"Formal Credit Training"

What is recognize as formal Credit Training because at my bank I've have being pretty much training in most aspect of credit in an informal way. I pretty much already know how to write credit analysis memoradums, Credit Approval Summaries, underwriting of, Line of Credits, Term loans, stand by letters of credit, Letters of credit. I know how to calculate Credit risk ratios, Debt service calculations, Commercial Real Estate Loans, trouble debt restructuring, borrowing base analysis am I missing something. I'm just saying because an IBD position I'm applying for it says that having a credit training is a plus how would I list that on my resume just put in other information: received hands on credit training? Thanks in advance!!.
