Does the current Structured Self Development course system efficiently promote Professional development?

However, I think that if a Soldier does not show the initiative or desire to do what is required of them to advance, well then maybe a bar to reenlistment should be placed on them for failure to advance, keep pace with peers, show leadership potential, etc.   

The SSD DL is not that difficult and should not be that big of deal.  You can even google all of the answers I am told.

Oh look, the army says I am required to do something if I want to stay in, advance, or attend NCOES, let me go ahead and do that so I am not viewed as a malingerer or someone who is just doing the minimums. 

The mediocre thought process is what they are trying to weed out of the military these days.  I want Soldiers who take initiative and go above and beyond in my formation.

Now the other side of me says: don't force them to do it, don't pressure them.  Let the one's who do want to excel and be a part of the Army team advance over them.  Let the one's who do not want to complete an Army requirement do their time and just get out.  So I am torn between let it be and force them to do it.  Either way, those without the initiative will be weeded out.  Definitely should be no form of punitive action against them for not doing it at any rate.
