The development of aquatic motor skills in classes of physical education from early school age students, requires the planning of academic proposals in accordance with the requirements of motor development and biological maturation of the children during this school phase, is for this reason that the study sought to determine the effect of a physical education program on the aquatic basic motor skills in a group of 24 students aged between four and five years divided into two groups belonging to the Group 12 control and 12 to the pilot of the stars educational institution of the city of Tuluá for 14 weeks, 12 of which intervention and two for the processes of evaluation, before and after the direct intervention. There are many factors that hinder the development of aquatic motor skills in physical education classes, between them and the most important is the lack of own for their development and the low implementation scenarios, another aspect is the lack of programs designed according to driving maturity according to their age that allow a proper development of the same. These factors limit the development of motor skills, especially those with high favorability to be developed in this school year. The data analysis was used the statistical package SPSS (17.0); using descriptive statistics (mean and standard deviation), analysis of contingency tables with hypothesis Chi square test. Among the most important results of this study, the improvement of the levels can be seen in factors of familiarization and the immersion factor; When applying the final test of familiarization pilot group factor gained a result of levels of 3.83 DT 0,389, much better than the one obtained by the group control of 2.25 0,452 DT, these results belong to the level of almost always, and sometimes respectively. Similarly, the levels of the immersion factor, reflected a big improvement for the experimental group yielding results with a level of 3.42 DT 0,515 belonging to level almost always to a result for the control group of 1.25 0,452 DT which belongs to the level of never; the results confirm the effectiveness of the program of physical education on aquatic basic motor skills on the mobility of students in preschool-age children of the stars educational institution of the city of Tuluá.
