The research discusses whether Arab legislations agreed on a one unified term to describe that stage of human life and what is the effect of eligibility for performance. It highlights the importance of the intervention of humanities in this field, due to the need of integrated sciences to get well-established treatment based on scientific facts that will be implemented on juveniles to avoid mistakes. I ask Allah to grant success and the completion of this research in the future, so that we may expand the concept of criminal responsibility and its connection to the juvenile, and the consequent provisions or measures and penalties that may be required to stop juveniles from committing crimes, as well as the importance of knowing the reasons behind juvenile delinquency and Inclination.
