This is the indispensable handbook to accompany your TESOL career path, whether you are studying, working, volunteering, or considering your professional options. Designed to be used by pre-service and in-service TESOL practitioners in the United States and Canada, it is the essential framework for developing your knowledge and practical skills in three core areas: The English language, research in second language acquisition, and the design and implementation of contextualized English language instruction and assessment. An ideal companion for both academic study and professional experience, this reference book provides you with:

- Foundations: the basics of what every TESOL practitioner needs to know about teaching, learning, and assessing English in a multilingual, multimodal world
- Opportunities: options for working with different English learner populations and hands-on classroom activities
- Perspectives: novice and experienced teacher voices alongside English learner voices throughout, balancing contemporary research findings with authentic case studies and vignettes
- Examples: high-quality lesson plans, learner language samples, assessment tasks, and reflective teaching prompts with supplementary resources to explore
- Guidance: clear and accessible information written by TESOL professionals for the global TESOL community

The book is divided into eight parts that can be integrated into various models of academic study or professional development: Foundations of TESOL, the English Language, Sources of Academic and Professional Learning, Research into Acquiring English, Building EAL Teacher Competencies, Instructional Design, Assessing EAL Proficiency, and Professional Pathways. A fully resourced online companion website also houses lesson plans, teaching portfolios, sample work, and extra teaching notes to account for the nuance and complexity of every learning and teaching situation.
