There is no exact conversion table to align  AST grades with the IB marks a student earns from the IB Organization!

AST Grading Scale:

A = 100-93

B = 92-85

C = 84-78

D = 77-70

F = 69 or lower

The conversion chart below is used as a guide for teachers when they submit  Predicted Grades to the IB Organization. This is completed in April of the year of the  IB assessment. It's important to to note, the actual IB score a student earns in an IB course may be different than the Predicted Grade submitted. There are numerous variables teachers cannot control. AST does not share Predicted Grades with students or parents. 

7 = 100

6 = 99-98

5 = 97-96

4 = 95-91

3 = 90-83

2 = 82 – 78
