This study presents the development process and initial validation of the NyTid test, a process-oriented movement assessment tool for compulsory school pupils. A sample of 1,260 (627 girls and 633 boys; mean age of 14.39) Swedish school children participated in the study. In the first step, exploratory factor analyses (EFAs) were performed in Sample 1, consisting of one third of the participants. The EFA indicated that the 17 skills in the test could be reduced to 12 and divided into four factors. In the second step, the suggested factor structure was cross-validated with confirmatory factor analyses (CFAs) in the larger Sample 2. The NyTid test adopts a holistic perspective in which qualitative criteria offer an alternative approach to product-oriented measurement. The study confirms that the NyTid test is a valid process-oriented assessment tool designed for typically developed children aged 12 and 16.
