Determining someone’s English skills is one of the most common problems I come across.
When I was in the Philippines last year I was given this awesome tip for one way to get a better idea.
Ask potential employees if they grew up watching “Sesame Street” or “Batibot.”
This is really clever, and surprisingly effective!

Ask your current employees what they grew up with and let me know in the comments if this was correct.
Just FYI, my guess is that this technique will become less and less effective over time as more and more Filipinos know what their answer should be (from this blog post).
