Scoring a loan application against past repayment outcomes
Fits a model to the outcomes of past advances — repaid, rolled, written off — and returns for a new applicant a probability of default together with the features that moved it, which a credit officer applies inside a written policy that still owns the cut-offs, the overrides and the list of who may exercise them.

What to check before you ship it in India
- The score drives a decision about an identified person, which engages section 8(3): the Data Fiduciary must ensure the personal data is complete, accurate and consistent where it is likely to be used to make a decision affecting the Data Principal. A stale bureau record or a mis-keyed income is therefore the lender's problem, not the model's.
- Where the lending is digital, the Reserve Bank of India (Digital Lending) Directions, 2025 require the Regulated Entity to obtain the borrower's economic profile — age, occupation, income — before extending the loan, so that creditworthiness is assessed in an auditable way. A score whose inputs cannot be reconstructed as they stood on the decision date is not auditable however well it discriminates. A lender outside the Regulated Entity perimeter is not reached by this.
