Hi Aijaz, Jessica !!!
I had once posted my thoughts on this here before, but I think I would do it again.
I think that the Certification shouldnt expire.
The reason is very logical. When we graduate and get a degree, its valid for whole of our life.
Its not that we have to again appear for it say after 10 years to keep it update.
When a person graduates as a Doctor he is a Doctor for all of his life. Of course its his responsibility to keep himself upgraded to the latest type of medicines etc. He doesnt need to appear for that exam again.
In the same way, I think, if somebody is a SCJP, he is that way for whole of his life. After that its his responsibility to keep himself upgraded, he should not need to take up the exam again.
Of course this is the way I think.
What do you guys have to say ?
