Six to seven weeks is a workable plan. Loan officers need about 18 hours of learning, two weeks of supervised review on live applications and a final exam and sign-off. Officers who deal with applicants face to face also need practice explaining a decision the agent helped prepare, in words the applicant can understand and the record can support.
What changes for a loan officer
A loan officer sits between the applicant and the credit decision. They gather documents, check the application, assess affordability, explain products, and either decide within their mandate or pass the file to underwriting. An agent can take on much of the gathering and checking: reading payslips and bank statements, flagging missing documents, and drafting an affordability summary.
The officer's job shifts toward two things. First, testing the agent's summary, especially where it rests on what the applicant declared. Second, owning the conversation with the applicant, including when the answer is no. Compliance officers, who set the limits loan officers work within, follow a longer path with more time on the record; compare how long it takes to train compliance officers.
The six to seven weeks, step by step
- Week 1: foundations. About four hours on why agents are governed, depth, the decision chain, and what the lender pays for.
- Weeks 1 to 4: operator learning. About 14 hours, including human review, teaching the agent and when something goes wrong.
- Weeks 4 to 6: supervised review. Real decisions on held applications, checked by a senior lender.
- Week 5: explanation practice. Officers practise giving applicants the reasons for a decline, using the record.
- Week 6 or 7: exam and sign-off.
What the agent prepares and what the officer decides
| The agent may | Stays with the loan officer |
|---|---|
| Read the application, payslips, statements and bureau data (depth 1) | Deciding within the officer's mandate, or referring |
| Flag missing or inconsistent documents (depth 2) | Judging whether an explanation of a gap is credible |
| Draft an affordability summary and product suggestion (depth 2) | Declining an application and giving reasons |
| Send document reminders to applicants (depth 3, where earned) | Any conversation about hardship or vulnerability |
Credit scoring and creditworthiness assessment of natural persons are listed as high-risk under Annex III of the EU AI Act. In the US, ECOA and Regulation B require specific reasons when credit is denied, including when a model is used. Either way, the officer must be able to say why, from the record, without leaning on the agent's phrasing.
The provenance lesson is central. An applicant's stated income is declared. An employer's payslip is signed. The lender's own account data, where the applicant banks with it, is sealed. An affordability summary that rests on declared income for a decisive figure should be held, and the officer should know what to ask for.
An illustrative example
Take a building society's mortgage team of twelve loan officers. Foundations in week one, then Operator learning at around four hours a week. Supervised review starts in week four.
Calibration on the same fifteen applications, using the method in calibration sessions for loan officers, shows that several officers approved affordability summaries for self-employed applicants based on an accountant's emailed letter, which is external, without the filed tax return the agent had marked as missing. The agent had held those files, as it should. The team agrees the evidence standard, practises declines in week five, and sits the exam in week six.
Applicants and brokers sometimes press officers for quick decisions or send documents crafted to steer the agent. That is covered in training loan officers to spot prompt injection and pressure.
What stretches the timeline
- Mixed products. Officers who handle both mortgages and personal loans need cases from both in the supervised period.
- Low volume. Branch officers may see few applications; pool calibration across branches.
- Agent depth. If the agent sends reminders at depth 3, officers should practise reading what it sent, not only what it held.
Procurement officers follow a similar pace with different stakes; see the procurement officer timeline. The full approach is in training teams for AI agents.
Questions people ask
Does the agent change a loan officer's lending mandate?
No. The officer approves what they were already authorised to approve. The agent changes how the file is prepared, not who decides.
Should brokers be told an agent prepared the file?
Be clear with applicants and brokers that AI is used in processing, and that a named person makes the decision. Under the EU AI Act, people must be told when they interact with an AI system.
What if the officer and the agent disagree?
The officer's decision stands, with a written reason in the record. That reason later improves the agent's brief.
