What is the role of Formative Assessment in Response to Intervention (RTI)?

A formative assessment is a planned process in which assessment-elicited evidence of a student’s status is used by teachers to adjust their ongoing instructional procedures or by students to adjust their current learning tactics (Popham, 2008). To build an effective system, Tier 1 instruction may look different from school to school depending on the predominant needs of their population (e.g., LEP, FRL, Gifted). For example, one school may require intensive ESL support as a part of Tier 1 instruction to meet the 80 percent criterion and another school may require enrichment to ensure progress for high-achieving and/or gifted students as a part of Tier 1 instruction. For those schools that meet the 80 percent criterion, it is still essential to examine the effectiveness of the core and ensure growth of all students.
