What this certification covers

OCR Correction sits in the Data Annotation & Labeling track (Beginner). You read 3 written modules in order — each one has to be completed before the next opens — then sit a ten-question exam marked on our servers against a fixed answer key. Pass at 80% and the certificate is issued.

Concepts tested

  • Character fidelity

    The correction matches the glyphs on the page, not what reads better.

  • Layout preservation

    Keeping line, column and reading order intact through the edit.

  • Inferred characters

    Text you reconstructed from context and marked as uncertain.

  • Language variant

    Script and regional forms that must not be swapped for a familiar one.

  • Silent normalisation

    Quietly standardising spelling or digits, which destroys the record.
