The Trinity College London DipTESOL is an advanced teacher training programme for experienced English language teachers who wish to deepen their professional expertise and gain an internationally recognised TESOL diploma.

EdSkills Academy, in collaboration with ALS Education London, offers the DipTESOL as a rigorous, academically grounded programme that combines theory, research, and practice. The course is designed to enhance teaching effectiveness, develop advanced pedagogical and assessment skills, and support teachers seeking senior roles in English language education.

The DipTESOL is a Level 7 qualification (UK Ofqual), equivalent to the Cambridge DELTA, and is recognised worldwide by educational institutions, language schools, and universities.

Through this collaboration, EdSkills Academy provides a comprehensive learning environment that prioritises academic support, reflective practice, and professional development. Participants benefit from expert guidance, structured mentoring, and sustained support throughout the course, ensuring meaningful engagement with both theory and classroom practice.

Our aim is not only certification, but long-term professional growth.

While academic achievement represents just one dimension of a student's overall profile, it is often disproportionately emphasised in traditional admissions processes. At Applied Language Studies House, we adopt a more holistic approach, selecting candidates based on indicators of future potential—such as intellectual curiosity, resilience in the face of challenges, and creative thinking.
