I like to use pre-test/post-test. It is not the most profound measure of understanding, but it is a measure. More importantly, I have found it to be a key tool in the training. When teaching SPC, for example, I get operators marching in, proclaiming they do not need the training, chock full of attitude. They take the pretest, and they get humbled right off the bat. I tell them that the pretest and post test are the same. It then allows them to focus on the important points of the content. Of course, that means the test has to also contain the important points of the content. So, it ends up being more than just a measurement tool, it is a key facet of the training itself.
I will also note 6.2.2 d): ...ensure that its personnel are aware of the relevance and importance of their activities and how they contribute to the achievement of the quality objectives.
This is actually a very good requirement that has been missed in the past. In automotive, we had people running the machines making product that they thought was "just a screw". Well, it wasn't just a screw, it was a brake part that would kill people if it failed. So, training production operators on the use and importance of the part really is a part of the responsibility of taking an order for that type of product.
Medical and aerospace also typically note that issue. In medical, they showed movies of the device in use. I had to tell them I get it, please turn it off and get me some cold water....
