Recoding was not carried out.

There is a mix of levels, both in  in "other post-school qualifications" (code 3), 
                        as well as in "no post-school qualifications" (code 9).


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