I'm going to ask Ms. Crescenzi to tell you more about the training inspectors receive. You raise a very important point.
Keep in mind that, when we hire inspectors, we train them internally. During the pandemic, on one hand, we doubled the number of inspectors, but on the other, we were losing 30% of our inspectors and employees annually. That was our attrition rate. That is why I said we were building and flying the plane at the same time. Much of the training is delivered in house.
Mary, do you want to maybe be more specific on the training?
