Cambium Test Score Analysis 3 — Questions and Answers
Question 1: A Cambium Assessment score report shows a student's scores broken into 'reporting categories.' What is the primary purpose of these categories?
- To rank students against each other within a classroom
- To show strengths and weaknesses across specific content standards (Correct answer)
- To display how many minutes were spent on each section
- To indicate which questions the student skipped
Correct answer: To show strengths and weaknesses across specific content standards
Reporting categories disaggregate the overall score into standard-specific areas, helping educators pinpoint instructional needs.
Question 2: When comparing a student's Cambium scores year-over-year, which indicator most directly measures academic growth?
- The proficiency level label
- The Student Growth Percentile (SGP) (Correct answer)
- The total number of questions answered
- The test completion time
Correct answer: The Student Growth Percentile (SGP)
The Student Growth Percentile (SGP) compares a student's growth to that of academic peers with similar prior scores, isolating growth independent of achievement level.
Question 3: A class summary report from Cambium shows a bimodal score distribution. What does this typically suggest for instruction?
- All students have mastered the content
- The class may contain two distinct groups with different instructional needs (Correct answer)
- The test was too easy for the class
- Scores should be averaged to get one representative score
Correct answer: The class may contain two distinct groups with different instructional needs
A bimodal distribution with two score peaks suggests the class has two distinct performance groups, indicating a need for differentiated instruction.
Question 4: On a Cambium score report, a student's score falls in the 'Not Proficient' band but near the cut score. What instructional action is most appropriate?
- Retain the student automatically
- Provide intensive intervention as if the student scored in the lowest band
- Offer targeted support focused on the skills just below proficiency (Correct answer)
- Disregard the score since it is close to the cut
Correct answer: Offer targeted support focused on the skills just below proficiency
Students near the proficiency cut score need targeted, strategic support rather than full intensive intervention, as they are close to meeting standards.
Question 5: What is the primary reason Cambium Assessments use Item Response Theory (IRT) for scoring rather than simple percent-correct?
- IRT is faster to calculate
- IRT accounts for item difficulty, making scores more accurate reflections of ability (Correct answer)
- IRT eliminates the need for multiple test forms
- IRT ensures every student gets the same questions
Correct answer: IRT accounts for item difficulty, making scores more accurate reflections of ability
IRT-based scoring considers the difficulty, discrimination, and guessing parameters of each item, producing a more precise estimate of student ability.
Question 6: A Cambium score report shows a student's 'Claim' scores alongside their overall score. What do 'Claims' represent?
- Statements about what a student knows and can do within a content area (Correct answer)
- Complaints filed by students about test fairness
- The number of correct answers in each section
- Predicted future performance scores
Correct answer: Statements about what a student knows and can do within a content area
Claims are broad statements about student knowledge and skills in a content domain, derived from performance across related test items.
Question 7: Which score report feature on Cambium assessments helps educators identify whether a school's achievement gap between subgroups is narrowing over time?
- Individual student percentile ranks
- Disaggregated subgroup proficiency trends (Correct answer)
- Classroom average scaled scores
- Student growth percentiles for one year only
Correct answer: Disaggregated subgroup proficiency trends
Disaggregated subgroup proficiency trends allow comparison of performance across demographic groups over multiple years, revealing whether gaps are closing.
