The main objective of this work was to validate and compare the level of Declarative Tactical Knowlwdge (DTK) of soccer players of different categories and positions. 221 male soccer players were part of this work. Taking the results into account we can take into consideration the following aspects: from the comparison of the DTK per category, the differences shown by the sub-14 category, for the sub-15 category (p=0,001) and category sub-14 (p=0,003), however significant differences between the sub-15 category (p=0,001) and the sub-17 category were not found. When soccer players got into groups for specific positions, significant differences of DTK were not found between them, even though there was an advantage by the descriptive scores for middle-field players and forward players. Therefore, it can be concluded that about 14 years, the CTD is a factor that differentiates the athletes in each category, but after 15 years, this knowledge is probably already assimilated procedurally by the player when it undergoes a systematized training and constant practice over the years.
