"Many people like you, who have been teachers and have years of experience, still get their TEFL Certification just so they can have that additional experience and credential."

Like you, I know I am qualified to get most jobs but still did the CELTA course. If only the employers who ask for TEFL certification at interview stage, paid us for having the training and certificate. As others have stated, I still feel you could get a job easily without the certification, based on your background and experience.

Good luck.
