How is the teacher rating calculated?

Example – Spanish 8th grade test

Step 1 – We gather all the pre and post test scores from last year. The possible scores range from 0 to 100.

Step 2 – We group the students based on the pre test scores; for example, all the students who got 30 on the pre test.

Step 3 – We take the average of these students' post scores; say 65 and this average;65 becomes the average growth target for all students who got 30 on the pre test.

Step 4 – We do the same calculation for all the possible pre test scores; 0-100 and generate the network's norm for the 8th grade Spanish test.

Step 5 – After students take the post test, we calculate the difference between the spring test and the average growth target for each student.

Step 6 – If a student hits his growth target, the difference between the spring test and the average growth target is 0 and the student is placed at the 50th percentile.

Step 7 – By using the standard deviation, each student receives a growth target percentile based on the difference between the spring test and the average growth.

Step 8 – The average of all students' growth percentile gives the teacher rating. [ 0-35=1, 36-45=2, 46-55=3, 56-65=4 and 66-100=5 ]
