Rubrics
My understanding is that rubrics can be used with letter grades, percentages or number scales. Our rubrics and report cards uses a 5 point scale as such:
5 - Excellent achievement of grade level learner expectations-
(Understands and applies new concepts in a wide variety of learning situations. Consistently uses required skills and strategies effectively.)
4 - Very Good achievement of grade level learner expectations-
(understands and applies new concepts to most learning situations. Frequently uses required skills and strategies effectively.)
3- Satisfactory achievement of grade level learner expectations-
(Understands and applies concepts to specific learning situations. Uses most required skills and strategies appropriately.)
2- Improvement needed in meeting grade level learner expectations-
(Requires repeated instruction to understand and apply new concepts in learning situations. Needs much support to use required skills and strategies.)
1- Not yet meeting level learning expectations -
(Unable to understand and/or apply new concepts in learning situations. Has great difficulty using skills and stategies.)
When I mark anything, I use this as a guide and give each student a mark from 1 to 5. The mark of 3 is acceptable but most of our parents like to see a 4 or 5 on the work.
When marking effort, organization, prepared for class, positive attitude, neatness, following classroom routines, respect for others, respect for property, etc, we use the same scale:
5=consistently
4=frequently
3=most of the time(occasional reminder)
2=requires adult assistance (frequent reminders)
1=not yet (this is reserved for very severe cases!)
The rubrics are helpful but you must first decide on the criteria that goes with each score. What one person thinks "organizes material for learning" means could be totally different from what another thinks. Our staff (k-6) took a look at the report card descriptors and brainstormed what criteria went with each descriptor. This helped a lot. I base my academic rubric criteria on the curriculum statements (benchmarks).
Something else that works well is to ask the children what they would give themselves, based on the rubric, compared to what you would give them. They can often tell you what they could have improved on to raise a mark of a 3 to a 4 or 5.
