This paper presents a pilot study on the evaluation of instruments for data gathering for an epistemic game development competition for high school students. The initial results show that a significant percentage of the students who participated in the competition appear to exhibit a skillset of professional attitude, software-related knowledge, and employability traits, and this skillset may be attributed to the intervention. The data was validated through a two-method triangulation technique that utilized expert evaluation and participant interviews. The data analysis shows early indicators of the desired learning outcomes, although a more thorough methodology is needed to verify this. Furthermore, the competition acts as an awareness campaign that promotes computer science studies through a gamification process. It is proposed that competitions of this type are held and evaluated on an annual basis to maximize the benefits and to further prepare students to acquire early in their studies a skillset that will make them the innovators of the future society.
