Start by translating the vacancy into evidence categories. Internal roles often come with a job description, grade framework, competency list, success profile, leadership behaviours, or informal expectations from the hiring manager. Do not treat those documents as admin. They are the scoring guide.
Read the advert and highlight the words that signal a step up. These are often phrases such as “own”, “lead”, “manage”, “influence”, “strategic”, “continuous improvement”, “stakeholder”, “budget”, “risk”, “quality”, “coaching”, “commercial”, or “service delivery”. Then match each phrase to proof from your current job.
For example, if the promotion requires team leadership, do not only say you are helpful. Show where you trained a new starter, coordinated cover, supported underperforming colleagues, ran a handover, or led a piece of work while your manager was absent.
If the promotion requires commercial judgement, show where you improved a process, reduced wastage, protected margin, improved forecasting, retained a client, or spotted a risk before it became expensive.
If the promotion requires stakeholder management, name the types of people you worked with rather than listing every colleague. You might mention senior managers, operations teams, finance, HR, suppliers, clients, regulators, students, patients, or service users, depending on your sector.
This planning step stops your Internal Promotion CV becoming a career diary. It also protects you from a common internal-candidate mistake: writing for people who like you rather than writing against the role criteria.
