There is a large population of Indians in Dubai, Sharjah (both in UAE) as well as Saudi Arabia. Choosing a school is a critical issue. This post is for those who prefer to put their kids into schools aligned with the Indian system.
Saudi Arabia does have CBSE schools. You may find them in this list. Do check the CBSE website for more. CBSE also has schools in the United Arab Emirates, Kuwait, Bahrain, Nepal, Singapore, Qatar, Oman, Nepal, Bangladesh etc. Many of those schools have excellent academic standards as is reflected in this CBSE 2016 performance tabulation. GEMS and JSS are well regarded groups running CISCE and CBSE schools in Dubai.
Here is the performance of some of the CBSE schools in Dubai in the class 12 examinations of 2016.
Here is the performance of some of the CBSE schools in Sharjah in the class 12 examinations of 2016.
The Council for the Indian School Certificate examinations has a few affiliated schools in the United Arab Emirates (UAE) - Dubai and Sharjah. In 2012, the Class 12 ISC Topper was from Dubai Modern Academy (GEMS) after which he headed to Stanford.
Both the CBSE and the ISC are well respected systems, though if you're in a transferable job, the sheer scale of the CBSE system and their large network of schools, makes it easier to find a school in another country, or on your return back to India. The CISCE has just a few schools outside the country and a much smaller number of schools than CBSE, within India itself. However, in most large cities, other than Delhi, the CISCE schools typically dominate the lists of best or preferred schools. This holds true in Mumbai, Bangalore, Pune, Kolkata and even to some extent, Hyderabad and Chennai. Same for Lucknow and Dehradun.
At the grade 11-12 level, the syllabus of both boards is well aligned with that of competitive examinations in India. However, till Class 10, the ICSE system is considered more rigorous, has significantly more focus on practical and project work, and the English curriculum is far better than that of the CBSE. The ICSE system is often a good mid-point between the usual Indian system (CBSE) and the hands-on foreign systems (IGCSE, A-levels) but it also has a fair bit of work load in middle school.
For IIT JEE and other entrance examinations, there is a large variety of online material available nowadays. Location and physical coaching in a brick and mortar environment is no longer necessary.
Schools affiliated to the Kerala board are also present in the gulf countries. They cater to the large malayali population in the gulf countries and the middle east.
For candidates aspiring to pursue higher studies in the United States or England, after grade 12, the CBSE and ISC systems are better recognized than the local Kerala Board, in North America and Europe. Taking the SAT and TOEFL is generally required for entering undergrad programs in the United States. Often, applications do get a significant boost, if candidates take the AP examinations or Subject SAT tests. Medals won in International Olympiads significantly boost us chances, but naturally, this is a rare achievement. There are some gaps but the Indian syllabus typically does cover most of what is present in the American Common Core or British GCSE/GCE, so there isn't too much of a shock when a student from the Indian system moves to the USA or UK or Canada for undergrad.
These are the names and addresses of some CBSE schools in Kuwait. However, academic performance data is not available for them.
