The worst technician I ever hired blacked out my written test...a test 
that some have sat down, looked over, and handed back saying "you don't 
want a technician, you want an engineer."  No, I want a technician who 
knows how to do more than change a board...but that's an epistle.

One of the best technicians had no formal training.

When this problem with technical people showed up, 25 or so years ago, 
we went to a 2 (actually 3) step hiring process.  We have a written test 
we use that they're required to at least take a stab at.  Some people 
clam up in writing, but if they seem to know what they're talking about 
we go to the next step.  That's a workbench with equipment and tools, a 
manual, and a piece of equipment that we've broken for the event.  
They're told to plan on spending a morning or an afternoon.

Back in the old days Tektronix had scope service training at their plant 
in Beaverton, may still do it.  The final "exam" was to troubleshoot a 
scope without taking the covers off and solely from the front panel 
indications.  They would cut transistor leads off, pull them out of the 
circuit, or wrap a wire around them and we had to troubleshoot to the 
base transistor circuit.  I miss those old 453 and 454 scopes.
