What is the difference between Teaching English as a second language and as a foreign language?

Question

Is there a difference in the test for the certificate? Where can I get some resources?

Answer 1

ESL or ESOL is teaching English to students whose native language is not English and they are in school in an English speaking country, taking courses in English. It is helping them to accomadate.
Teaching English as a foreign language would be done in a country where English is not the native language and the courses are not given in English.
There is a difference in the test and certificate.
Go to high school in a city and ask to interview a teacher of ESOL.Another source would be a college that offers ESL certification. English certification is needed for teaching English.
I just interviewed a student who came to the US from Korea 1& 1/2 years ago. She took English as a foreign language in Korea. I have spoken to teachers who spend a year in a foreign country teaching English. The student I interviewed for college took 1 1/2 months of ESL , there is a test to get out.

Answer 2

They're essentially the same thing. The same field is also called "Teaching English to Speakers of Other Languages" and "Teaching English to English Language Learners".

"Teaching English as a Foreign Language" is the oldest name for this field. It was largely abandoned because "foreign" was felt to be a bad term. The other names are attempts to remove any stigmas.
