First language maintenance
This is a specialist program implemented when there are significant students of the same home language who can function transactionally in the language of instruction. It requires the employment of a qualified bilingual teacher and a teacher aide come interpreter.
The students attend target language classes when regular students attend a second language program. They also attend special classes to accelerate their competency in the language of instruction. Usually, this coincides with the language classes of regular students.
Using interpreters or translators
The word, 'interpreter', applies to spoken language and 'translator' applies to written language. Interpreting and translating is a highly skilled position, requiring excellent interpersonal skills and confidentiality.
Interpreters are mediums for communication, not the people being communicated with. Always face and maintain eye contact with the person needing an interpreter and speak normally. Sitting in a triangular configuration facilitates this best.
