Based on your first post, I would consider you ANSI 3.1 qualified and as AG stated possibly considered for a line supervisors position, without any major questions! But, and there is always a but, the individual reviewing and making the determination may not understand Art. 108 quals and thus determine NQ, depends on the individual, plant, utility, site, etc., how they make the determination.
Day 1, probably not! You would still have to qualify to the specific program. Given your background as stated, a piece of cake. Depending on the plant, utility, site it could take a week or two before you are good to go and then a while for everyone to get a warm-fuzzy.
Since I don't know which SY program you're talking about, that's the best I can offer. Feel free to PM me though and I might be able to offer more help.
