First of all, it is advisable to dwell on the country's legislative norms regarding the observance of compulsory school uniform in society. According to article 22 of the Constitution of the Republic of Kazakhstan, “everyone has the right to freedom of conscience”. At the same time, as spelled out in this article, "the exercise of the right to freedom of conscience should not condition or restrict human and civil rights and obligations to the state."
Relying on constitutional and other legislative norms, the Law "On Education" defines the appropriate legal relations in this area. In particular, Articles 47 and 49 of the Law “On Education” stipulate compulsory observance of school uniform by students and the obligation of parents to ensure compliance with school uniform.
In this regard, the Order of the Minister of Education and Science of the Republic of Kazakhstan dated January 14, 2016 "On the requirements for compulsory school uniform in secondary educational institutions" was developed in accordance with the norms of the current legislation.
Therefore, this is not a violation of the rights of believers.
