Brigid Nugent – Delta Modules Tutor 

Brigid (Nugent) is Irish but since her postgraduate years, has lived, worked, stayed in more countries than she can enumerate.

She holds a Masters in TEFLA from Aston University and became a DELTA tutor, shortly afterwards in 1996, a CELTA tutor in 2000 and an assessor for both in that same year.

For 20 years, she was in charge of the Cambridge examination speaking components and the training up of 15 team leaders, who trained examiners in a number of countries that stretched from Greece and the Mediterranean to Central Asia and parts of North Africa. She was an IELTS trainer and examiner for many of those years. After retiring from that work in 2016 and leaving Turkey, her base for many years, she moved to Italy and became a Joint Chief Assessor for the Cambridge Teaching Qualification Awards, for most of the same countries.

She has been a freelance teacher developer and trainer for most of her professional life in South and Central America, In the Far East, the Middle East and the Near East, as well as in North Africa (and these include exotic places like Mauritius, Ethiopia and Costa Rica – all three countries where she has left her heart and many wonderful colleagues, trainees and students). She has coordinated EMI courses in Chinese Universities (English as a Medium of Instruction), she has conducted numerous teacher development courses, Young learner courses, TKT courses, she has helped set up centres and trained trainers – the normal CV of most freelance trainers.

Her real passion lies in the face to face classroom, with her learners, with her trainees, with her peers, with her colleagues, for her belief is that without passion and kindness and a craving to share that passion with others, good teaching and real learning cannot  take place.

Her own marvellously kind Delta tutor taught her that, she says and the best trainers that she has worked with, have always helped to uphold that belief.
