i-Ready Diagnostic Interpreting Diagnostic Reports Questions and Answers 1 — Questions and Answers
Question 1: A teacher reviews a student's Diagnostic report and sees an overall Mathematics placement of "Early Grade 5." However, the domain-level report shows the student placed at "Mid Grade 5" in "Number and Operations" but "Late Grade 3" in "Geometry." What is the most appropriate instructional next step based on this data?
- Recommend the student be moved to a Grade 4 math class due to the low Geometry score.
- Assign the student Grade 5 level practice across all domains to match their overall placement.
- Use the domain-level data to differentiate instruction, providing on-level support in Number and Operations and targeted, foundational instruction in Geometry. (Correct answer)
- Focus exclusively on Grade 5 geometry concepts to try and close the gap as quickly as possible.
Correct answer: Use the domain-level data to differentiate instruction, providing on-level support in Number and Operations and targeted, foundational instruction in Geometry.
The most effective instructional practice is to use the specific data from the domain-level reports to differentiate. This student shows grade-level proficiency in one area and needs foundational support in another. A one-size-fits-all approach based on the overall score would fail to address the student's specific areas of need and strength.
Question 2: Which component of the i-Ready Diagnostic report provides a single, continuous score from K-12 that is used to measure academic growth from one diagnostic to the next?
- The National Norm Percentile
- The Grade-Level Placement (e.g., "Mid Grade 4")
- The Developmental Analysis
- The Scale Score (Correct answer)
Correct answer: The Scale Score
The Scale Score is a continuous score on a vertical scale (from 100 to 800) that measures student achievement and growth over time, from kindergarten through high school. Grade-level placement is a categorical interpretation of the scale score, the national percentile is a comparison to peers, and the developmental analysis provides qualitative instructional guidance.
Question 3: A teacher is reviewing the Diagnostic Growth report for their class. Which of the following is the most accurate interpretation of the "Typical Growth" and "Stretch Growth" measures?
- All students are expected to meet "Stretch Growth" to be considered on grade level.
- "Typical Growth" represents the average growth for a student's academic peers, while "Stretch Growth" is a more ambitious but attainable goal to help students reach proficiency. (Correct answer)
- "Typical Growth" is the minimum progress required by the district, while "Stretch Growth" is an optional, advanced goal.
- "Typical Growth" is for students on grade level, while "Stretch Growth" is only for students below grade level.
Correct answer: "Typical Growth" represents the average growth for a student's academic peers, while "Stretch Growth" is a more ambitious but attainable goal to help students reach proficiency.
Typical Growth is a normative measure showing the average annual growth for peers at a similar starting placement. Stretch Growth is a more ambitious, criterion-based goal designed to put students on a path to proficiency (if they are below grade level) or advanced achievement (if they are on grade level).
Question 4: Mr. Davis notices that a student's Quantile® measure in mathematics has increased significantly since the last diagnostic. What is the primary instructional implication of this specific data point?
- The student is likely ready for more complex mathematical concepts and can be matched with appropriately challenging materials. (Correct answer)
- The student has mastered all math standards for their current grade and should be accelerated to the next grade's curriculum.
- The student should be reassigned the same online lesson path to ensure retention of learned skills.
- The student no longer needs to participate in small group math instruction.
Correct answer: The student is likely ready for more complex mathematical concepts and can be matched with appropriately challenging materials.
A Quantile measure describes a student's readiness for mathematics instruction. A significant increase indicates that the student has grown in their mathematical ability and is ready to tackle more complex skills and concepts. This data helps teachers match students with appropriate instructional materials to continue their growth.
Question 5: When forming small instructional groups based on i-Ready Diagnostic data, which of the following reports is MOST useful for a teacher?
- The school-wide summary report showing the percentage of students in each placement level.
- The individual student growth report showing progress toward Typical and Stretch Growth.
- The class-level report that groups students by specific shared skill needs within each domain. (Correct answer)
- The report showing only the Lexile and Quantile measures for each student in the class.
Correct answer: The class-level report that groups students by specific shared skill needs within each domain.
Reports that group students by specific instructional needs are explicitly designed to help teachers form effective small groups for targeted support. While other reports are useful for different purposes, the instructional grouping report provides the most actionable data for planning differentiated small group lessons based on shared skill gaps.
Question 6: A student's report indicates a National Norm Percentile of 65. What does this number signify?
- The student answered 65% of the questions on the diagnostic correctly.
- The student scored as well as or better than 65% of a nationally representative sample of students in the same grade who took the test at the same time of year. (Correct answer)
- The student is 65% of the way toward meeting their end-of-year growth goal.
- The student is working on content that is typically taught 65% of the way through the school year.
Correct answer: The student scored as well as or better than 65% of a nationally representative sample of students in the same grade who took the test at the same time of year.
The National Norm Percentile is a comparative statistic that shows how a student's score compares to their peers nationwide. A percentile of 65 means the student's performance was equal to or better than 65 percent of the students in the national norming group. It is not a percentage of correct answers.
