BELS-(Essential Standards): These standards are the main curricular focus of the grade. Tier 1 instructional time is spent on these standards to ensure all students are proficient on these standards. Common Formative and Summative assessments are administered to determine which students need interventions or enrichments. 

Important Standards: These standards support or extend the BELS. Tier 1 instruction time is spent to ensure understanding. Student learning is assessed; but will not be a focus of intervention. 

Nice to Know Standards: These standards are introduced and integrated during the grade as part of Tier 1 instruction.
