Long term English teachers can provide and plan a better curriculum for kids. Teaching is often a challenging as there are no permanent teachers in the school. What we do right now is, each volunteer has to take a note and to make sure what has been taught in the last few weeks, so the new coming volunteers won’t keep repeating the same things. However, what we really need are long-term English teachers. No matter 3 months, 6 month, even a year, would be really great and you will be a really positive impact for kids.
