I'm tutoring a very bright 15-year old Korean student who just arrived in the U.S. a few short weeks ago. While they are catching on VERY quickly, their proficiency currently appears to be at an Intermediate level.
Q. 1) What are some good placement tests?
Q. 2) What are some good textbooks that others have had a good experience with in this kind of situation?
I can certainly tell that this is going to be quite different from my previous experience teaching
ESL, when I taught semi-literate migrant farm workers in groups of 3-6.
