Training Course [2]
A short period of study, typically from an hour up to several weeks or months (especially if attended, for example, on one-day or part-of a day or evening per week).
The course might therefore focus on either a specific skill or knowledge requirement to a general introduction and overview of a subject area, essentially acting as a catalyst for further study.
Training courses might consist of one or many lessons and be aimed at individuals wanting to gain new skills or knowledge, especially so they can carry out a specific job task, or for preparing them for job roles, or other individuals wishing to have a refresher course on previously gained skills and knowledge.
