GLSS provides the training. Certification is awarded by an independent body, with its own exam, that you choose. No certification exam is included in our courses: it is a separate step, on top of training, depending on the certification body you select. This applies in Greece, Cyprus and Europe.
Training and certification are different things. Keeping them separate protects the value of your certificate.
Live training by GLSS, with tools, exercises and real examples. It prepares you to apply the methods and to sit the exam.
Run by the certification body under its own rules: online or at a test centre, usually in English, with its own fee.
Awarded by the body when you meet its requirements. The body also decides whether and when renewal is needed.
Live training, course materials, exercises and guidance from the trainer during the course.
The exam and certification by an external body. Their fees and terms are set by the body you choose.
We explain the options, help you choose a body and guide you through exam registration.
Each body has its own rules for the exam, language, projects and renewal. We confirm them with you before you enrol, because they change over time.
