To become an online English teacher in the Philippines, you generally need a bachelor's degree, preferably in education or a related field. Many companies also require you to have a TEFL or TESOL certification, which is helpful for teaching English as a foreign language. Experience in teaching or tutoring can be an advantage, but not all platforms require it. It's best to check the specific requirements of the online teaching company you're interested in, as they can vary. Consider visiting official job listings for the most accurate information.
