District 52 has implemented the Next Generation Science Standards (NGSS) in Grades 1-8. In Grades 1-5 we are using Mystery Science curriculum. In Grades 6-8 we are using STEMscopes curriculum. Students in Grades 5 and 8 take the IL Science Assessment (ISA) in the Spring each year. This replaces the former ISAT Science Test in Grades 4 and 7.
