USL Certification Information

This page details the steps every official must take in order to complete your US Lacrosse certification. Officials who are between 14 and 18 years old and still in high school MUST complete USL certification in order to work.  Adults (over 18 and high school graduates) are encouraged to complete their USA Lacrosse certification as that will be the only insurance other than their personal insurance when they work non-GHSA games. In addition, many summer and fall tournaments now require officials have USA Lacrosse certification.

Classes for youth officials are ONLY held in the Fall around the Labor Day weekend. 

Adults are trained in the Fall and in January prior to the Spring high school season

It is VERY IMPORTANT that you read ALL of this information carefully. 

USA Lacrosse Membership

All youth officials (18 and under and not graduated from high school MUST be USA Lacrosse members.

Adults who plan to do GHSA games who are not USAL members are encouraged, but not required to join.  Adults who only want to work youth games MUST be USAL members. 

Non-USA Lacrosse Adult Members

Adult officials (18+ and graduated from high school) who are not USAL members must take the Fall GLOA Rules Exam and pass with an 85 or higher. All Adult officials who work GHSA games are required to take the GHSA clinic and test in January prior to the Spring season.

Six Steps to Completing Certification

To become a certified USA lacrosse Official you must complete ALL five (5) of these requirements.

Please click the links to learn more about each step.

  1. Register with USA Lacrosse. Many of the problems that arise are a result of expired or linked memberships. If there is a problem you will need to call the US Lacrosse members services at (410) 235-6882, ext. #102 or email

    Do not use your parent’s email address!  

  2. Complete the “Boys’ Lacrosse Rules Online Course” via the US Lacrosse Learning Platform on the USAL website before the class. This course is a brief introduction to the rules and officiating. THIS IS NOT THE RULES TEST.  You only need to take this online course once.

  4. Pass BOTH the NFHS and Youth Tests (85% or higher) BEFORE Field Training. These must be taken online! Please wait to take these AFTER you have your rule book and have taken the class.

  6. Complete Field Training. Slots for field training games will be sent out via SignupGenius and open to these who complete all requirements on a first come, first served basis. You MUST be in full uniform for these filed training games.

    More information will be sent out once you have registered.  If you are unable to do so or have a conflict we will work with you to schedule a game on another date. However, If you can’t complete this field training this fall you start the process over.

This is the place where you can access the “Boys Lacrosse Rules Online Course” as well as both tests. 


You must use the email you have registered with your US Lacrosse account; NOT your parents email. The course MUST be completed under your account, if not you will need to retake it. 

Please complete on a laptop or desktop computer. You may experience technical issues on tablet or mobile browsers.

This course is FREE for all current USAL members. If you are being asked to pay, check with member services regarding your account (see above).



Please note that payment is required, preferably via PayPal, prior to attending class. If you are having difficulty, please contact Greg Hite at

Communication Policy 

Becoming an official is a serious undertaking.  Your child will be responsible for maintaining a safe, fair and fun contest ever time they officiate. They are in charge, not the coaches or the parents.  When they join a league or association, they will be responsible for regularly communicating with assignors, league and team administrators, and fellow officials.

Officials must have their own email address. Parents can not share an email adddress with their child. 

If you have a question, YOUR CHILD should be the one to contact me. 


It is essential that you begin to put your uniform together immediately. You will be officiating your field training game, so you need to be in full uniform. Most of the stuff we use, we buy online.  Be aware that you need to allow for delivery time, so plan ahead.  It is important to look professional, but you do not need to spend a lot of money to do so.  Target, TJ Maxx, and Amazon are great places to get deals on shorts, socks, and shoes for officiating. When in doubt go all black!
If you are a new official, focus on the key pieces:
  • Good hat (black with white pipe for Spring, all white for summer and fall)
  • Correct short-sleeve shirt (2″ for GHSA games (adults only), 1″ for youth games and/or green shirt for fall and summer games)
  • Black shorts
  • Black shoes
  • Black ankle socks.
You can always add to your collection (long sleeve shirt, jacket etc).
You can check out more info on uniforms and equipment including where to buy online and in Atlanta on our Uniform and Equipment page. 
There are differences between youth and adult uniforms as well as spring and off season uniforms, so please read carefully.
slider2summer1Fall leagues are a little less formal. Most GLOA adults officials wear white hats (you can use any white hat or purchase a GLOA logo hat) and green summer/fall shirts.  These can be purchased on our GLOA Gear Store.  Adult officials who work games this fall will be reimbursed for their shirt.  Please SAVE YOUR RECEIPT. 
The biggest piece of equipment adult officials need to purchase is a 20-second timer.  
Youth officials should purchase a 1-inch shirt sleeved vertical black/white stripes with black collar and black cuffs and a pocket on the left breast. Youth and USAL adult members will receive a US Lacrosse Patch at your field training.  Youth officials who wish to purchase a green GLOA summer shirt are more than welcome to do so, but will not be reimbursed.  
20-Second Timer
20-second Timer (ADULTS ONLY) There are 2 types: the 20 second timers and the 1:40/20 second timers, the later is great for managing time outs and time between periods. This is the most expensive piece of equipment you will purchase.  You CANNOT work High School games without one. 
Youth refs do NOT need to purchase a 20-second timer as the games they work do not have a 20-count.
Make sure you have your USAL patch sewn professionally on your shirt 3″ below the top seam on your left shoulder.  Do not iron it on.  
If you did not receive a patch, please let me know and I will mail one out to you. 

Getting Games

 As we stated in class USA Lacrosse DOES NOT assign games.
In order to get games, you need to join a league or association. 
registerThe largest association is the Georgia Lacrosse Officials Association (GLOA), that is the group that all GHSA officials are members of.  The group that ran your training was the GLOA. You can visit our website at You will also find regular updates on rules and mechanics on the main page.
If you can’t drive, may also contact your local youth team or your high school coach to see how they assign officials; it may ve through GLOA or they may assign officials themselves. 
Most leagues (but not all) use an online assigning system called arbitersports (think of it as signupgenius on steroids).
Once your application has been approved by your league or association, they will send you an email inviting you to their arbiter account.  Be sure to be on the lookout for that email as it might go to your spam folder.  
Here is an article on how to use Arbiter.
Remember: You must check your email DAILY.  
If you do not accept a game, you will be removed after a few days and assignors will be unlikely to assign you again.  If you accept a game, you MUST show up for the game.  If you do not block a date, you are telling the assignor you are available, so be sure to update and manage your calendar REGULARLY.


You are certified through January. 
You should automatically receive a copy of the NFHS rule book from USA Lacrosse each year.  
Each spring you will need to recertify by:

    • renewing your USAL membership.
    • take the latest NFHS and Youth tests.
    • watching the latest rules videos.
    • attending the free GLOA ONLINE recertification clinic.

Adult officials must also attend training sessions in January. 

Be sure to check regularly for updates.  

You must continue to put work into being a referee by staying in the rule book and the mechanics manual, working games and asking questions.  Remember, this is the beginning of your training not the end of it!  If you have any questions please let us know!
As always if you have questions, please reach out to me.
