Currently, US Soccer makes web-based concussion education information available, including a video about concussion reporting called "Recognize to Recover."

Before every regular season game, participating teams in league randomized to the Pre-Game Safety Huddle condition will hold brief Pre-Game Safety Huddles. Pre-Game Safety Huddles have three core components: (1) Gather (Athletes, coaches, officials, and other stakeholders come together before the start of the game); (2) Share (Opinion leaders (coaches, referees) affirm the importance of seeking care for suspected concussion, and (3) Repeat (Process is repeated before every game)

Concussion Reporting- Expectations (CR-E), a 4-item scale that assesses athlete's expectations that they would tell a coach or other trusted adult about post-impact concussive symptoms in naturalistic scenarios. Responses are measured on a 4-point Likert scale, with higher sores indicating a stronger expectation that they would report future post-impact concussive symptoms.

Identification of suspected concussions will be measured via coach report as the number of times per season an athlete was identified as having a possible concussion (from 1- athlete-report to a coach, medical personnel or parent report to a coach, or 2- athlete removal from play for suspected concussive symptoms without report, for example due to loss of consciousness). This will be expressed as a team-level rate (number of instances/number of athletes per team).

CR-N is a 4-item scale that assesses the coach's perception that coaches in their organization would want athletes to report suspected concussive symptoms. Responses to four scenarios are measured on a 4-point Likert scale, with higher sores indicating a stronger perceived norms in support of reporting future post-impact concussive symptoms.
