We are just beginning to use tri-merge credit reports. When giving the credit score disclosure, must we give all 3 scores, reasons, etc or can we use the "middle" score?

The disclosure provided by our vendor gives all 3 scores.

Under what circumstances would you be required to give all 3 scores or is it just required?

(D) Use of two or more credit scores.

Thank you!
