DeSSA mathematics is Delaware's administration of the actual Smarter Balanced summative assessment (Delaware is a Smarter Balanced member state): per the Delaware DOE, the test provider for grades 3-8 is the Smarter Balanced consortium, administered each spring via the DeSSA portal. The math test is organized into four claims with published assessment targets (Smarter Balanced Mathematics Content Specifications). Claim 1 (Concepts and Procedures) publishes per-grade assessment targets, each a verbatim CCSS-M cluster heading (e.g. grade 3 Target A is cluster 3.OA.A); Claims 2-4 are cross-cutting process claims whose targets are constant across grades and draw on the same grade-level content. On score reports, Claims 2 and 4 are combined into a single reporting category, so three claim scores accompany the overall math score. Delaware administers the Smarter Balanced math summative in grades 3-8 only; the high-school accountability test is the School Day SAT (grade 11, since 2011), which sits outside the Smarter Balanced blueprint and is covered by the separate SAT coverage map, so this file carries no High School band. (DeSSA stands for Delaware System of Student Assessments, per the DOE's official DeSSA calendar.)

How the DeSSA structures Grade 3 math
Content Specifications (Reporting Categories section): the total mathematics score is a weighted composite of the four claims — Claim 1 (Concepts and Procedures) contributes roughly 50%, Claim 3 (Communicating Reasoning) roughly 25%, and combined Claims 2 and 4 (Problem Solving / Modeling and Data Analysis) about 25%. The summative blueprint (as of 2018-19) publishes item counts per test event rather than percentages: Claim 1 is 17-20 items in grades 3-5 and 16-20 in grades 6-8; the Claim 2/4 and Claim 3 reporting categories are 8-10 items each, totaling 18-20 across the two.
