The simulations were applied to principals and candidates for school leadership positions. The process of creating and implementing the simulations demonstrated that it is possible to introduce a tool specifically designed to improve the decisionmaking abilities of school principals and leaders, replicating the Chilean educational context. This is a step forward in efforts to facilitate learning experiences based on decision-making situations contextualised and relevant to the training of school leaders. Finally, the use of computer-based simulations has great potential to scale the exchange of knowledge and make it universally accessible as a complement to other training opportunities in the careers of school leaders.
