Why We turned to Big Data
![Page 4: Analyzing Big Data: The RI Referee Ranking System](https://reader036.fdocuments.net/reader036/viewer/2022062418/55634dfbd8b42a90698b5321/html5/thumbnails/4.jpg)

Opportunities to Educate Referees
“Brian, ###### is so upset. How is this ranking done? What are the qualifications? He is trying like crazy to be a great ref, but it seems he almost never gets ref assignments, simply ARs. He will be taking the fitness test and the ODP ref class. I understand there is a RI Ref Academy; could you tell us about it?”

Opportunities to Educate Assignors
“Could you please give me some info on how the referee raking is compiled? I have some referees that I feel should be able to make the list.
I was looking at the link you sent out to the refs of the top 100 under 25 years old and I see that ranked 47th you have ###### from Pawtucket and I am wondering how he made the ranking seeing how he just got certified for the first time this year and he has never refereed a game until this weekend.”
