Pros
TeachNOLA (the New Orleans branch of TNTP) is the best way for people with no prior experience in education to become teachers in New Orleans. New Orleans is a demanding place to teach, but teachNOLA's summer academy is specifically tailored to address conditions specific to the city. The summer academy staff are themselves full-time teachers who back up their instruction with real world experience. The staff are attentive to fellows' needs and have a vested interest in preparing fellows (their future colleagues) as thoroughly as possible for their first year of teaching. During the school year, you will receive feedback on your performance from a coach, who visits several times a month. The feedback I received from my coach drastically improved my performance. All in all, teachNOLA staff are high quality, responsive, and provide support when you need it.
Cons
TeachNOLA requires a massive time commitment, and you will have to adjust your life outside of work accordingly. Summer academy is roughly 12 hours a day, 5 days a week, and you will have to set aside extra time for planning on weekends. There are also mandatory seminars held nights and weekends throughout the year. The time commitment alone is enough to make some people reconsider.
