The Trinity CertPT with Lexical Lab

We are now offering the Trinity CertPT as part of our teacher development provision. In this post, we’ll be looking at what the CertPT is and how it fits with our programmes.

What is the Trinity CertPT?

The Trinity CertPT is a way to provide assessment and accreditation for teachers’ ongoing professional development. The PT stands for practising teachers and is, therefore, aimed at teachers who have two years’ language teaching experience or an initial training certificate with a national or international provider + 6 months’ teaching experience. The qualification is based on 100 hours total study time including 30 guided hours of learning and four assessment tasks on practical elements of teaching. It offers a level 6 qualification on OFQUAL’s scale between a Trinity Cert TESOL / CELTA (level 5) and a Trinity DIploma TESOL / DELTA / MA TESOL (Level 7).

How is the Trinity CertPT assessed?

To gain the qualification, teachers do four tasks which are set by Trinity. Lexical Lab provides support to do the assessments and marks them, before submitting the assessments to Trinity for moderation. Each task is up to 1000 words long (plus appendixes of material where required).

What are the tasks?

1: Asks you to evaluate a resource for teaching in terms of its underlying principles and its appropriacy for your students in your context.

2: Gets you to look at another piece of material or task and explain how you would use and adapt it, to get the greatest benefit for your particular students.

3: You produce your own material or lesson sequence for your students. You then explain your choices with reference to your context

4: Finally, you actually teach one of the sessions you planned for in task 2 or 3, report on how it went, why and explain any potential changes you would make.

How does the Trinity CertPT fit into our programme?

We started Lexical Lab in 2014, when we left the University of Westminster, to develop courses and deliver training workshops . Since then we have worked with hundreds of teachers from all over the world in varying contexts.

Our approach has always been a very practical one for practising teachers who are typically using published course material and at times developing their own lessons for their particular students. We ground our approach in very clear principles and explain how different coursebooks work and fit (or not) with those principles. That allows teachers to see where coursebooks work less well and how they can add value as teachers. Our insights come from being insiders to the writing and publishing process as well as practising teachers ourselves.

In other words, we are already providing the input for the Trinity CertPT assessments. We therefore see it as a great fit and the perfect opportunity to provide an international accreditation for our training.
