CF Centers are ranked by the CFF. Some centers will share that info with you.
The CFF, however, won't share that info because they feel it would hurt some CF centers. Duh! I wouldn't want to go to a low-ranking CF center.
Some items, to the fair, in the rankings are really indicative of a "good" CF Center. Items such as body mass index are included and for me at least, I don't think that is indicative of how good a center is.
But other items like frequency of PFT's, diabetes testing, bone density scan, etc are good indicators. Survival age is good as well. Some people argue this is highly correlated to socio-economic status, which COULD be true. But I know places like Minnesota, where they've had access to the Vest and excellent docs for years, have high life expectancy cuz it's a great center. Period.
So that's the scoop. Hopefully your center will be open with you and let you know their rank.
