My Admissions Advisor told me I could waive 10 hours of my practicum with 10 teaching/tutoring/observation hours I’ve completed in the past. How does that work?

Teachers can apply 10 hours to their 20-hour practicum requirement from prior
experience that meets our practicum guidelines. This experience must have occurred
within the six months preceding your TEFL course start date. You will address it in the
write-up and provide contact information for someone who can verify those hours, just
like all other hours logged for the practicum requirement.
