Use the Position Description as the preparation map
Mark duties, capability words, classification-level signals and repeated themes. These are the areas your examples need to prove.
Show your level of ownership
Panels need to understand the judgement you used, the trade-offs you considered and the result you influenced.
Keep STAR evidence clear
Spend less time on background and more time on your action, decision, stakeholder work and result.
Use credible public guidance
Public guidance such as APSC Cracking the Code can help candidates understand merit-based recruitment. ACT adds a role-specific practice and feedback workflow.
