The "Markom Certificate Examination (Cert.)" course is a typical entry-level course that teaches basic knowledge in the areas of marketing, communication and sales. For this reason, no salary increase is usually paid on completion of the course.
However, it may well be that graduates use the qualification to enter the world of marketing through a new position internally or with a new employer. The Markom exam can be very useful when applying for a position as a marketing assistant or marketing clerk. In this context, moderate salary increases are certainly possible.
The salary or salary development depends on various factors, such as the industry, region, size of the company, professional experience, previous education and age. In terms of salary, another decisive factor is whether the degree leads to a new position and function in the previous company or another company.
