The post-war period was marked by numerous educational reforms: in 1947 the 7-year schooling period was introduced and it did not necessarily take place only in elementary schools, as after having completed 4 grades of elementary school the pupils had the option to continue the obligatory schooling at higher elementary schools, lower gymnasiums, middle class schools or the then (nonclassical) secondary modern schools.
Povojno obdobje so zaznamovale številne reforme šolskega sistema: leta 1946 je bilo uzakonjeno obvezno sedemletno šolanje, ki pa ni nujno potekalo samo v osnovni šoli, saj so imeli učenci po končanem 4. razredu osnovne šole možnost nadaljevati obvezno šolanje na višji osnovni šoli, na nižji gimnaziji, v meščanski šoli ali na realki.
