One of the main problems in professional technical training in the police service lies in the disconnection between the theoretical content taught in classrooms and the practical skills required in the police field. The general purpose of this research is to determine the impact of the design and implementation of spiral assessments on the development of hard skills in subjects participating in professional technical training. The research paradigm that guides the process that has been delimited from the qualitative-quantitative perspective is taken into account. In addition to that, a series of systematic, empirical and critical research processes are taken into account that lead to the use of data collection instruments of a qualitative and quantitative nature; Techniques such as documentary analysis, direct observation, evaluative rubrics and surveys are taken into account, integrating and enabling analysis, interpretation and joint discussion.  With all of the above, it is assumed that learning processes that combine hard and soft skills, and that are implemented in an iterative and reflective manner, promote comprehensive development and better adaptation to professional challenges.
