| Abstract | In the National Educational Panel Study (NEPS), spelling competence is a stagespecific measure for secondary school (Stage 4). This is a challenging task because the current state of research does not offer a theory-based and empirically proven instrument that would allow for longitudinal measurement. In this paper, we present results from NEPS pilot studies in order to illustrate our work. For our research, we used an anchor-item design and IRT-based methods to verify the suitability of the test for the longitudinal survey of spelling competence. We demonstrate the reliability of the tests with regard to dimensionality and discrimination. The person parameter and the item parameter provide an insight into the item difficulty and the students’ abilities, thereby guaranteeing that the tests account for individual demands throughout secondary school. Moreover, deviance and the correlational structure of the data are taken into consideration. In summary, the selected test design and the choice of anchor items ensure that an adequate test is administered to each student. We removed about 15 – 30 % of the items in each grade to obtain a fit model. As the results for Grades 5 to 7 are nearly identical, it can be assumed that the test is reliable. The assumed five-dimensional model proves to be most adequate to measure the subskills for all grades because the deviance is lower. (Orig.). |
