If you are interested in becoming an ESOL teacher, many states allow you to take the praxis exam and then use that to add on to your teaching licence. This weekend my husband went to a workshop and was very impressed with the information he learned from the review session. He had been searching for review materials and not finding anything so just wanted to put the word out that this training was helpful.
Probably the biggest piece of information he realized is that the test has been updated and the linguistic section removed. I remember that being the most challenging section so that was good news.
It looks like the trainings are offered around the country but not very frequently in any one city.
