Recoding was not carried out.
There is a mix of levels in certificate/diploma (code 3).
Accoding to the country contact person, it would be more likely to code as medium.
In addition, it is unclear if persons who left school at age "X" do have a diploma or not.

If LIS users want to pursue a recode they may do so on their own responsability.
The mapping below may serve as suggestion.
