In terms of expenditure, in 1981, teacher salaries accounted for 40% of expenditure, and this figure rose to 50% in 1991, before declining approximately 45% in 2001. Whereas insurance wages increased gradually, starting at 2% in 1981 and reached 8% in 2001.
Expenditure on resources of books was 15% in 1981. Then this proportion increased slightly to 20% in 1991. After the following years, it dropped considerably to 9%. While others’ staff salaries decreased significantly, from 28% in 1981 to 15% in 2001. In contrast, expenditure on furniture and equipment followed an opposite trend, starting at 15% in 1981 and declining slightly to 5% in 1991 before rising again to 23% in 2001.
