I did. I had a business-related Bachelor's degree and was working in Human Resources. While I liked my job okay, I never felt passionate about it and couldn't see doing it as a career for the rest of my life. So, I listened to my gut and went back to school to teach.
My program was a Master's program designed for people who are working full time. Classes were on weekends and evenings. They have elementary, middle, and high school certifications. All told, it was five semesters of very intensive work. That inclues your student teaching semester.
As for working full-time...many people in my program did it, some with kids. Myself, I worked full-time for 3 of the 5 semesters and eventually got so frazzled and tired that I quit my full-time job and started working part time as a nanny. My program was feasible for those working full time, if your job was flexible. For instance, we had to do a certain number of observation hours in local schools per semester. Most people just took time off from work to do that, but if you didn't have the vacation time and/or flexible boss, that could have been an issue.
Then, of course, comes the issue of the student teaching semester. I would have had to quit my job anyway to do this, with no guarantee of a job afterwards. Some lucky few could take an unpaid leave from work, most had to quit. You also have to deal with making no money for several months because it's so much work, you can't get a night job. But, everyone found a way to work it out.
I know job prospects vary from state to state, but I had no problem finding a job after I graduated. I graduated in December and started teaching at a wonderful school in January. Most of the people in my program also found jobs right away.
It was a challenge, and scary at times, but it was a wonderful decision for me. The hugs from the kids, the smiles, the "breakthroughs" with difficult children - it makes my day every day. There have been many times I cried out of pure frustration or sadness, there have been times I doubted if I would be a good teacher or not...but through it all is a feeling that I'm finally doing the "right" thing. This first semester of teaching has been very, very emotionally difficult and very rewarding too. Do not ever go into teaching if you want a job you can forget about at night. You can't - I think about my job all of the time. Sometimes that gets on my nerves, but I know it's worth it.
I hope I've given you some information you can use. Please, please feel free to PM me with questions. I would have loved someone to bounce ideas off of when I was just beginning this process. Good luck with your decision!!
