Resumen

We measure children’s over- and under-confidence in math in the first wave of the CDS (Child Development Supplement). Our analysis reveals that confident children who score above the 50th percentile on the CDS math test are only 1.3 times more likely to be overconfident compared to their peers. To ensure robustness, our model includes additional controls such as fixed effects for math and reading test score deciles, birth year, birth quarter, state, and the age at which confidence was measured. We also account for children’s general confidence and digit span scores. One might worry that controlling for general confidence absorbs too much of the variation in math over- and under-confidence; however, this approach allows us to isolate the specific effects of math-related confidence on performance.
