WBCHSE EVS Question Paper 2019
The State of West Bengal is one of the first in India where the modern system of education was established by British Missionaries. Since then, it has evolved into the fine education system and is now monitored by state run autonomous body.
The West Bengal Council of Higher Secondary Education (WBCHSE) came into existence in 1975. It is an autonomous examining authority. It is responsible for conducting examinations for standard XII for both government and private schools affiliated to this board. It is responsible for improvement and promotion of education in the state.
The WBCHSE has made a sustained effort towards a quality uniform evaluation system all over the state of West Bengal. More than 6800 schools and over 16 lakhs students are being monitored by the Council. The task has been more challenging in context of the very competitive global environment and a diverse range of subjects.
The H.S. education is a significant part of the overall education system. West Bengal has the distinction of being the pioneer in the modern education system by virtue of the influence of the great literary and social path finders.
