ClassLens for Districts

Every teacher grades against the same rubric with the same rigor. No variation between departments.

Give teachers back the hours lost to grading so they can focus on instruction and student support.

When grades are returned promptly, families stay informed. No more 30 assignments graded the night before progress reports.

Knowledge Gap Reports give administrators and teachers visibility into class-wide understanding.

Student submissions are staged transiently in a private Google Cloud Storage bucket for AI processing, then best-effort deleted with a 24-hour bucket lifecycle policy as the failsafe. While a job runs, submission metadata and per-student results sit in an encrypted Redis job cache. It is cleared once the job finishes successfully; a job that ends incomplete keeps its cache so the work is recoverable, and either way the 48-hour expiry is the outer bound. In Grade & Review mode the drafted grades and feedback wait in a separate review queue, alongside a short-lived copy of the submission files so the teacher can read them while reviewing. Neither is tied to the job: both are deleted when the teacher releases the grades, with a 24-hour expiry as the failsafe. Once a job’s results are released or expire, ClassLens deletes the submission content, grades and AI-generated feedback it held; because the staging delete is best-effort, the 24-hour bucket lifecycle policy is what bounds a failed delete rather than the first attempt always succeeding. In the two return modes the draft grade is written to the teacher’s own Google Classroom during grading; Sheets export is the alternative path, writing grades and feedback to a teacher-owned Google Sheet instead.
