Grade 9 MathematicsAbout the Practice Test Scoring GuidesThe Smarter Balanced Mathematics Practice Test Scoring Guides provide details about the items,student response types, correct responses, and related scoring considerations for the SmarterBalanced Practice Test items. The items selected for the Practice Test are designed to reflect a broad coverage of claims and targets that closely mirror the summative blueprint. a range of student response types. a breadth of difficulty levels across the items, ranging from easier to more difficult items.It is important to note that all student response types are not fully represented on every practice test,but a distribution can be observed across all the practice tests. The items presented are reflective ofrefinements and adjustments to language based on pilot test results and expert recommendationsfrom both content and accessibility perspectives.Within this guide, each item is presented with the following information1: Claim: statement derived from evidence about college and career readiness Domain: a broad content area that contains related targets and standards (i.e., Geometry) Target: statement that bridges the content standards and the assessment evidence thatsupports the claim Depth of Knowledge (DOK): measure of complexity considering the student’s cognitiveprocess in response to an item. There are four DOK levels, a 4 being the highest level. Common Core State Standards for Mathematical Content (CCSS-MC) Common Core State Standards for Mathematical Practice (CCSS-MP) Static presentation of the item: static presentation of item from test administration system Static presentation of student response field(s): static presentation of response field fromtest administration system Answer key or exemplar: expected student response or example response from score pointvalue Rubric and applicable score points for each item: score point representations for studentresponsesThe following items are representative of the kinds of items that students can expect to experiencewhen taking the Computer Adaptive Test (CAT) portion of the summative assessment for high school.A separate document is available that provides a high school sample performance task and scoringguide.1Most of these terms (Claim, Domain, Target, DOK, etc.) are further defined in various other Smarter Balanceddocuments, as well as the Common Core State Standards for Mathematics. Refer to the Content Specificationsfor the Summative Assessment of the Common Core State Standards for Mathematics for more information.Smarter Balanced High School Mathematics Practice Test Scoring Guide2
