This paper presents a regional analysis of the effects of educational policies implemented in Spain between 1992 and 2003, focusing specifically on school failure rates. We consider the impact of expenditure per pupil, class size, and pupil-teacher ratio on dropout rates at the end of compulsory education and on the proportion of early school-leavers in the 18-24 year age group. Our results indicate that higher levels of educational expenditure per pupil and lower class sizes and pupil-teacher ratios reduce rates of dropout and early school-leaving (although class-size is not always significant). However, the magnitude of the effects of these variables is small at the average level.
