Differential Effectiveness Report Estimates All Years Multi-Subject Estimate Table Multi-Subject Estimate Graph All Schools, Similar Intake, Same District Report Types of School Value-Added Reports

All Schools, Similar Intake & Same District Comparisons Report

Distribution of schools’ value-added estimate shown by a box-and-whisker plot School with the highest value-added The box encloses the estimates of middle 50% of schools School with the lowest value-added 75 percentile 25 percentile median

This school has value-added slightly above 75% of all schools

This school has value-added well above 75% of similar intake schools

This school has value-added above average among schools from the same district

Estimates All Years Report Enable comparison of value-added performance of a subject across the years Data in tabular form Name/Group Value-Added Stanine LowEstimateHigh Group of schools with similar value- added

Stanine A stanine is a standardized score with a mean of 5 and a standard deviation of 2. They range from 1 to 9. There are two kinds of stanines, (a) School intake: To categorize schools into groups with a similar intake, the average AAI was calculated of all students in all schools at the S5 level and the average core 3 was calculated of all students in all schools at the S7 level. (b) School value-added estimates: To categorize schools into groups with similar value-added

stanine = 7 Similar intake Group × : stanine of a school Normal distribution (Converted from average AAI )
