Generally, ESL teachers working in international schools tend to receive higher salaries compared to those teaching in public schools or private language centers. This is primarily because international schools often have larger budgets, offer more competitive compensation packages, and seek qualified teachers with specialized skills. On average, ESL teachers in international schools can earn a median annual salary of around $64,000, though this figure can vary depending on the country, level of experience, and qualifications. Additionally, international school positions often include benefits such as housing allowances, health insurance, and professional development opportunities, which can further enhance the overall compensation package. Therefore, while ESL teachers in international settings may earn more, the exact salary depends on various factors including location, experience, and the institution's resources.
