General Directions for Identifying Disproportionality:
For disproportionality calculations, you should look at the LEA's average percentages for mathematics, reading/ELA, and science (page 1 of the PDF sent to you), and then look at the disaggregated data (starting on page 2 of the PDF) to see if there are any entries that are significantly above the LEA's average percentages. If you find some percentages for a focal group that are significantly above the LEA's average percentages, you should check 3–10 specific tests for that focal group using the calculation tool.

If you find trends of disproportionality (over the 2.0 risk ratio threshold), then you should select “Yes” for question 10 and mark that focal group for question 11 on the Justification and Assurances form.

If you do not find trends of disproportionality (less than 2.0), then you should review other percentages for focal groups that are significantly above the LEA's average percentages. If no trends of disproportionality are found in any of the focal groups, you should select “No” for question 10 and mark "N/A" for questions 11 and 12.

You are not required to review every focal group for every test. If you have extremely low numbers of students (less than five) that result in high percentages, you can skip that entry in the disproportionality calculation. This may be the case for some very small districts (less than 1,300 students) for all focal groups. If that is the case, you should select “No” for question 10 and mark "N/A" for questions 11 and 12.

Specific Directions for Using the Calculation Tool:
You only need to enter information in the green cells. Follow steps 1–5 below and data in the white and orange cells will populate automatically.
3
Step 1—For cells B9 and B10, select a Focal Group and Focal Assessment from the dropdown menus.
4
Step 2—In cell B12, use your district's participation data from the PDF sent to you to enter the number of Alternate 2 Tests indicated for the focal group and focal assessment you selected in Step 1.
5
Step 3—In cell B14, use your district's participation data from the PDF sent to you to enter the number of Alternate 2 Tests indicated for all students in your LEA who took the focal assessment.
6
Step 4—In cell D12, use the Statewide Data tab below to enter the number indicated for the focal group and focal assessment you selected in Step 1.
7
Step 5—If either of the calculated risk ratios in the table are above 2.0, then select "Yes" for question 10 on the Justification and Assurances Form, and mark the focal group for question 11.
(In the sample below, since Risk Ratio #2 is above 2.0, you would select "Yes" for question 10 and mark "African American" for question 11.)
