Abstract:
The findings in this paper question the reliability of the high schools’ ranking based on ENEM. Small schools’ test scores tend to: (i) be more extreme; (ii) have larger short run fluctuations; and (iii) have a greater weight of “non-persistent factors” in the decomposition of their scores’ variance. The ranking does not seem to be capable of summarizing all relevant available information in an efficient way. Finally, the probability that one school maintains, in the future, a given position in the ranking is small. In sum, the quality of the information provided by the ranking is low.
