Question: Are there any world-wide known Music Certification tests that you can take to use in your resume: for example, to demonstrate basic musical abilities?

I used to work in IT, where it is very common for companies like Oracle and Zend to arrange that kind of certification for a programming language or framework.

Answer: 
There are systems of graded examinations in performance for most instruments, and for theory, designed to cover the stages from beginner to pre-college.

Here's a couple of 'classical' ones

and one for 'rock'

Those are UK-based. There are equivalents elsewhere. The next step is a diploma from a music conservatoire.

A few music software companies offer certification in their products. You can become an 'Avid Certified User' in several of their products, including Protools and Sibelius.

Steinberg (Cubase) have 'Certified Training'. I guess you get some sort of certificate after completing a course.

Generally speaking, just about every country will have music exam boards, a lot of them world wide, like ABRSM. Most have been established for many years, and the standard at any particular grade should be just that - standard.

So, on a c.v., stating Grade VI clarinet ABRSM, Trinity, LCM, AMEB etc., should give a good clue to someone reading that c.v., possibly with a little homework.

Worth a look at IMEB - which it seems is the International Music Examination Board, and, as such, would have responsibility to align all boards.
