Some workers may be able to walk onto a job and get their hands around it immediately, but for most new employees, training is necessary. That is why trainers are important! It is the trainer’s job to ensure that employees have the knowledge, ability and confidence to tackle their new job.
It is important to realize that any trainer needs two separate sets of skills and knowledge. First, they need to know the topic they are teaching (subject matter expertise). Second, they need to know how to transfer that information to the student (instructional expertise).

Great Training leads to the following positive results:
Employees perform their jobs with more confidence
1- They learn more quickly
2- They work more accurately
3- They get along better with other employees
4- They work better in teams
