Graded schools are institutions that are categorized according to the students' ages or grades. There are various synonyms for graded schools depending on the context or region, such as primary schools, elementary schools, middle schools, junior schools, and sometimes infant schools. In some countries like the UK, different terms are used for graded schools, such as infant schools for ages three to seven, primary schools for ages four to eleven, and secondary schools from age eleven to sixteen or eighteen. Regardless of the term used, graded schools serve as the foundational level of education, fostering students' social, emotional, and cognitive development and providing them with the necessary skills to succeed in their academics and future endeavors.
