams and helped the 2004 team to the North, Central America and Caribbean Volleyball Confederation (NORECA) championship, and was named Best Server at that event. After high school, she started all four seasons at national power Penn State and set the Nittany Lions to three straight NCAA championships, being named to the American Volleyball Coaches Association (AVCA) All-America first team twice and second team once.

Childress continued her career professionally and internationally, playing professionally in the United States and Puerto Rico, Italy, Turkey, Poland and Brazil and being named USA Volleyball Indoor Female Athlete of the Year for both 2013 and 2014. She led the U.S. national team to bronze at 2016 Olympics and was named Best Setter of the tournament, after being selected as an alternate for the 2012 Olympic team.

Most recently, Childress played for the Pro Volleyball Federation's Vegas Thrill in 2024 and 2025 and played in the league's first All-Star Match last season. She’s currently the head coach of the San Diego Mojo of Major League Volleyball and last summer also completed her first season as a coach with Athletes Unlimited. She previously served as an assistant coach with the Stanford University women’s volleyball program from 2019-21 – including during the team’s run to the Division I national title in 2019 – and also served as an assistant for the gold medal-winning U.S. national team during the 2018 Pan American Cup.

Childress is the daughter of Laurie Glass, who retired from coaching Leland after the 2023 season and ranks seventh in MHSAA girls volleyball coaching history for victories with a career record of 1,259-410-124. Glass led Leland to three Class D championships and five runner-up finishes. Childress’ grandfather Larry Glass ranks on the MHSAA girls basketball coaching victory list with a 388-110 record and led Leland to three straight Class D titles from 1980-82. He also coached the Northwestern University men’s basketball team for six seasons.

Additionally, Childress is married to past Stanford basketball star Josh Childress, who went on to play eight seasons in the NBA and several more overseas. They have three daughters, Maya, Mina and Amara.  

The National High School Hall of Fame was started in 1982 by the NFHS. The 12 individuals were chosen after a two-level selection process involving a screening committee composed of active high school state association administrators, coaches and officials, and a final selection committee composed of coaches, former athletes, state association officials, media representatives and educational leaders. Nominations were made through NFHS member associations. Also chosen for this class were athletes Joe Carter (Oklahoma), Jordan Larson (Nebraska), Krissy Wendell-Pohl (Minnesota) and Patrick Willis (Tennessee); sport coaches Jan Barker (Texas), David Gentry (North Carolina) and Flo Valdez (New Mexico); game officials Burney Jenkins (Kentucky) and Mary Lou Thimas (Massachusetts), former state association administrator Steve Savarese (Alabama) and former fine arts educator Craig Ihnen (Iowa).
