When you or your supervisor are planning attendance at a training course there is an important consideration to keep in mind. Have you met the prerequisites for the course you have selected? These prerequisites are dictated by the company presenting the course and take into account basic knowledge about the subject as well as exposure to the subject. If you do not have the prerequisites this can make the learning objective difficult at best. Across most industries,  timelines for taking most courses are determined by how attendees do based on their knowledge level.

In the vibration world, it helps if the student understands the terms of the subject and has had at least some exposure to the subject. When attending a vibration hardware course it is good to have had some hands-on experience, as those students tend to ask more questions and therefore get more out of the class.
If attending a software course, having at least basic computer skills is helpful. Remember, if you’re a novice there may be attendees far more advanced than yourself in the class, but if you’re more of an advanced user you may have attendees with far less experience than yourself.  Courses are seldom taught for either the novice or advanced user. The material presented is in the middle of the class average. That does not mean that you should not attend the training class. Only that you make sure the course instructor knows your experience level. A good instructor should at the start of the course have an introductory period where you’re allowed to introduce yourself and convey your experience level.

Remember that everyone in a class started at some point with no experience or knowledge.
