TEFL vs TESOL vs CELTA: which should you choose?
TEFL and TESOL are general terms for English-teaching certificates, offered by many providers, usually 120 hours or more and often online. CELTA is a specific Cambridge English qualification with at least 120 hours and assessed teaching practice with real learners; it costs more and is more intensive. For online and most overseas language-school jobs, a 120-hour TEFL/TESOL is usually enough.

Common questions
Is CELTA better than TEFL?
CELTA is more intensive and includes assessed teaching practice, so it carries more weight with some employers. It is not necessary for many online and language-school jobs.
Can I do CELTA after TEFL?
Yes. Many teachers start with TEFL, gain experience, and take CELTA or a diploma later.
Is TESOL the same as TEFL?
In practice yes, for certificates of the same hours; TESOL is the broader term.
