<Li> The "Sonderschule für Lernbehinderte" - a special school serving children who have learning difficulties </Li> <Li> The "Schule mit dem Förderschwerpunkt Geistige Entwicklung" - a special school serving children who have very severe learning difficulties </Li> <Li> The "Förderschule Schwerpunkt emotionale und soziale Entwicklung" - a special school serving children who have special emotional needs </Li> <P> Only one in 21 German children attends such a special school . Teachers at those schools are qualified professionals who have specialized in special - needs education while at university . Special schools often have a very favourable student - teacher ratio and facilities compared with other schools . Special schools have been criticized . It is argued that special education separates and discriminates against those who are disabled or different . Some special - needs children do not attend special schools, but are mainstreamed into a Hauptschule or Gesamtschule (comprehensive school) and / or, in rare cases, into a Realschule or even a Gymnasium . </P>
