If you plan to teach online only: 120-hour online TEFL from reputable provider (Premier TEFL, i-to-i basic) is sufficient. Platforms care you have certification, not which specific one.

If you might teach abroad: CELTA or ITA with practicum component. Many schools want to see hands-on experience.

If you're building long-term career: CELTA is investment in yourself that pays dividends through better jobs and confidence.

If you're on tight budget: Premier TEFL or similar budget option. Better to have affordable certification than no certification.

If you want to specialize: i-to-i or courses offering specific specializations (Young Learners, Business English)

• Promises of "accreditation" without details: No global accrediting body for TEFL exists. UK, US have various private accreditors but none is official requirement.
• Extremely cheap (under $50) for 120 hours: Often just pdfs with no support or quality content
• No contact information: Legitimate courses have real addresses and phone numbers
• Guaranteed job placement: No course can guarantee this. Assistance yes, guarantee no.
• Completion in under 2 weeks: 120 meaningful hours requires more time
• Aggressive upselling: Good programs stand on merit, don't need hard sales tactics

• Teaching Young Learners: If teaching children online (VIPKid, QKids, etc.) - specialized course helps tremendously
• Business English: Adds credibility for corporate clients willing to pay premium
• IELTS Teacher Training: Lucrative specialization, students pay well for exam prep
• Teaching Online Certificate: Focuses on virtual classroom management and technology

Some companies offer "free" TEFL upon hire:

Examples: VIPKid (offered to applicants), some Chinese companies

Pros: Free, immediate job placement

Cons: Only recognized by that company, minimal actual training, locks you into their platform

Verdict: Take it if already hired there, but don't rely on it as your only certification. Get proper TEFL for flexibility and career options.

CELTA at $2,000 vs Premier TEFL at $200:

CELTA opens higher-paying jobs ($20-30/hour) vs standard jobs ($12-18/hour). Difference of ~$8/hour.

Break-even point: $1,800 cost difference ÷ $8/hour premium = 225 teaching hours

At 20 hours/week teaching, you recoup investment in ~3 months.

Plus intangibles: Confidence from quality training, better prepared for classroom challenges, networking with classmates and centers

Bottom line: If you can afford it and commit the time, CELTA pays for itself quickly.
