The National Council of the Boy Scouts of America allows any Scout or Scouter who can demonstrate some basic proficiency requirements to wear the Interpreter Strip of that language. Here are the requirements from National:
Scouts and Scouters may wear this strip if they show their knowledge of a foreign language or the sign language for the hearing impaired by:
Carrying on a five-minute conversation in this language.
Translating a two-minute speech or address.
Writing a letter in the language (does not apply for sign language).
Translating 200 words from the written word.
While the Interpreter Strip is usually earned at the unit level unit leaders may be stumped in identifying a resource to evaluate the applicant's proficiency in language of interest. The International Committee is developing a database of people willing to help on this front. We have identified resources for a number of languages and look to expand on it. If you need a counselor to help evaluate an applicant for the Interpreter Strip or you want to be a counselor yourself please contact Michael Files (michael_files@yahoo.com).
The requirements for this award are detailed at the URL listed below.
