What is the difference between formative and summative assessments, and how are they used in IEP planning?

• A. Formative are end-of-year tests; summative are ongoing
• B. Formative assessments are ongoing to inform instruction; summative assessments evaluate mastery at a point in time; both inform progress toward goals and MTSS decisions
• C. Formative are standardized tests; summative are classroom quizzes
• D. Formative measure behavior; summative measure attendance

Answer: (B)

Formative vs summative assessments and how they support IEP planning. Formative assessments are ongoing checks during instruction that show how a student is progressing toward current learning targets. They give quick, actionable data that teachers use to adjust instruction, modify supports, and reteach as needed so a student stays on track toward goals. In IEP planning, this ongoing data fuels progress monitoring for annual goals and helps determine whether adjustments to services, accommodations, or instructional strategies are needed. It also feeds MTSS decisions by indicating which students need intensified supports or changes in instruction. Summative assessments, on the other hand, measure what a student has learned at a specific point in time—such as the end of a unit or grading period. They provide a snapshot of mastery and are used to determine whether goals have been met and to document progress for IEP reports and eligibility decisions. Because both types of data inform progress toward goals and MTSS decisions, formative data guide day-to-day instruction while summative data confirm mastery and influence longer-term planning.
