You can check the status of your entry by logging in to the
FRC at Home Portal and taking a look at the
status information for each competition you are participating in.
Please note: There is a delay between actions taken in the Entry Submission System and the status reflecting here in the Portal.
Information is synchronized a couple of times per day. This delay generally only affects data coming from the Entry Submission
System, not the other direction.
You can also check the status inside the Entry Submission System. Look for the Status column on the landing page upon successful login (marked below in red).

If the Status says "Submitted and Locked" then the entry is completed and valid, even if it is not yet reflected in the Portal here on frc.events.
If the Status says "Pending Submission" then it must be submitted by the team prior to the deadline in order to be scored or judged.
