Just an FYI as a New York City resident and teacher....there are serious "freezes" in hiring and a lot of speech services are getting cut from the public schools. While the prospect of losing your loans is great, the tough part is getting a job. It took me almost 2 years to find a job in a high needs area.
I just wanted to give you that piece of info!
I think you can never go wrong with a pencil skity and blazer. Anyways, it's better to be a little over dressed than under dressed. Shows you are a professional person, in my opinion.
