Sometimes you may be lucky enough to find a training course which fits perfectly with your requirements, covering all the information you need to know. However this is often quite rare, as open courses where anybody can book onto (subject to any minimum pre-requisites which may apply) need to be quite generic in large parts in order to try and accommodate the needs of everyone in attendance.
As each person will come from a different industry and have varied job roles and responsibilities, it is unlikely that every single part of the course content will be applicable to them. This means that whoever is paying for the course, either themselves of their company, will not be getting a maximum return on investment as some of the time they are spending will be to all intents and purposes, a waste.
The above scenario occurs most frequently on health and safety courses which cover a wide variety of topics and issues. One such example is the NEBOSH General Certificate, the syllabus of which covers so many of the most common hazards and risks which may be present in someone's place of work, as well as policies and risk assessments, means that certain parts will not apply to that individual's workplace role and/or environment.
Rather than putting employees onto open courses which broadly speaking will provide them with the teaching they need, it can often be far more beneficial, cost-effective and more interesting for the attendees themselves if the company arranges a bespoke health and safety session or programme. This will be tailored to the exact job roles and duties of those attending, as well as concentrating specifically on the risks which they may face in their particular place of work. For instance, there is no point in factory workers making stationery products learning anything about nuclear safety or radioactivity hazards, whereas it would be essential for employees at a nuclear power plant. On a generic health and safety course there may be a brief mention of the primary details, but this will actually benefit neither party, as it will be a waste of time for those who do not need to know it, and nowhere near enough detail for those who do.
By cutting out irrelevant information and focusing on exactly what needs to be taught, a bespoke health and safety training course will make far better use of the time available for training, and is more likely to prevent delegates losing interest and finding their attention wandering as they might if they were being taught things they knew did not apply and they would never need. Once their attention goes, there is an increased chance of them missing some information which they do actually require when the topic changes.
