DnA is a K–12 standards-based assessment creation and administration platform providing instant scoring, formative feedback, and interactive reporting. Districts can use DnA’s high-quality, standards-based assessment content to build assessments tightly aligned to their scope and sequence—or choose to customize DnA’s prebuilt assessments—for information-rich data on student learning. Prebuilt reports give instant visibility into standards mastery, and custom reporting offers a holistic view of performance across assessments. DnA also offers built-in distractor rationales to guide in-the-moment feedback, content authoring, and live proctoring, forming a complete solution to accelerate standards mastery.
