First of all, I believe in living from your inside out, basically making the best out of your situation. A lot of people blame circumstances for their position in career and life, I believe that I am in control of effecting my circumstances based on how I respond. That being said, take into consideration that MNPS is an inner city school district. You will face the challenges of povery mindset and poverty thinking in your classrooms. I choose to look at this as an opportunity, rather than a hinderance. I believe that the leadership of the organization as a whole has great intentions for the school district, but they need buy-in from the teachers and other stakeholders to make their vision succeed.
As far as teacher pay is concerned, teachers obviously don't make a lot of money. If you go the administration route, you could potentially earn 100k+, but other than that, there is not a lot of room for advancement. You just have to ask yourself if the higher degrees and debt accumulated in achieving those are worth the financial payoff.
The benefits are great, and in my experience, I have had a good relationships with my principals and other leadership. I do believe they have the best interest for the students and teachers in mind.
The size of your success, however, is determined by the size of your thinking. If you have small thinking, you won't thrive here. However, if you believe every child has greatness inside of them, you will do well. It's all up to you.
