Which service officers can be appointed as DG?

The appointment of officers to senior administrative roles like Director General (DG) often requires specific qualifications and experience from particular civil service cadres. PAS or PMS officers (Pakistan Administrative Service or Provincial Management Service) are generalist administrative cadres specifically trained and designated for senior management and leadership positions across various government departments and authorities. Their broad administrative experience makes them suitable for such roles. 'Police Service only' and 'Revenue Service only' officers are specialists in their respective fields, not general administration. 'Any civil servant' is too broad, as specific administrative cadres are usually preferred or mandated for high-level executive positions to ensure relevant expertise and consistency in governance.
