Characteristics of A Great Teacher
How To Grade Teachers And Schools?
The data is a representation of our school and county's test scores. Our school is slightly behind the average of other schools in the county. The plan for the future of grading teachers are to use the bell curve.

We believe teachers and schools should be graded using the bell curve/ normal distribution; however, we believe they should be ranked by mean . The tie breaker would be the lowest standard deviation.
Why The Bell Curve?
The max. and min. are extreme outliers
The mean is a good representation of the center of the data
Compare teachers using there z-scores
