 Haitian linguist, Yves Dejean, recalls warnings posted in the principal's office forbidding the use of Creole.In the 1970s, only one percent of the children who entered kindergarten stayed on track to obtain state certificate at the end of the sixth grade.Even after the literacy programs of the 1980s, 90% of the teachers ten years after the decree were still not able to fully integrate the Creole language into the education system.
