Work Experience as of Application or Start Date

Quick question for all of you GMAT experts, when you see on the site that a school has an average work experience of 60 weeks for example, does that mean that the average person has 60 weeks experience at the date of application or will have that experience at the date they start their classes. Obviously, those dates can be up to 12 months apart so it's important to know which is meant.

Thanks for all of your help
