Message From The Education Consultant

The Oasis International School Curriculum is structured to enable students to reach their full potential in whatever occupational path they may choose, in whichever part of the world. The curriculum is diverse enough to enable students to select their subjects in line with individual interest, within a framework of course requirements.

I suppose true education goes beyond learning books. It is that which shapes one’s character, personality, value system, integrity and humility. Education is that what shapes tomorrow’s leaders.

Education, at its higher levels, is indispensable when it comes to developing wholly a student’s character and his humility. Character should be strong, full bodied and intense and humility ought to be sincere and open. Education should be paired with no other accessory than humility.

Learning never ends ‘until death do us part’. It is an infinite process that molds one and shapes one’s thinking processes. It is the potency of one’s course of thinking that would make one stand apart from the rest.

Gold has to be put to test by being scorched in flames before it is transformed into fine jewelry. The mind too would have to give into inferno before it is shaped into grandeur. That is why, I would claim that higher education is a requisite after formal schooling.

My greatest aspiration as the Education Consultant of Oasis International School is to get our students into eminent Universities of the world, like Harvard, and I would like to take the pleasure in wishing all our students the very best in their endeavors.

Message From The Student Counselor

I am very pleased to write this note to briefly explain my role as the school counselor of this school.

My activities in the school include professional counselling to the students, teachers, other staff members and parents whenever the need for counselling has been identified. In this international school within an urban community with a student population from different nationalities, complex situations are likely to arise that may need careful and cautious guidance. As the counselor I help the students to understand and overcome social, emotional and behavioural problems in the school and at home by providing individual as well as small group counselling sessions. I also work with students to help them develop skills such as time management, efficient work habits, decision making, problem solving and effective communication. There is a significant need to guide the students to aim for realistic career and academic goals and help them to develop practical support systems to succeed in their educational career.

My professional work in the school also involves providing counselling in particular situations such as substance abuse, school refusal and bullying at school. I also provide counselling to parents of the children attending the school helping them to improve their parenting skills so that they are able to better manage any day to day problems that they may encounter in bringing up their children. Lastly, I would also be available to listen to the students, parents and the teachers whenever it is necessary to provide them with emotional support and help to overcome any difficulties recognized by them so that they will be able to achieve their educational objectives and goals.
