I was required to attend Lead Firearms Recertification at Glynco every 3 years. Never turn down an opportunity for a FLETC course and have fun however comma. As far as Agency training it was so so And as RT3 mentioned some instructors are better than others and a lot of SOP stuff that we should already know. In my view it also was more saftey observer institutional inbreeding type stuff..
Now some advanced training was better. But again that can depend on instructor and other students as some don't want to be there (much like qualifications)
As Wayne Dobbs stated folks like Paul Howe and the like would probably be 3 levels above.And they follow experience over an agency "script I recently attended Handgun Combatives course on my own dime and it was excellent.
So my advice do all the FLETC stuff is able but seek out some vetted instructors in the private sector as well.
