Structural technology is one that is offered in many flavors....
They do accept independent design experience, too... BTW. It depends on the particular role. Keep in mind that building design experience alot more telling if you can do the job because your very first project you do on your own is going to be more telling then 3 years of hodge podge experience. You can not do an entire project under IDP credit or under any architect prior to licensure On your own. If you do, it is against the law.
If any of you claim such then I can report you to NCARB and your state boards for which you are licensed or NCARB will and you will have your license revoked as well as your IDP credit which may mean you may have to even redo the the ARE. Be careful about such claims because it can come around and haunt you.
There is a few other documents you haven't read which gets into how they may accept other experiences in lieu.
If I took NCBDC cert. Test.... That also would be considered as that alone would demonstrate some working knowledge in all those area noted.
