About Us


The Arizon Group was founded by Dr Sokhaeng Chea in 1996 and its numerous centres of learning both in and outside Phnom Penh have been known variously as New York City Center, New York Institute and then New York International School since 2004.

The current campus was founded in 2008 and was renamed Grand Mount International School in 2016.

The new branding signified the intention to offer a quality 3-18 delivery of  both the Khmer National and International Curricular.   From 2019-20 this will include the transition to the UK’s Early Years Foundation Stage for preschoolers, and adoption of  Cambridge International Primary  & Secondary, leading to world-renown IGCSE – or International Certificate in General Secondary Education –  currently the world’s most popular university foundation course entrance qualification for 16-17 year olds.

We are already a registered Cambridge English Language Exam Preparation Centre, meaning our students can be entered for the range of globally respected qualification exams such as Starters, Movers, Flyers, Key and Preliminary -which are all to the same format as IELTS, or International English Language Testing System, the world’s number one English Language Test of English for  university entrance – and even immigration in some countries.

You will often read very vague, general and prosaic aims described on many international school websites, but not here. It is our  intention that the children at this school succeed foremost academically as evidenced by the grades achieved in externally set examinations. Why? Because that is primarily what most parents want and invest in.

Although it is true that many of the world’s most accomplished entrepreneurs, entertainers and even political leaders have attained their status with little or no academic foundation, the statistics reveal that they are in such a small minority that,  rightly or wrongly, it is still the grade on a certificate that counts for most of us, long term.

So with that reality check in our minds first we are then freed up to look at all the fun, creative, imaginative and effective ways we can use to secure the grades that open the doors.

One way we can achieve this nowadays is by increased use of on-line resources,  accessed outside the classroom  as preparation for in-class assessment and feedback – our parent community will become increasingly familiar with such apps as Class Dojo, Edmodo and Google Classroom.

Naturally there is still the vital need for all schools to offer a broad foundation,  and to balance our focus on the academic and vocational we have expanded our enrichment and extra-curricular programme to develop student interest, aptitude and talent in several new activities and we can boast notable achievement in both community service and inter-school competition, as this website shows.

Clearly we are primarily interested in nurturing winners, but we hope too that the simple values as exemplified by our thoughtfully recruited teaching and support staff – honesty, hard work, courtesy, respect, empathy and kindness, as well as a sense of humour-  will presage a healthy and happy tomorrow not just for our learners but all whom they come into contact with.

So all that said, why not join us?
