CBE is going to roll out a new 4-point grading system for K-9 students in the upcoming academic year, similiar to the CSSD’s.
The new numerical scores represent 4 levels of achievements
4 (Excellent) – The student has demonstrated excellent achievement of grade level expectations
3 (Good) – The student has demonstrated good achievement of grade level expectations
2 (Basic) – The student has demonstrated basic achievement of grade level expectations
1 (Not Meeting) – The student is not meeting grade level expectations

The numerical system, which is discrete by default, is adequate for K-6 students. Junior high students, in my opinion, is better off with a percentage based ‘continous’ scaling system.
