The institutions of the former educational systems are included in the groups of the present school types and numbers of grades in the following way: — the lst-8th grades of the elementary (public elementary) school in the lst-8th grades of the generál school, — the lst-Ath grades of the higher elementary school in the 5th-8th grades of the generál school, — the lst-3rd grades of the secondary school of eight grades in the 5th-7th grades of the generál school, — the 4th-7th grades of the secondary school of eight grades and the 8th grade without a secondary school leaving examination, respectively, in the 8th grade of the generál school.
