Teacher
If you are looking for routine and stability for your child, this is not the school for you as it is a revolving door of teachers, students, admin, lawyers, and maintenance staff. People are constantly coming and going at all times of the year so there is never a firm routine for children. Students might be assigned a room at the start of the year but are frequently moved around due to testing and other events. Constant schedule changes interrupt routines but students need a routine to feel safe and secure. This school was built with small class sizes in mind but in the past few years, more and more students are crammed into classrooms that have not expanded in size so everything is cramped. This also means teachers have very little time to spend with each student individually.
Resources are either outdated and/or limited. For example, not much of a library exists and the few books that remain are either outdated or irrelevant to most if not all students. Also, there is a chance a student might be given a photocopy of a textbook rather than the original for some of their classes.
Upper management is either uncaring and/or impossible to reach for most teachers, though one higher-up, in particular, does give their personal number out to a few select teachers they deem as their favorite, so there is no equitable treatment of staff. If they don't care about you, you might as well be invisible. It does not create a healthy work environment and many teacher voices are not heard or respected. Even with students, several have left due to unaddressed bullying.
Management is under-qualified and ineffective in creating an atmosphere where students feel encouraged to follow typical codes of decorum. For example, there was a huge issue with students yelling racial swears and drawing derogatory and/or hateful symbols and punching/damaging the walls and this was an ongoing issue all year. Teachers did the best within the confines of their authority regarding this issue but no serious consequences were ever given for even the most egregious violations.
In the end, I believe most teachers are doing the best they can considering the situation. The students have potential but aren't placed in an environment conducive to learning. Despite being a small school, communication is disjointed, and hiring a liaison who can bridge the huge gap between upper management and ALL employees would be a step in the right direction. Rest assured, there are better options for your private school needs in Belgrade.
