If you're a teacher and want to get into information security, first, do not take any college-level courses.
If you Google my name you'll see that I've written a number of articles for the Military Cyber Professional Association, hacking9, and Substack. Almost all these courses deal with information security at some level. I've also spoken at a number of hacker conferences Defcon, Hope, and at a number of underground conferences. I'm more than qualified to guide you in what you should do.
The best program to get into computer security without a doubt is the Google Security certificate. You have to pass their test, but the course is only $300. You will learn enough of the basics to be productive understand security at more than a beginner's level and be proficient at writing scripts in Python. This will enable you to write code to analyze and search computer logs. You will also develop some level of expertise in Linux. There are a number of reviews out there about the Google certification. If you're going to ask why is it so cheap, because it was basically put together by people actually know what they're doing. Also, the hidden reason is that the more people in the field the lower they can make can make the pay scale. This Google program is a start and can be completed in 6 months or less. What about college-level courses?
Colleges today are basically diploma Mills and they want to get your money. They charge you an outrageous amount of tuition where in many cases you're taught by an adjunct who is making minimum wage when you figure it out and maybe on food stamps. If you find this hard to believe look on YouTube and do a search on adjuncts. A rational question to ask is if you're paying thousands of dollars for courses and the adjunct is only making about $4,000 teaching this course for a semester what's wrong with this picture? Colleges were not always this way, they were not always profit centers but that's the way they became. What about the professors at the colleges who teach these courses?
Some of them may have actual background and information security or worked in Private Industry but most of them came up through the academic ranks. A number of colleges publish information or pamphlets on their security program that you can make hundreds of thousands of dollars and these programs are well respected In Academia. The one thing they won't show you is the actual statistics of how many people go through the program and how many people make money in the security field. Many of these full professors, associate, or assistant professors would like to have a job in Private Industry at Google, Amazon, or Microsoft.
At one time I did aspire to be a teacher and then I got sidetracked and got into Information Technology about 40 years ago. yes, I'm that old but I also had to learn continuously because technology has changed. 40 years ago we did not have digital certificates of authority. These are digital devices that protect your data and it's something that you have to learn. You should read up On the encryption methodology called RSA. In short, RSA is The invention of asymmetrical encryption. What that means is that you encrypt with a key and you decrypt with another key that's a public key. You distribute this key to the individuals or websites that want to receive your information so they know it came from you. This RSA technology is what protects most internet activity and information transfer today.
At one time teaching in the United States was a Noble field. But this is no longer the case. the students in most cases are disrespectful and the parents are just another class of students. Another problem with teaching is the problem of wokeness which is political indoctrination. I invite you to read the book ”GANG OF ONE Memoirs of a Red Guard” This book was written by a Chinese student who grew up during the cultural revolution in China. You'll see the great similarities between what happens today in schools and what happened during the Chinese Cultural Revolution. If this does not convince you of the problem of political indoctrination or wokeness in our schools I have no idea what will.
I don't need to go through the syllabus of the Google security certificate, it's out there for you to read. I think the first month is only $49. You will still have to think about other courses and certificates to take. But at this point, if I had a choice between hiring somebody with a BA in computer science and somebody with a Google security certificate I would go with somebody with a Google security certificate. It's not a case that somebody with a computer science Bachelor won't be able to do the work, but someone with a security certificate may just have a better attitude and work ethic than somebody with a bachelor's degree.

Good luck God bless you, I know you have bills to pay but this may be a good start to get out of teaching.
