I think it varies by organization.
In our organization, we have over 20 Arabic-speaking workers, and we have added volunteer interpreters to supplement that work. I think it becomes more of a challenge in smaller communities where they may not have the Arabic-speaking settlement workers.
The only other piece, again, is with that large influx of refugees over a very short period of time, there was an increased need for Arabic speakers.
I think agencies did what they could to upscale. They used volunteers if needed, and used their in-house people as well.
