To determine a school's funding for the school year, OIEP uses the following seven-step process:

(a) Step 1. Multiply the appropriate base academic and/or residential weight from §39.103 by the number of students in each grade level category.

(b) Step 2. Multiply the number of students eligible for supplemental program funding under §39.107 by the weights for the program.

(c) Step 3. Calculate the school-based supplemental weights under §639.107.

(d) Step 4. Add together the sums obtained in steps 1 through 3 to obtain each school's total WSU.

(e) Step 5. Add together the total WSUs for all Bureau-funded schools.

(f) Step 6. Calculate the value of a WSU by dividing the current school year's funds by the average total WSUs as calculated under step 5 for the previous 3 years.

(g) Step 7. Multiply each school's WSU total by the base value of one WSU to determine funding for that school.
