Does anyone have a Fair Lending spreadsheet they would be willing to share for transaction testing?

That is a pretty opened-end question. What type of loans, what are you testing for, etc. There is no one size fits all depending on the risks identified in your fair lending risk assessment and the focal points that you have identified.

A simple one is shown in this document:

The ABA also published a good tool for fair lending testing development:

Just taking some spreadsheet and diving into testing is a very dangerous undertaking. To do fair lending self-testing correctly and have it result in something meaningful takes an awful lot of planning and total buy in by management, the board of director and it never hurts to have legal counsel on board either. Any testing should be conducted under attorney client privilege. While that will not shield the results from your regulator, it will come in handy in case you find something and then any other party brings a civil suit against your bank in the future.

Great resources, thank you very much for sharing.
