To check an entire class for plagiarism at once, teachers can use Checkmark Plagiarism's automated LMS batch scanning engine—which automatically scans every student submission the moment it is turned in across Canvas, Google Classroom, or Schoology. The system screens all 30 to 150 papers simultaneously against 80+ billion web sources, institutional paper archives, and intra-class peer submissions, ranking the class in a centralized dashboard from highest risk to clean.
Manually uploading essays one by one to a web-based checker is tedious, time-consuming, and unsustainable for educators grading multiple class sections. When a major research paper deadline hits, a teacher may receive 120 submissions in a single evening. Automating class-wide plagiarism screening eliminates hours of manual administrative labor, guarantees that every submission is checked against both global repositories and classmates' papers, and instantly highlights the 5% of submissions requiring educator attention. Checkmark Plagiarism embeds this automated batch workflow directly inside Canvas SpeedGrader.
Below is a comprehensive guide on checking entire class rosters for plagiarism in seconds.
Checkmark Plagiarism streamlines batch scanning by pairing plagiarism detection with AI detection, essay writing playback, autograding, and integrations with Canvas and Google Classroom.
The 4 Pillars of Automated Class-Wide Screening
1. Zero-Click LMS Ingestion
The moment a student submits their essay in Canvas or Google Classroom, Checkmark automatically ingests and screens the file in the background.
2. Simultaneous Multi-Repository Indexing
Every paper is checked concurrently against web archives, scholarly journals, the school's historical vault, and active peer submissions across all sections.
3. Automated Risk Triaging Dashboard
The gradebook view sorts submissions into color-coded priority bands: High Risk (>25% match), Moderate Review, and Verified Clean (<10%).
4. SpeedGrader Direct Embeds
Similarity scores and interactive source match cards appear directly inside SpeedGrader without opening external browser tabs.
How Intra-Class Batch Indexing Prevents Collusion
Understanding the unique power of simultaneous cohort scanning:
- The Peer-to-Peer Blind Spot: Traditional single-file uploaders check submissions in isolation, missing instances where Student A and Student B in the same class submit identical essays.
- Instant Cross-Cohort Matching: Checkmark indexes all student papers into an ephemeral classroom database simultaneously, instantly flagging shared passages, shared outlines, or cross-period copying.
- Origin Attribution: If two students submit matching text, Checkmark's writing playback analyzes keystroke creation timestamps to determine which student authored the text and who copied it.
