“All our teachers are certified.” It is the most common claim on children’s English platform websites, and the most widely misunderstood. The question is not whether any teacher on the platform holds a certificate. The question is whether a certificate is required from every teacher before they can teach, or whether some teachers are certified and others are described as “experienced” or “qualified” without a named credential.
The difference is significant. On a required-certification platform, every teacher you could be assigned to has met a stated minimum standard. On a preferred-certification or no-stated-standard platform, you may be assigned a teacher with no documented qualification depending on availability. This page explains how to tell which type of platform you are using.
Three platform types on teacher certification: what each means for parents
Three Types of Platform Certification Policy
• Required certification. The platform states a specific minimum qualification and applies it to every teacher. A teacher without that qualification cannot be listed. When a parent is assigned any teacher, that teacher meets the stated minimum. This is the most parent-protective standard.
• Preferred certification. The platform encourages teachers to hold certifications but does not require them. Some profiles will show a named certificate. Others will describe teachers as “experienced” or “skilled” without a credential. The parent cannot know from the assignment which type of teacher they received without checking individually.
• No stated standard. The platform uses language such as “expert tutors,” “passionate teachers,” or “qualified educators” without naming any specific credential. There is no way for a parent to verify what standard, if any, applies to any specific teacher.
How to Find Out Which Type Applies
The platform’s website marketing rarely tells you directly. These three steps produce a reliable answer.
• Step 1: Search the platform’s website for the words “required” and “qualification” together. If both appear in the teacher hiring section, read the surrounding text carefully. If only “preferred” or “experienced” appear, that is a signal.
• Step 2: Ask the support team directly. Use this exact question: “Is a specific English teaching certificate required for every teacher on your platform, and if so, which certificate?” A yes answer followed by a specific credential name is the only satisfactory response.
• Step 3: Look at 10 different teacher profiles on the platform. If the majority show no certificate name, the platform does not require certification regardless of what the marketing says.
What to Do Once You Know
| Platform type | What it means for you | Recommended action |
| Required certification, named standard | Every assigned teacher meets minimum standard | Verify the specific standard is meaningful (not 40-hour online course) |
| Preferred certification | Teacher quality is variable by assignment | Always check the specific teacher’s profile before lessons; request certified teachers explicitly |
| No stated standard | No independent verification possible from the profile | Take a trial lesson with direct teacher assessment; consider platforms with stated standards |
Where 51Talk Fits In
What 51Talk is
51Talk is a live one-on-one English platform for children with 25-minute structured sessions, qualified teachers, CEFR-aligned curricula, and teacher profiles accessible before booking. Platform details at 51talk.com.
How to verify 51Talk’s certification policy
Apply the three-step verification above to 51Talk before purchasing: check the website language, ask the support team directly, and browse teacher profiles. Ask specifically: is a named qualification required for every teacher, what is the minimum standard, and how is it verified? A platform of 51Talk’s scale has documented answers to these questions. Save the written response alongside your purchase confirmation.
What to keep in mind
Even on a platform with a stated required certification standard, the quality of the specific certificate matters. A required 40-hour online TEFL course is a stated standard, but it is a minimal one. Ask which specific qualification is required and verify that it involves assessed, observed teaching before concluding that the standard is meaningful.
Before You Enrol: Questions to Ask Any Platform
• Is a specific English teaching certificate required for every teacher on the platform? Not “all teachers are certified.” The word “required” matters.
• Which certificate is required, and who issues it? Name the credential and the issuing body.
• What proportion of the current teacher pool holds the required certification? If 100% is claimed, it should be verifiable from profiles.
• How is the certification requirement enforced for new teachers joining the platform? Process, not reassurance.
Frequently Asked Questions
Does 51Talk require all its teachers to hold a named English teaching certificate?
51Talk has a qualification and training requirement for teachers on its platform. Contact 51Talk’s support team before purchasing to confirm the specific qualification required, the issuing body, and how it is verified. Request written confirmation and check teacher profiles to confirm that the stated requirement is reflected in what is displayed. Visit 51talk.com to access current information.
What is the difference between “all teachers are certified” and “all teachers are required to be certified”?
“All teachers are certified” is a snapshot claim: at this moment, the teachers currently on the platform happen to be certified. “All teachers are required to be certified” is a structural claim: any teacher who joins in future must meet this standard before they can teach. Only the second provides ongoing assurance.
How do I check individual teacher profiles on a platform?
Look specifically for: the certificate name (CELTA, TEFL from a named provider, TESOL), the year obtained, and years of experience with children. If these three elements are absent from a majority of profiles, the platform does not require certified teachers regardless of its marketing.
Is it reasonable to request only certified teachers when booking lessons?
Yes. On any platform where certification is preferred rather than required, explicitly requesting a certified teacher when booking is a reasonable and straightforward ask. Ask the support team to confirm that the teacher assigned to your child’s trial holds a named certificate before the trial begins.
What if the platform claims all teachers are certified but the profiles do not show certificates?
This is a significant inconsistency. Raise it directly with the support team: “Your website states all teachers are certified. The profiles I reviewed show no certificate information. Can you explain this?” A satisfactory answer either clarifies a display limitation and provides the information directly, or reveals that the claim is aspirational rather than factual.
What to Do Next
Apply the three-step verification to any platform you are seriously considering. Ask the direct question about certification requirements and request a written answer. Browse 10 profiles and assess whether the stated standard appears in practice. Use the three-tier table above to decide what your next action should be. A platform that passes all three steps on a required, named, meaningful certification standard gives you the assurance that any teacher you encounter has met a documented baseline. That assurance is worth the 10 minutes it takes to verify.
