Pros
1. flexible schedule -- you work no more than you want to work. 2. good pay -- once you are hired, you make good money for teaching, $14 an hour for cross-training (learning to teach another subject), and $10 an hour for anything else you need to do, plus mileage, when you have to drive more than 30 miles round-trip. You don't need to do much, though, as once you prep your materials, you can teach or tutor out of them at a moment's notice. 3. You can be proud of the company you're working for. What we teach works, so you don't have to feel like you're not giving your students good advice. 4. It makes you feel smarter. You learn to think on your feet. You get a different view of teaching than you get from universities and community colleges. And, of course, you improve your own testing abilities. 5. You can make money proctoring tests. 6. You can get teaching work, if that's relevant to your career field, rather than having to wait tables or something, so you won't have gaps on your resume. 7. You can often get into the classroom very quickly once you're hired and start getting that paycheck.
Cons
1. You might get less work than you want, especially in the summer. 2. It is intensive and unremunerative up-front. You have to do a lot of prep to get through your first training, and that time is unpaid. 3. Every time a new version of a book comes out, you have to prep it again (although you are paid for your time, up to a predesignated point). 4. To advance to a Master or Premier tutor, you have to bring in your own business. You have to be a salesman. 5. Raises are largely based on student evaluations, and even then are pretty small. 6. No benefits unless you're full-time, which most teachers aren't. 7. High turnover. 8. You are often helping rich kids get higher scores, when they're not necessarily the ones who most need or deserve help.
