Need help abbreviating my credentials

[chuckzoo]

I am writing a formal letter and need to add my credentials. It has been such a long time since I have needed to do this I have forgotten the abbreviations!

How do I abbreviate the following; Diploma - Public Relations, Diploma - Human resource management, BSc, MSc?

Are the diploma's certifications or AAs or something else?? Generally, you would just put the degrees for the abbreviations (AA/AS, BSc, MSc), but not certifications unless they are agency-given (such as a REA for Registered Environmental Manager)

The diplomas were earned through a Management School. The courses each took two years to complete.

Ok...I did some pokin' around online

DHRM for Diploma in Human Resources Management

I couldn't find one for public relations, but there must be one
