This dataset contains quantitative student data acquired during the administration of two validated Computational Thinking (CT) assessments for upper primary school (grades 3 and 4): the Beginners' CT test (BCTt) [1] and the comptent CT test (cCTt) [2] To compare the psychometric properties of both instruments a comparative analysis was conducted with data acquired in schools in Portugal from the same school districts. More specifically, we analyse the results of: - the BCTt test administered in March 2020 to 374 students in grades 3-4, - the cCTt test administered in April 2021 to 201 different students in grades 3-4. These students had no prior experience in Computational Thinking, as this was not part of the national curriculum at the times of administration. The detailed psychometric comparison is published in Frontiers in Psychology - Educational Psychology [3] and provides indications regarding the use of both instruments for grades 3-4. A README is included and provides additional information regarding : - the requirements for re-use. - the specific content of the 2 csv files The BCTt is available upon request to maria.zapata@urjc.es and the cCTt items are available in [2] with an editable version being available upon request to laila.elhamamsy@epfl.ch.
