The validate scores button can be found near the bottom of your competition dashboard.
Affiliate Manager who is not competing:
If you the Affiliate Manager but not a registered athlete you can validate scores from the drop down menu under your name at the top right corner of the Games page.
Once you click on the "validate scores" button your competition page you should be taken to the validate scores page. Here you will see any pending scores that have been submitted to your affiliate.
Step 4: Double check the scores before validating.
Make sure the scores submitted are accurate. You should NOT validate any scores that are incorrect. Once scores are validated they may not be able to be adjusted or corrected. If you notice a score was entered incorrectly contact the athlete and see if they can withdraw and re-submit a score before the deadline. If you are validating after the score submission deadline and notice a score is incorrect, contact Games Support immediately for assistance.
