| Abstract | I consider two tests of receptive vocabulary administered, respectively, in the first and third wave of starting cohort 3 of the National Educational Panel Study (NEPS). The first test was administered in 2011 in a sample of children visiting a Kindergarten in that year; a second test took place two years later. I compare test results of 518 children who have participated in both tests. I first use 38 items which are identical in both tests. Based on sum scores, one sees a remarkable increase in the receptive vocabulary. I then show that the data are not compatible with a joint Rasch model which assumes time-invariant item parameters. As an alternative basis for longitudinal comparisons I suggest that a sufficient condition for two tests measuring the same kind of competence is that they consist of identical items. (Orig. ). |
