i-Ready Diagnostic is a computer-adaptive assessment that measures students’ academic progress in reading and mathematics. It is aligned with the Common Core State Standards (CCSS) and provides individualized learning recommendations based on student performance.

Benefits of i-Ready Diagnostic
- Determines individual areas of need: i-Ready Diagnostic identifies specific areas where students need additional support.
- Provides personalized learning plans: Based on diagnostic results, teachers can tailor instruction to address individual student needs.
- Tracks student progress over time: i-Ready Diagnostic allows teachers to monitor student growth and evaluate the effectiveness of instructional interventions.
- Provides actionable data for parents: Parents can access their child’s i-Ready diagnostic scores and learning recommendations to support home-school collaboration.
i-Ready Diagnostic Scores by Grade
The following tables provide i-Ready diagnostic scores by grade for reading and mathematics. The scores are reported on a scale of 0 to 600, with higher scores indicating greater proficiency.
Grade | Reading Score Range | Mathematics Score Range |
---|---|---|
K | 200-300 | 200-300 |
1 | 250-350 | 250-350 |
2 | 300-400 | 300-400 |
3 | 350-450 | 350-450 |
4 | 400-500 | 400-500 |
5 | 450-550 | 450-550 |
6 | 500-600 | 500-600 |
7 | 550-650 | 550-650 |
8 | 600-700 | 600-700 |
Interpreting i-Ready Diagnostic Scores
Reading:
- Below 300: Students need significant support in reading fluency, comprehension, and vocabulary.
- 300-400: Students are approaching grade-level expectations but may need additional support in specific areas.
- Above 400: Students are meeting or exceeding grade-level expectations in reading.
Mathematics:
- Below 300: Students need significant support in number sense, operations, and problem-solving.
- 300-400: Students are approaching grade-level expectations but may need additional support in specific areas.
- Above 400: Students are meeting or exceeding grade-level expectations in mathematics.
Tips for Improving i-Ready Diagnostic Scores
- Regular practice: Students should engage in regular reading and mathematics practice to improve their skills.
- Targeted instruction: Teachers should provide targeted instruction based on students’ individual diagnostic results.
- Personalized learning: Students should receive personalized learning experiences that address their specific needs.
- Home-school collaboration: Parents and teachers should work together to support student learning and monitor progress.
- Data-driven decision-making: Educators should use diagnostic data to inform instructional decisions and make data-driven changes to improve student outcomes.
Conclusion
i-Ready Diagnostic is a valuable tool for assessing student academic progress and providing individualized learning recommendations. By understanding the i-Ready diagnostic scores by grade and implementing effective instructional interventions, educators can support student success in reading and mathematics.
