Introduction: first aids are an effective form to provide care in accidents at home, work, study and public places. In Medellin and Bello is unknown the profile of knowledge of subjects in high school and there are no valid and reliable scale to measure them. Objective: to construe and to evaluate a scale of knowledge in first aids and analyze the score in students of tenth and eleventh. Materials and methods: cross-sectional study in 445 students selected using probability sampling. In the evaluation of the scale was determined appearance, content and construct validity, reliability with Cronbach α and internal consistency with Pearson coefficient. The Knowledge profile was analyzed with frequencies and summary measures, U Mann-Whitney, Spearman correlation, ANOVA and multivariate linear regression. Results: the reliability was 0.7, significant correlations were found between each point of the scale and global knowledge score, which was 42(on a scale of 0-100) and had no statistical association with age, gender, grade or municipality of residence, only there was association with the social stratum. Conclusion: the knowledge was unsatisfactory demonstrating the need to develop and implement Education Information and Communication programs in health. The scale showed good validity, reliability and internal consistency
