Errol Martin, one of our most experienced Computer Science teachers.

Expert subject knowledge with a proven track record of student success

Errol Martin B.A. Hons M.Sc P.G.C.E.

"I'm an experienced GCSE & A-level  teacher of Digital Technology, Computer Science, Software Systems Development tutor at Code Clock. I am passionate about all forms of technology and use it wherever possible in my lessons to enhance the learning experience.

With over 18 years of teaching experience, 15 of which as Head of IT, I've seen firsthand the transformative power of computer science and its potential to open doors to exciting careers. As an experienced Head of Department, and CCEA examiner, I possess a deep understanding of the curriculum and how to guide students towards success.

It's not all about exams. I believe in nurturing a love for learning that goes beyond the textbook. My experience working in the IT industry with Canon UK allows me to bridge the gap between theory and real-world applications, making lessons engaging and relevant.

I have a proven track record in getting the best results from my students, with students consistently achieving grades well above grammar school averages at both GCSE and A-level. Plus, in my role as Director of IT at Friends School Lisburn, I have guided our school robtics team to win the UK Schools First Tech Challenge,  the premier UK schools robotics competition."
