Cambium Test Interim and Benchmark Assessments vs. Summative Assessments — Questions and Answers
Question 1: What is the key distinguishing purpose of a Cambium-delivered interim assessment compared to a summative assessment?
- Interim assessments are used during the school year to inform instructional decisions, while summative assessments measure year-end proficiency for accountability purposes (Correct answer)
- Interim assessments are mandatory for all students, while summative assessments are optional
- Interim assessments replace summative assessments when a student has an IEP
- Interim assessments are scored by classroom teachers, while summative assessments are machine-scored
Correct answer: Interim assessments are used during the school year to inform instructional decisions, while summative assessments measure year-end proficiency for accountability purposes
Interim assessments (such as Smarter Balanced Interim Comprehensive Assessments and Interim Assessment Blocks) are formative-in-nature tools administered at teacher or school discretion during the year to gauge learning progress. Summative assessments are administered at the end of the year for state accountability and proficiency reporting.
Question 2: Which of the following best describes an Interim Assessment Block (IAB) in the Smarter Balanced system delivered via Cambium?
- A short, targeted interim assessment focused on a specific cluster of standards, used to gauge mastery of a focused instructional unit (Correct answer)
- A full-length practice version of the summative assessment administered at the start of the school year
- A mandatory quarterly benchmark that contributes to a student's year-end proficiency score
- A scripted diagnostic interview conducted one-on-one between teacher and student
Correct answer: A short, targeted interim assessment focused on a specific cluster of standards, used to gauge mastery of a focused instructional unit
IABs are brief, standards-targeted assessments within the Smarter Balanced interim system. Unlike the full Interim Comprehensive Assessment (ICA), an IAB targets a narrow claim or set of standards — making it useful for checking understanding after a specific instructional unit.
Question 3: How do interim assessment scores on the Cambium platform differ from summative scores in terms of accountability use?
- Interim scores are for instructional use only and are not included in state or federal accountability calculations (Correct answer)
- Interim scores count for 25% of a student's official proficiency level determination
- Interim scores replace summative scores if a student scores higher on the interim test
- Interim and summative scores are averaged together to produce a final accountability score
Correct answer: Interim scores are for instructional use only and are not included in state or federal accountability calculations
Interim assessments are explicitly non-summative: their results are shared with educators and schools for instructional planning but do not factor into state proficiency determinations or federal accountability metrics (such as those under ESSA).
Question 4: A teacher wants to administer a Cambium interim assessment only to students who struggled on a recent classroom quiz. Which feature of the interim system allows this targeted approach?
- Teachers can select specific students from their roster to include in an interim testing session, rather than testing the entire class (Correct answer)
- Interim assessments automatically identify struggling students and push a test to those students' devices
- Teachers must administer interim assessments to the full class and filter results afterward
- Interim assessments are only available at the district level and cannot be limited to individual students
Correct answer: Teachers can select specific students from their roster to include in an interim testing session, rather than testing the entire class
Unlike mandatory summative assessments, interim assessments on the Cambium platform give educators flexibility — teachers or test coordinators can create sessions that include only selected students, enabling targeted use with specific groups rather than requiring whole-class administration.
Question 5: Results from Cambium-delivered interim assessments are best used for which of the following purposes?
- Adjusting upcoming lesson plans and identifying students who need additional support on specific standards (Correct answer)
- Ranking schools within a district for resource allocation decisions
- Certifying student promotion or retention decisions at the end of the year
- Replacing the summative assessment score for students who were absent on the testing date
Correct answer: Adjusting upcoming lesson plans and identifying students who need additional support on specific standards
Interim assessments are formative tools — their value lies in the timely, actionable data they provide to teachers and instructional coaches. Using them for high-stakes decisions like promotion or school ranking goes against their intended purpose and design.
Question 6: Which of the following is true about the adaptive nature of Cambium's summative assessments versus its interim assessments?
- Summative assessments are computer adaptive, adjusting item difficulty based on student responses, while many interim assessments are fixed-form (Correct answer)
- Both summative and interim assessments use identical computer adaptive algorithms
- Interim assessments are fully adaptive, while summative assessments use a fixed set of items for all students
- Neither assessment type uses adaptive delivery; all items are pre-assigned to each student
Correct answer: Summative assessments are computer adaptive, adjusting item difficulty based on student responses, while many interim assessments are fixed-form
Smarter Balanced summative assessments use a Computer Adaptive Testing (CAT) engine that selects items dynamically based on student performance. Most Smarter Balanced interim assessments, by contrast, are fixed-form — all students receive the same items — which allows teachers to analyze class-wide responses to specific items.
