No. Even though we’ve been rambling on about English this whole time, we also offer the same job in several languages: Arabic, English, German, Italian, Japanese, Mandarin, Portuguese, Spanish, and Russian, spreading the language love to French families in 9 languages.
The same idea applies to all of them, though: you need to be a native speaker in one of these languages in order to be an instructor for it (or bilingual or have a very advanced fluency) for the teaching process to work for the child.
