If MSc in Child Development is an eligible degree for the post of educational counsellor in schools then there should not be rejection until unless the candidate is not up to the mark as per the expectation of the school administration.
Have you done the preparation for exam for selection of school counsellor properly, understanding what is the purpose of the school counsellor and what are his main functions in the school environment. If yes, you can skip the next paragraph where I have mentioned about it in brief. Otherwise you can go through it and elaborate on these basic premises and prepare again for the exam for the post of school counsellor.
School counsellor is a person who has got the prime responsibility of guiding the students in proper direction and help them to fight their resistances and apprehension about the schooling. This is not only a psychological type of counselling but requires a lot of common sense and ability to handle and channelise the soft minds of students in positive directions. During schooling a child grows into adolescence and this is the crucial time when the personality takes shape in a particular path. This is the time of making friends, developing relationships and to make preliminary decisions about the career in the coming life. Students will face a number of problems in mitigating the challenges in their school life and some of them get stress due to this. it is the tender age and they have to start bothering for friendship, studies, competition, extracurricular activities and other things like that. A school counsellor has many jobs and responsibilities to take care. His main job is to assess the potential of the student as well as find out his weaknesses and strengths so that he can be motivated or aligned in a particular direction where his interests meet his career and he can finally become a productive member of the society. The counsellor has to interact not only with the particular student but has to be in regular contact with the parents and school administration. His job is much wider than the other employees of the school. These things are to be understood well by the aspirants who want to become a counsellor and are to be reflected in their interview taken by the school management.
