Download free printable answer sheetsGrade tests from PDF
Place the completed answer key first, followed by all student answer sheets, and scan the stack into a single PDF. Choose that file in the grader to read the bubbles, score each student against the key, and create a marked PDF. The grader reads our printable answer sheets, and can’t read test pages or other brands’ answer forms.
The scanned PDF is processed entirely on your device and is never uploaded or stored. Premium history keeps only the results from your latest 50 scans, not scanned PDFs or page images. It does not read or store student names or other personally identifying details from the sheets. The PDF filename is saved as the history label, so avoid names or identifying details in filenames.
Grade your scanned PDFBatch bubble sheet grading
Keep a class set together in one PDF rather than selecting each student sheet separately. The answer key on page 1 is used to grade the student sheets that follow just like using a Scantron machine. Blank pages are skipped, and unrecognized or mismatched sheets are listed as not graded rather than silently assigned a score.
Scan in grayscale at 300 DPI and print sheets at 100% / Actual Size. Corner markers let the grader read rotated pages; fill bubbles completely with dark pencil.
