In working as chemist for the past 20 years, I have been both the trainer and the trainee. These experiences range across various laboratory settings, from three laboratory employees to hundreds. Each laboratory defines training differently; a well-established process by which someone is taught the skills that are necessary for a profession or a job. It also has well-defined learning objectives and formality.
In modern day training, there is a strong focus on the trainer being a subject matter expert. The trainer has extensive experience or knowledge in the subject that is being delivered. It is expected that the participants in the training learn from the trainer. It is a formal process in which guidelines must be followed objectives accomplished, and skills verified.
