Erik:

I've written numerous grants and none are exactly the same.  The main thing you have to do is read and follow instructions.  Stay withing defined limits - page length, margins, characters, etc.  Most will want to know about you, why you deserve the money more than someone else.  You have to sell your need and prove that you're capable of doing what you say you'll be doing.  Goals should be realistic.  If I was to sum up a boilerplate grant, however, it would start with an Executive Summary (like a book report of what's to follow).  The Narrative would include 1) need, 2) project design which should include a logic model (do a Google search for Logic Model) -  input, activities, outcomes, goals, and objectives, 3) your capacity to deliver - past experience and achievements, personnel, partners, 4) how you plan to evaluate the effectiveness of your project, and 5)letters of support.  There are lots of resources and training available to teach you about writing grants.  I received my training through the Grantsmanship Center, www.tgci.com.  There are also state agencies, like Maryland Non-profits that provide low cost training. 

I can't emphasize enough, follow the rules like making a cake from a recipe.  Make sure you're answering all of the questions they ask.  Use their language in answering, too.  The grants are sometimes reviewed by people who aren't real familiar with the topic, so explain yourself clearly without using acronyms or language unknown to someone who is not in your profession or community.

Good luck!
