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.
