The secondary education which serves as a bridge between primary and higher education is expected to prepare
   young learners between age group of 13 to 15 in the world of work and entry into higher education. The secondary
   education starts with classes from Grade 7 to Grade 9 leading to higher secondary classes from Grade 10 to Grade 12.

   The subjects are English Language, English Reading, International Studies, Maths, Science, Physical Education (P.E),
   Thai Language, Thai Career, Thai Maths, Thai Science and Thai Social. The students are also required to take the
   Cambridge Examination for Key English Test (KET) and Preliminary English Test (PET). This examination helps the
   students to be more enhanced and upgraded in terms of their English speaking abilities, reading and comprehension
   skills and Linguistics as well.

   Students coming to IBS have varied experiences in the area of Information Technology (IT). There is a computer lab
   with access to the internet. Each classroom has a set time once a week to work in the computer lab. With the help
   of the computer teacher, training is given to students to do Inquiry Projects, Research Projects, Power Point
   Presentations and how to use the internet efficiently. Our goal is to be able to have a bank of computers in every
   classroom which would be connected to the internet for immediate classroom research. We have been able to
   purchase digital cameras, digital movie cameras and some brand new computers for video production. We have
   also been able to replace some of the old computers with new ones.

   The teaching staffs consist of Native English Speakers from Great Britain, Australia, Canada, New Zealand, USA,
   and other English nations. There are also teachers from Asia who hold masters degree. All teaching staffs are
   specialized in their own field of education to be able to prepare the secondary students in achieving their goals
   in life.
