I need a TEFL / CELTA-certified English teacher who can run online classes for adults at every proficiency level, from complete beginners to advanced speakers. Each session should weave together the four core skills—speaking, writing, listening and reading—so learners build balanced competence rather than focusing on conversation alone. Scope of work • Design a flexible syllabus that can be adapted for mixed-ability groups. • Prepare engaging, level-appropriate materials (authentic articles, audio clips, role-play tasks, etc.). • Teach live via Zoom or a similar platform two to three times per week. • Provide concise written feedback after each lesson, highlighting strengths and clear next steps. Acceptance criteria 1. Lesson plans align with stated goals for all four skills. 2. Materials are shared at least 24 hours before class. 3. Feedback notes are delivered within 12 hours after each session. When you reply, include a brief outline of how you structure a 60-minute class to cover all four abilities and attach one sample activity you have used successfully with adult learners.
