What This Calculator Does
This calculator estimates an overall diagnostic score from several entered domain scores. It is built for planning and review. It does not replace official reports. Official i-Ready results use protected rules. Schools should follow the score report supplied by their system.
Why Overall Scores Matter
An overall score gives a quick view of current performance. It helps teachers, tutors, families, and coordinators discuss support needs. It can also show growth between two testing windows. A single number should never be used alone. Domain details often show the best next step.
Domain Based Review
Each domain can receive its own score and weight. A higher weight gives that domain more influence. Equal weights create a simple average. Custom weights are useful when a program values one area more than another. The calculator also shows each contribution. This makes the final estimate easier to explain.
Placement And Growth Checks
Placement bands are user defined. This matters because grade, subject, season, and school policy can change the meaning of a score. Enter the ranges used by your report or local guide. The tool then labels the estimated result. You can also add a previous score and a goal. The growth section shows score change and remaining gap.
Careful Use
Use this page as a planning helper. Do not use it for diagnosis, grading, promotion, or clinical decisions. Scores can be affected by attention, time, device issues, language, and testing conditions. Review student work, teacher observations, and official reports together. This balanced view is safer and more useful.
Exporting Reports
CSV export is useful for spreadsheets. PDF export is useful for a quick printed summary. Keep exported files private. Student data should be handled with care. Avoid adding names when a simple identifier is enough. The calculator works best when the entered data is accurate and the placement ranges are reviewed before sharing.
Intervention Planning Notes
After the estimate appears, study the lowest weighted domains first. These areas may need targeted practice, reteaching, or enrichment. Strong domains can guide confidence building. Recheck scores after a new testing window. Trends are more helpful than one isolated score. Share findings in plain language so families understand the plan and next steps clearly.
