Clearance to Participate in Sports    

Prior to participating in sports, including practices and tryouts all student-athletes must:

  • Register for the sport (click on LION head logo below for Athletic Registration)   AND

Use the same account that was created for past registrations. If you cannot remember the log-in information, please contact the Athletic Dept.

  • Register on Big Teams/PlanetHS (formerly ArbiterAthlete) - Players only (see below for instructions)   AND
  • Have a current physical examination on file in the Athletic Department. Physicals are valid for one year (365 days)  from the date of the last exam.   AND
  • Receive a Clearance Card - Clearance Cards are EMAILED to the parents of the student-athlete once he/she is cleared to participate (ie. all steps have been completed). A copy of the email can be printed out for the coach or the parent can forward the email to the student-athlete so it can be shown on their phone to the coach. Clearance Cards are required for all tryouts and practices. 


Big Teams/PlanetHS (formerly ArbiterAthlete):

CHSAA requires each student-athlete to create an account on PlanetHS (formerly ArbiterAthlete) in order to be eligible to participate in sports. Each student-athlete only needs to do this once (If the student played last year/season they do not need to create another account). This is only for students planning to play a sport. Team Managers do not create this account. 

To create an account on PlanetHS & follow LITTLETON HIGH SCHOOL from your phone, text S40978 to 69274. Text HELP to 69274 for more information. Text STOP to 69274 to opt out. Msg & Data rates may apply. The wireless carriers are not liable for delayed or undelivered messages. Number of messages vary per user.   DO NOT USE THE TEXTING METHOD AT THIS TIME - THEY ARE HAVING PROBLEMS. USE THE METHOD BELOW


This method can be done on the cellphone or on a computer:
