In my environment Botswana , Southern Africa its is :
1) Relevant Academic Qualification :Certificate ,Diploma Bachelor of Science , Bachelor oF Enginering , Msc , etc in a related field.
2) Complemented by Industry Certs. e.g CCNA, CCDA, MCP, MCSE , Comptia tech Certs A+, Network+ , etc ,
For supervisory and Managerial Jobs : ITIL , IT Project+ , Strategic Management (Generic or IT Strategic Management).
Experience however at employers discretion can be considered in lieu of the above , with the possibility of a hands on screening exam .
My current position (ICT Network Manager) required :
i) Degree in Computer Science/Engineering or Electronic Engineering , the latter being what i graduated in .
ii) Professional / Career Cetrt e.g. CCNA
At he time of applying I held a valid CCDA.
iii) IT Management Qualification : e.g. ITIL

I reckon you need all of the above , education , certs (tech and IT Managemnt) and relevant expreience.
Else prepare a comptency based resume based on :
Tech Skills , Management Skills, Best Practice Competencies (ITIL, COBIT,ISO17799 etc) etc
