What makes English good enough for customer support?
| Criterion | What to listen or look for |
|---|---|
| Clarity | Easy to understand on a phone line, at normal speed |
| Comprehension | Understands fast or accented speech and unusual phrasing |
| Fluency | Speaks without long pauses or searching for words |
| Professional tone | Polite, warm and confident, not scripted |
| Accuracy in writing | Correct grammar, natural phrasing, right register |
Does a neutral accent matter?
Customers care most about being understood quickly and feeling listened to. A light accent is rarely a problem when speech is clear and the agent understands them. Assess clarity and comprehension on a real phone line rather than judging accent on its own.
Which level do different roles need?
- Phone support and sales: strong spoken fluency and listening, typically C1 or higher on the CEFR scale
- Live chat: fast, accurate writing and the right tone, typically C1
- Email and tickets: accurate writing, with time to check, typically B2 to C1
- Back office: reading comprehension and accurate data handling; spoken level matters less

- Listen to candidate samples, and join final interviews if you wish
- Give feedback on the first hires so the bar is calibrated
How does English keep improving after hiring?
Quality reviews include language feedback, and coaching sessions use real conversations. Agents build product vocabulary and phrasing that fit your brand, and team leads share examples of strong replies. Language quality is tracked alongside process quality in the scorecard.
