In my point of view ABET /PE/FE not important , i will speak about my experience , u will see in market much engineer from qualified university but when you invite these people to vacancy interview u will feel that people in the engineering theory information are weak comparing to other people was diploma engineering and after some times they get bachelor degree by distance learning university and meanwhile all of the on line university not accredited ,but these people u feel they are experienced in design and technical work ,and in his time and in the presence of internet and you tube self learning became more practical what u need you will find any information so it is not a judgment that if person university not accredited or holding ABET he is not engineer also learning from life experience during work are big university ,experience and the information and the practical work certifies engineer .
