In Luxembourg where I live, the Ministry of Employment encourages further education to improve people's chances of getting a better job through better skills. Among other things, they organise courses in excel, spread over 10 to 12 weekly sessions of three hours each per module, so absolute novices, sometimes learning in what may not be their mother tongue, are eased into the use of whatever skill they are trying to obtain.
The site is in French, but I have copied the links to the detailed descriptions in english of the three modules they offer for excel - which one can join only after one has passed the module on knowing your way around the pc.
This may give an idea of where to pitch for which level of students.
