Why Choose ISI Dublin?

At ISI we been have teaching the English language to students from all over the world for almost 20 years at our two centres in Dublin’s city centre. Our new online courses delivered by the same team of dedicated and professional teachers, aim to recreate the renowned ISI classroom environment, using our live online platform and our eLibary technology.

Award-Winning School

Academic excellence is at the heart of what we do. ISI Dublin has won the English Language School Europe Award three times, in 2014, 2016 and 2018 (and has been nominated every year since 2012).


The school is recognised by ACELS, a service of Quality and Qualifications Ireland, for English language education. We are also an offical exam centre for the Trinity College London ISE Examinations and a recognised examination preparation centre for the Cambridge Examinations and IELTS.

Small Groups

The average online class size at ISI is 12 students. This means that teachers can focus more on the needs of individual students and tailor lesson plans to suit their needs.

Individual Assessment

All students are individually assessed at the time of booking through an online test. Progress is recorded weekly to ensure students are studying at the correct level. When a student can complete all the tasks in their level with some proficiency, they may be moved to the next level.

Level specific

With high student numbers year-round, ISI can offer up to 16 different online levels throughout the year. For example, this means that we don’t just offer one B1 class. We may have two or three B1 classes, all of slightly different abilities, allowing for very precise level placements.

Nationality Mix

ISI offers a very good nationality mix, with up to 40 different nationalities studying in the school at any given time. This allows students to practise their English with students from other countries.

Value for money

We are a medium-priced school, offering courses to suit all budgets.

Innovative Approach

ISI teaches the language which students need to communicate in ‘real life’ and for this reason we use an innovative and communicative approach. While there is a core online text, teachers also incorporate the use of ‘real life’ materials, such as online news, videos, music and a full suite of dedicated EFL educational software.

High-quality teaching

All our teachers are university graduates with a government-recognized teaching qualification. Most have several years’ experience teaching in Ireland and abroad. Our Academic Management team monitors online teaching standards through teacher observations, weekly teacher meetings and regular teacher-training workshops, where teachers can share ideas and develop new skills.
