Choosing a Spanish school in Mexico

From an article on MexConnect:

The reasons to learn a foreign language are many. "For those of us traveling or living in Mexico, there is no doubt that learning Spanish enriches our lives," says Ohio native Anne Meyer, a social studies teacher.

Spanish differs from region to region, so studying Spanish in Mexico gave her advantage for retiring in the Lake Chapala area, where she plans to move in a few more years. But language schools abound. Which one do you choose? And how?

Ask questions
First of all, you want to make sure the school and staff are qualified. For example,

How long has this school been in business?
With what professional organizations is it affiliated?
Has it been approved by any official government entity?
Is the staff highly qualified? For example, do teachers hold a university degree?
Can you obtain college credit for your efforts?
Do you have access to a media lab? The Internet?
Also important are your own needs. You'll learn best when there's a good fit.

Are there specific courses available to suit your needs, budget, and interests? Are the Spanish courses designed for you to use the language on a daily basis? Is there a home-stay program for total immersion?

Finally, how much does it cost and what is included in the price?

Does your Spanish course include conversation classes?
What is the cost of living for a week or a month while you study?
Does the school organize tours? Are they included or charged separately?
Are there specials available where you can save money?
