What should employees keep after an AI training program?
Attendance at a session gives an employee little to bring to a development conversation. A short portfolio of permitted examples does more: the task, their contribution, what they checked and the feedback they got.
The culture discussion linked learning with opportunity. When people build the portfolio, have them strip out confidential material and follow your organization's rules for retaining or sharing work.
Add a difficult case and what the employee learned from it. Competence includes recognizing a limit and correcting a mistake, and it includes knowing when to bring in another person.
Make the next development goal specific. Someone might need more practice with source checking. For someone else it's explaining a result or handling exceptions. A single score would hide that.
Use the record in a conversation about actual responsibilities and opportunities. A portfolio doesn't guarantee promotion or redeployment, so don't promise that. What it can do is give the employee a clearer way to explain what they can do and what support would help with the next task.
