Student Athletic Trainer Try-Out Information

Spring Football Starts April 28, So packets must be turned and meet the requirements by listed date on the try-out packet to be eligible to try-out. 

Athletic Training Room Rules

1.  ALL students in athletics MUST have the appropriate UIL physical forms on file in the athletic training room before they are cleared to participate in their sport and or recieve treatment. This includes any practice, before, during or after school, both in-season and out-of-season. The paperwork MUST be turned into the Athletic Trainers for review before being cleared.
2.  Morning treatments are for In-Season sports injuries only unless otherwise directed by the athletic trainers.  Off-Season sports injuries are done during the sports athletic period or afterschool if no coverage is needed.
3.  Report all injuries to the athletic trainers and/or coaches. Injuries should be reported as soon as possible. If you miss morning treatment time during in-season sports, you will not be allowed to miss class unless there is an emergency.

4. We DO NOT accept notes from parents excusing you from participation if you are sick or injured.  It MUST be a physician’s prescribed plan for treatment! Please report for treatment at scheduled times!
5.  Please notify the athletic trainers if you plan to see a doctor for your injury. Athletes MUST submit a doctor’s note immediately upon return to school. We must follow doctor’s orders, including return-to-play guidelines. If you are seen by a doctor you can only be cleared to play by a doctor unless otherwise indicated.

6.  If you are injured outside of school sponsored activities please DO NOT come to the athletic training room for an evaluation.  All club sponsored activities DO NOT fall under school sponsored activities. You must visit your own physician and request an evaluation.  Rehabilitation for such injuries will be at the discretion of the Athletic Trainer.
7.  Report to your coach at the start of the period before coming for treatment. Immediately after treatments are over you will report back to your coach.  Athletes will continue treatments until CLEARED by the athletic trainer or doctor.
8.  Morning treatments are from 7:30-8:40 am every school day unless school activities are directed.  

9.  Dress appropriately for the athletic training room. NO sports bras, skirts, etc. Also, we do not allow shoes to be worn in the athletic training room for sanitary reasons.  

10.  The athletic training room is not a place to "HANG-OUT" or "LOUNGE". It is a medical environment and should be treated as so.

Being in the Athletic Training Room is not an excuse for being late to practice!!!
