Ok, I read this as the EA or FC examination can be done at a called or stated meeting as per Art. 235 and 436 as Bros. Hale and Blake stated. The Masters examination is done in accordanance with Art. 439, Examination in the Master's Degree. This just states that it must be done in an "open" Lodge. That leads me to believe that it, just as the EA and FC, can be done in called or stated.
Personally, I have never seen a lodge perform examinations at a Stated Meeting.
