Please help me talk some sense into my sister!

[bluebooger]

would your sister be interested in teaching English as Second Language ?

this is one of the most reputable sites for information on teaching ESL

Job Discussion Forums :: Index

Dave's ESL Cafe International Job Board - International Job Board

The ESL Job Center

they have lots of people with knowledge of teaching ESL in Japan, Korea, China, Africa, South America, Dominican Republic, Mexico, Spain

they don't supply jobs, they are not a job broker
they are just people who have done ESL and comment on it
(of course some schools and job brokers post on the job board)

of course there are other sites

Teach Abroad - Reviews of English Teaching Jobs Abroad

but I don't know know anything about them

I do know that a teaching degree is not required.
Any degree will do (a CELTA certificate is nice to have though CELTA (Certificate in Teaching English to Speakers of Other Languages) | Cambridge English )

Going abroad, traveling, teaching children might be something she'd be interested in.
Pay obviously isn't great, but housing or a housing stipend is usually included in the salary)

And maybe the experience will help motivate her or at least be something interesting she can put on her resume for her next insurance company application.
