They have the necessary *training*, Albert.

I don't need *training* because I have a degree in electronics,
it would be more usual for me to provide training to people
with less capabilities.

You clearly don't understand the great difference between 'education'
and relevant/specific 'training', for which trainees' prior capability
is often irrelevant.

'A degree in electronics' could give you claim only to 'some education',
but you're labelling yourself as, in a broader sense, 'woefully
ill-educated' to to the point that one wonders at your employability as
a provider of training ...
