Here in Syracuse, NY you must prove 10 years in the trade, 5 years commercial , of which 3 years must be new construction, ground up not remodel. This qualifies you for the masters test. The test is given 2 times a year and usually a very low number pass the test, I was the only one of 15 to pass when I took the exam. Syracuse no longer has recipricals with any other jurisdictions in this area.
