 In addition to these, many of the Moroccan "marriage migrants" who arrived in the Netherlands by marrying an immigrant already living in the country as well as the 'in-between-generation' which arrived while aged 6-18 have a low education.An outcome of this circumstance is a poor command of the Dutch language among these groups.While almost half of Dutch and Iranian origin pupils attend higher secondary education (Hoger algemeen voortgezet onderwijs or "havo") or pre-university education (Voorbereidend wetenschappelijk onderwijs or "vwo"), only a fifth of Moroccan pupils did so in 2005.
