Job Sites for Teaching Online High School Courses?

Hi all,

This post is for my sister-in-law who is possibly looking to teach online high school courses in Spanish and/or Education. She has a Master's in International Education and is ABD w/ her doctorate in the same subject. She's also working on a Master's in Spanish (busy lady). Anyway, she is currently teaching high school Spanish. I'd like to help her find some online teaching opportunities to supplement her income. I'm much more familiar with DL at the college/university level. That said, I would greatly appreciate any online high school job sites and/or listings of the largest online high schools to pass along to her.

Thanks!
