Can anyone knows how much allowance rate should a certified programmer in SCJP 1.5 receive? or is there a site available where I can view the standard salary rate or allowance rate of an SCJP 1.5 certified programmer?
I don't think it is possible to say what the standard salary rate is for an SCJP certified programmer. It depends on in which country you live, maybe even in which part of which country you live, and different companies may have very different rates.
There are a few sites that do list what SCJP programmers make on average. But like Jesper said it is really dependent on where you live. A SCJP programmer in the Philippines might make 6-7,000 per year where as s a similarly skilled person in Silicon Valley might make 100,000. Just depends on the region.
Though this may not be what you are asking, I think that the SCJP is important but that in and of itself is probably not going to be the major factor in getting hired someplace.
