This research is entitled Influence of the Scratch Program in Computational Thinking in Primary School Students of the National Police of Peru Alférez Mariano Santos Mateos, Tacna 2018, leading to the degree of teacher in University Teaching and Educational Management. The objective of the research is to determine the influence of the Scratch program on the computational thinking of the students of the I.E. PNP Alf Mariano Santos Mateos from the city of Tacna, 2018. To do this, a methodology of a basic type is established, with a quantitative, correlational-explanatory approach, with a non-experimental design. The research concludes that the Scratch program significantly influences the computational thinking of the students of the I.E. PNP Alf Mariano Santos Mateos from the city of Tacna, 2018, from the P-value calculated from 0.00 which, being less than 0.05, shows the significant relationship, and a value of R-square which is an indicator that 86.59% of student cases, Regarding the computational thinking achieved, they have been influenced by the use of the scratch program, demonstrating in this way the relevance of the program as a source to improve the competences of students in the field of computing, given the insertion of technologies and information systems for the facilitation of communications and decision making.
