Hi David:
You've oulined your system very nicely. Thank you for sharing.
The challenge of two teachers is interesting. Interrater reliabilty (the degree to which two or more teachers will arrive at the same grade would be an interesting survey. You could compose one using a likert scale, based on a rating of 1-5. Yo might want to look into this methodolog since you are practicing it based on school policy. You might be surprised what you'd find.
Regards, Barry
