Shared rubric grading means a teacher and a substitute or co-teacher mark every paper from one written answer key and one written rubric. You agree on full credit, accepted equivalents, and partial credit before either stack is marked. Graider compares each answer with the key and the rubric uploaded for that class, and a teacher reviews the marks before anything goes back.
The standard slips when it lives only in a conversation. A wording accepted on the first stack can lose the point on the next stack. The written key and the written rubric give both of you the same starting point, and the score that goes back is the one a teacher kept or overrode at review.
A teacher who marks several sections of one course can follow that same written standard in consistent grading across class sections. This guide covers two people: a co-teacher who joins the class, and a substitute who may be marking a different class.
Graider is the AI red pen for paper grading, a product of DM Liquidity LLC. You upload the test and your answer key, photograph the stack, and Graider marks each question against that key or the rubric you provide. Each question gets one score and one comment, and a whole essay gets one score and one comment. You review, override, toggle feedback, keep the pen, and hand the work back as a PDF or an email in AI test grading.
Your key. Their papers. You review every mark. You keep the pen.
Write the answer key and the rubric once, on a page both teachers can read, before either person photographs a stack. On the key, list the full-credit response, every equivalent you accept, and the points. "Photosynthesis converts light energy into chemical energy" might be 2 points. "Light energy becomes chemical energy stored in glucose" can earn those same 2 points. Write the number on every line you accept, so a later stack uses the same point values.
Open items live on the rubric you upload with the key: an essay, a multi-step explanation, or a response with many right wordings. The rubric names what full credit includes, what a middle score includes, and the points. That writing feeds one score and one comment for the question, and one score and one comment for a whole essay. You review that score and edit that comment. How to write a rubric AI can follow walks through criteria, partial credit, and examples you can upload with the key.
Number each question the same way on the test students write on and on the key. Question 4 on the first teacher's copy is question 4 on the substitute's copy, and question 4 on the key. Keep the question order identical, so the key you wrote once still lines up with every stack.
If a question has parts, number each part when you score the parts as separate questions, so each numbered question gets one score and one comment. If you score the parts together, keep one number and list the full-credit combination and the partial-credit combination there.
Decide partial credit before the first paper is marked. Write the partial response and the points it earns. "Names the cause and leaves out the document" is 1 of 2. "Shows the method and drops the units" is 2 of 3. Both teachers use those same examples, and each partial is checked at review.
Graider does not read or score diagrams, graphs, or drawings. If a question asks for a sketch, a graph, or a labeled drawing, set those points yourself inside the one score for that question. A written label can stay on the key, inside that same score and comment.
A class in Graider has an owner. That teacher can invite a colleague with a teacher invite code. The colleague enters the code and joins as a co-teacher, on their own account. The join form says you teach the class together.
Tests on that class, including the answer key uploaded with the test, are available to every teacher on the class. A co-teacher can open the class, photograph a stack, and grade it against the test already there. Any teacher on the class can review a score, override it, and edit the comment. The class owner is the teacher who can delete the class.
The key stays on that class, and question rows stay with the teacher who created them. A co-teacher grades the test already on the class. A different class needs that same written key uploaded again.
A substitute who marks a different class, or two teachers who each own a section, each upload that same written key and that same rubric and grade their own stack. Photograph each stack on its own class, and confirm the roster match for that class.
The teacher who owns the class reviews and overrides before the work goes back. Keep a score when it matches the key or the rubric. Override it when you disagree, and name the reason in the comment: a full-credit line, a partial-credit line, or points you set from the rubric.
After a stack is marked, review before you hand back. The only flag is the Low confidence badge on an answer Graider found hard to read. Open every badge. Read the student's answer as text, compare it with the paper and your key, and override when you disagree.
Before you finish a stack, check:
Set the feedback toggle the same way on each class's test. Turn feedback on when comments should travel with the scores, and off when you will go over the test with the class. On a short answer, name the question and one next step. On an essay, the one comment covers the whole piece.
Hand each paper back as a PDF or an email after you finish review for that class. When you finish review and hand back, Graider emails the student account a "Your grade is ready" notice. Graider does not send the paper to families for you. You hand the marked paper back.

Shared rubric grading means a teacher and a substitute or co-teacher mark from one written answer key and one written rubric. Graider returns one score and one comment per question, and a whole essay gets one score and one comment. You review, override, toggle feedback, and hand work back as a PDF or an email.
Agree on the written key and rubric first. A colleague joins the class as a co-teacher with a teacher invite code, on their own account, and grades against the test already on that class. A substitute marking a different class uploads that same written key and rubric and grades their own stack.
Any teacher on the class can review a score, override it, and edit the comment. The teacher who owns the class can delete the class. When a substitute grades a class they set up, the substitute owns that class and reviews and overrides before the work goes back.
Open every Low confidence badge. It is the only flag, and it sits on a hard-to-read answer. Compare the read with the paper and your key, then override any score you disagree with. Set the points yourself on a diagram, a graph, or a drawing. When you finish review and hand back, Graider emails the student account a "Your grade is ready" notice. Graider does not send the paper to families for you.
Check every Low confidence badge, use the same written key on every stack, and toggle feedback the same way. You keep the pen.
