Short Answer: Bringing Image Consulting more into the Mainstream
Longer Answer:
Without a standard, it will only slow down the acceptance of soft skills trainers as true professionals.
How so? By having a standard, then the profession can be scrutinized. Your students can be tested independently.
All signs of true professionals.
Really Long Answer:
The motivation behind the provision of the IITTI exam is to bring about
an industry-wide convergence to a single standard for corporate clients, tourists and youths.
A standardized test eliminates conflict of interests,
as the test is conducted by an independent and unbiased body, rather than a test that you set up yourself.
For you, as an image/etiquette trainer, for example,
it allows you to communicate with individual students and corporate clients with more authority and credibility.
Furthermore, a single standard helps you save money by establishing a universal standard for your curriculum.
It also eliminates the need to develop and upkeep your own testing structure -- one less thing to worry about.
It affords you more resources to focus on your training quality and client satisfaction.
