Tutor LMS Gradebook stores submissions and grades across several tables. Assignment submissions sit in wp_tutor_assignment_submissions with file attachments and grader notes, while final letter grades and weighted scores live in wp_tutor_gradebook linked to the course and the learner. The default gradebook screen shows a long list of submissions waiting for action, but it does not separate work waiting on a grader, work currently being graded, and work already returned with feedback.

SleekView Kanban reads the gradebook tables and surfaces a grading status field as a board grouping. You get one column per status value, one card per submission, and card faces that show learner name, assignment title, course, days waiting, and assigned grader. Filter by course, grader, or due date before the board renders so the lead grader only sees the slice that matters for today's queue.

Drag a submission card from Submitted to Grading and SleekView writes through Tutor LMS Gradebook's grading functions, which keeps grader assignment notifications, learner email confirmations, and gradebook score updates firing normally. Returned submissions stay visible for follow-up questions, graded submissions feed the certificate eligibility check, and the grading team finally sees their queue as a visual flow instead of a flat list of every submission ever made.

Default Tutor LMS Gradebook admin treats every submission the same once it lands in the queue. Submitted, in-progress, and graded work sit together in a long chronological list, which makes the actual workflow invisible. The team has no easy way to see how many submissions are waiting on an assigned grader today, or how many returned-for-revision submissions never came back.

A kanban changes the unit of attention from a chronological queue to a grading stage. Each card is one submission, each column is one stage in the grading lifecycle, and the eye can scan eighty cards in seconds and notice the submissions that have been Submitted for more than five days. That is the moment a lead grader catches a queue blowing past the published turnaround time.

The drag-to-update mechanic also collapses assign, grade, and return into single drag actions that fire the same Tutor LMS Gradebook hooks the default admin does.
