The school has about 1750 students who are divided into 73 classes.There are 132 teachers,37 people who belong to the personnel department and 9 laboratory technicians. Students come from different cultural and economic situations, for this reason it is necessary to adopt some teaching methods which can develop the integration and inclusion of them.

It will be important the European value which comes from the experiences with foreign teachers who we could start to work with on future .
