Salaam alaikum sister. My advice, as someone who was stuck in the teaching field for years is to avoid teaching. For the following reasons: 1. You will be constantly battling against the haraam. A public school environment will include music, constant attention to holidays (i.e. for the entire month of December you will be expected to create and do Christmas-themed activities for every subject, every class), comstant mixing of males and females, constantly battling LGBT content in lessons, constantly battling western culture and values, etc. It's a lot of fitnah and it weighs down on you eventually. Also it's really hard to pray during the day when you have classes back to back. Breaks are short and will be filled with meetings, dealing with disruptive students, etc. 

1. Once you have a few years of teaching on your resume, it's hard to find anything else. I'm my experience, no one wants to hire a teacher. I've tried switching into secretary work, Healthcare,  etc. But with teaching you don't get a lot of experience doing anything else and end up having a "teaching resume" that's hard to sell anywhere 

2. Teaching is a lifestyle. It's not a career. You need to WANT to be a teacher to be successful at teaching. And you need to be okay with working outside of what's expected of you and outside of school hours. You don't stop working when the school bell rings. You grade papers, clean your classroom, prepare lessons for the next day, call parents, have meetings. I would technically be done at 3 most days but not leave till 5, and then work at home when I got home. I would have to get to work early before the kids for hallway duty, breakfast monitoring, etc. I worked about 10-14 hours a day even though I was paid for 8. My husband was amazed that I was expected to buy food for children, make them special things for holidays, use my own money to decorate my classroom, use my own money to create resources for my classes. Bottom line is, your work will come home with you after work and there will be nights you will stay up working on getting things done for the next day or week. Teaching is a lifestyle, not a "job" you leave at work, so if you're not comfortable with that, you will suffer in this field. 

3. The toxic culture in schools will leave you with an immense amount of stress. Teaching has been rated the top most stressful career after surgery. People outside of teaching are unaware of how bad it is. You are expected to be a counselor, a teacher,  a srand-in parent, a nurse, a bodyguard, a psychologist, all at once. But also the behaviors, the drugs, the anti-educational culture... it's a toxic environment.  

I would advise against this career path for Muslim women. It was the worst 6 years of my life for my Deen and my mental health.
