Unemployment rates in Denmark in 2011 were below the OECD average. Teachers are trusted professionals with fewer teaching hours than the OECD average and good salary conditions, but they receive less feedback and fewer professional development opportunities than the OECD average. At primary and lower secondary levels, teachers follow a pre-service teacher training programme of four years including a teaching practicum, at upper secondary level, it is a six-year training programme, also including a teaching practicum.
