Citizenship and Social Development adheres to the rationale of the senior secondary Liberal Studies curriculum. The curriculum emphasises helping senior secondary students understand the situations of Hong Kong, the country and the contemporary world, as well as their pluralistic and interdependent nature. Through the learning process, students can connect the knowledge learnt in various subjects at the junior and senior secondary levels, and understand, study and explore different topics from 5 multiple perspectives, so as to construct more knowledge relevant to various themes and build up a more solid knowledge base. Furthermore, students can understand the complexities, major considerations and priorities involved in the topics, decision-making process and different solutions to problems.
