USDT/FAA-H-8083-3 Airplane Flying handbook
page 1-1:
"Some flight schools are referred to as 'FAA approved schools.' An FAA-approved schols is certificated by the FAA and is required to meet certain stantdards regarding airplanes, personnnel, and curriculam. Another advantage of an approved school is that it may offer some courses of training with fewer flight hours"

So again, my question is, is above talking about 141 school as "FAA approved school"? or can all(61 and 141) school can and can not be "FAA Approved"?

thanks
