This paper reports the development and validation process of an item-bank for an adaptive computer-based test aimed at assessing kindergarten to fourth grade students' mathematical competence. A total of 528 multiple-choice items for 44 learning objectives were selected from the Quantile Framework Database, adapted and translated. A sample of 5,145 Chilean students from kindergarten to fourth grade attending 22 schools participated in the statistical validation process. Item facility and discrimination indices were analysed. Their distributions within grade levels and the four content domains were explored. Results confirm that a local validation of items was necessary.
