Additional training was a joke--after teaching for a year, we had a 6 hour course on something...don't even remember. But New York State did require that I become a certified private school teacher or some such title. The company I worked for handled all the paper work, all I did was provide them with my background work experience and attend above mentioned class.
I loved teaching for the most part...it was a little difficult because the company I was working for were a bunch of money grubbers and would admit anyone who had a few bucks (or they could approve a loan for), including those who spoke no more than 10 words of English, a few who had active drug problems, those who had failed their GED test quite a few times. But for each 20 student class, you have a good 2-5 who were really serious about learning and advancing their careers (these are the ones you come to work for...they challenge you with their questions, eat up what you teach, do above and beyond what's asked, show up on time every day, appreciate your job...), and a majority who are just going because they're sick of working at Taco Bell or living with mom and dad and see this as a way to do something. Then like I said, you have some bad apples or those who are just impossible to teach.
The pay was $20 to start and I taught nights-6p-10p with 45 total minutes of break time, mon-thurs. I also had the opportunity to get extra money subbing for day classes once per diem and coming in an hour early for students who needed to make up hours.
You just have to keep up on the records-submitting grades on time, keeping track of papers and tests, making up tests and projects, attendance records, all that jazz. And you can't play favorites...no matter how fair a person you are, it's so hard not to, when you have one student who comes in 15 minutes late, didn't do her homework, leaves every 45 min to smoke, gets a 30 on the test and refuses to go to any study sessions or listen to why she got questions wrong...then you have another student who gets there before you do to familiarize herself with the anatomy models, who offers to tudor the previous student during her meal break, who gets a 96 and wants to know why--takes notes when you explain it and gets it right the 1st time..who busts her butt even though she's a single mother with a hard past...
I ramble, lol. It was a job I liked, and hated sometimes, and I kinda miss it. I'm an RN now with no time to teach, but I do plan on teaching once I get my masters (CNM).
Best of Luck,
