  8. cDummy variables. Reference categories for school dummies are: non-vocational technical school; school located in a town with more than 3000 and less than 100,000 inhabitants; the national authorities do not have a considerable responsibility for determining the content of the courses or establishing student disciplinary policies or distributing the school budget or establishing the students assessment policies; the school principal does not have a considerable responsibility for distributing the school budget
