The local school district has a SAS data set called DISTRICT that contains the rubric used for classifying teachers’s
annual evaluations. The evaluation rating is based on two components: a teacher score and a curriculum grade. The data
set DISTRICT serves as a lookup table for determining the final evaluation rating based on a given teacher score and a
curriculum grade.
Currently, there are 10 elementary school teachers awaiting evaluation. Their information is stored in the SAS data set
named TEACHERS. To determine the evaluation ratings for these teachers, please follow the steps below.
