Training Methodology
Pathways Training and consulting adopts the newest techniques of human resources Training and consulting and, with the following:
- Theoretical lectures are delivered via PowerPoint and visual displays (videos and short films)
- Making scientific evaluation to the trainee (before and after)
- Brainstorming and role-playing
- Using case studies related to the scientific material being delivered and the trainees` work.
- The participants get the scientific and practical material printed and on CDs and Flash memories.
- Preparing records and reports of the participants` attendance and results, with a general evaluation of the training program.
- A group of the best trainers and experts in all fields and specialties professionally prepares the scientific material.
- After finishing the course, the participants get certificates of attendance signed, certified, and issued by pathways Training and consulting.
- Our training programs start at 9:00 o`clock in the morning and end at 2:00 in the afternoon, with snack buffet during the lectures.
