The assessment policy in an international school plays a key role in ensuring the objectivity, fairness, and transparency of the process for evaluating student academic achievements. It defines the criteria and standards for assessment, the methods and tools used to evaluate learning outcomes, as well as the procedures and timelines for providing feedback. The assessment policy also takes into account the individual needs and abilities of students, fostering their motivation for learning and development. Important aspects of such a policy include adhering to the principles of confidentiality, data protection, and providing equal opportunities for all students. The philosophy of assessment at Riviera International School (hereinafter RIS) is based on educational and pedagogical values. It aligns with the mission of the International Baccalaureate (hereinafter IB) program and the school, and is intended to support the achievement of the educational and ideological goals of the program, which aims to nurture internationally-minded individuals who, recognizing their common humanity and shared responsibility for the planet, contribute to the development of a better world. The assessment policy is designed to promote the development of lifelong learning skills in students, as well as all aspects of the IB learner profile. The tasks proposed for assessment purposes help develop students’ skills in knowledge acquisition, research, risk-taking, thinking, and communication, thereby contributing to the formation of a well-rounded individual.
