How difficult is it to get in to NYU Wager and Columbia SIPA?

I am wondering just how difficult it is to get in to NYU Wagner school and Columbia SIPA school. I am currently heading in to my senior year at VCU where I have a cumulative GPA of 3.2 and a 3.7 GPA in my major. I also made the dean's list both fall and spring semester of my junior year. I also attended Universal Technical Institute and Nissan/Infiniti technical training where I graduated with a 3.9 GPA overall. Before getting accepted in to VCU I was employed full time for two years before deciding to go to college. Currently at VCU I am recipient of Academic Achievement Award Grant and Commonwealth Award Grant of Virginia. While at Universal Technical Institute I made dean's list five out of the six times, and was awarded Student of the Course (SOC) once. With my credentials I was wondering if I stand a chance of being accepted in to either of these schools?
