1/3 Scale - SBG % Translation

I officially decided to use the 1/3 scale. I think it will better represent what the kids know and are able to do. I will be able to more accurately pinpoint their proficiency level for each standard. Here it is:

4.0 – 100% A

3.67 – 97% A

3.33 – 92% B

3.0 – 90% B

2.67 – 83% C

2.33 – 77% C

2.0 – 70% D

1.67 – 67% F

1.33 – 63% F

1.0 – 60% F

<1.0 – 50% F

I chose not to divide the 4.0 to 3.0 range evenly because it left 3 opportunities for an A and only 1 opportunity for a B. If a student gets a 3.33 that means they are proficient and low-partially proficient at advanced content. To me, that represents B work, not A work. 

Just so you know, in my district this is the grading scale we are given:

93-100 A

85-92 B

75-84 C

70-74 D

0-69 F
