Differences in SOP between NSF GRFP and school applications

[tlevine]

I recently submitted the NSF GRFP application, and now I'm finishing my school applications. I'm wondering whether I can leverage my understanding of the NSF GRFP application for writing the school application statements of purpose. I'll phrase my wonder as a couple of questions

1. How do NSF GRFP personal statements (or equivalent statements on other fellowship applications) and graduate school statements of purpose?
   
2. The NSF GRFP application explicitly lists review criteria, but the school applications are less explicit about review criteria. Do school applications have some equivalent to the review criteria?
   

I'm wondering about applications to ergonomics programs in schools of engineering and schools of public health, but I suspect that answers for other fields will help. And here are directions for the statement the NSF GRFP and for the schools to which I'm applying.

I'm also curious about this.
