The aim of the thesis is to compare the educational systems of two European states with different state institutions, history and current political-historical situation. The work will be of comparative character and will be based mainly on the work with the studied literature. The work will use both Czech and Spanish literature. The main benchmarking tool will be the International Standard Classification of Education at ISCED 2011. In the practical part, this classification will be applied to both education systems, and at the end of each level of education there will be comparisons. The result will be a simultaneous evaluation and comparison of the education system of the Kingdom of Spain and the Czech Republic.
