You should include a little more information about yourself. It's a little short.Dear Sir or Madam,
I am applying for the Postgraduate Diploma of Information Technology Management, as (remove 'this is') my first step in pursuing the Master of Management in Information Technology.
With over 10 years of experience dealing with technical aspect of IT, and now as a Technical Manager, I do feel a need to see the context from other side. Having two certifications, PMP and CSM ( Certified Scrum Master ), indeed helps (removed 'me in that purpose'). I believe that this is still not enough. Having an MMIT will definitely improve my abilities to think "out of box", as well as (remove 'to') bolster my career progression.
There are many specific reasons why I want to pursue the MMIT at [xyz]. I've compared the MMIT subjects from various university. To name the few, the academic reputation, the availability of an extensive range of courses, and the online courses, perfectly suit my interests.(I think you should not name any colleges, but just say that your course structure and curriculum and subjects match my goals)
I am confident that I am qualified and will give my 100% in this programme. I would be grateful if my application for this programme is considered and accepted.
