If you’ve spent any time working in a California independent study charter school, you already know the headache. Every student work sample needs to be stamped with a standardized set of metadata — teacher name, student name, subject, learning period, assignment date, grade — all laid out in a precise 3×2 grid, as required by California Education Code §51747. And for most schools, that means teachers doing it by hand. Every. Single. Day.
Handwriting is messy and inconsistent. Rubber stamps can’t handle digital PDFs. Using Photoshop or Acrobat is time-consuming and requires technical know-how most teachers simply don’t have time to develop. The result? Auditors receive a patchwork of inconsistently formatted work samples, and teachers burn through precious instructional time on administrative busywork.
There’s a better way.
Introducing Work Sample Stamper
Work Sample Stamper is a web-based tool built specifically for California independent study charter schools. It automates the metadata stamping process entirely — no app to download, no training required, no per-user licensing costs. It works on any phone, tablet, or laptop.
How It Works
The process couldn’t be simpler:
- Open the form and fill in the fields — teacher name, student name, subject/level, learning period, assignment date, and grade.
- Upload your document — PDF, JPG, JPEG, or PNG files are all accepted.
- The tool stamps the document automatically with a properly formatted metadata block.
- Download your stamped PDF — ready for the student file and any future audit.
That’s it. Four steps, no headaches.
Built with Security and Privacy in Mind
Schools handle sensitive student data, and Work Sample Stamper was designed with that in mind from the ground up. Access is available to approved organizations only — teachers simply enter their work email to receive a secure access link, no password to manage. All file transfers are encrypted via HTTPS/TLS, the same standard used by banks. The tool runs on AWS infrastructure trusted by the U.S. government, healthcare organizations, and Fortune 500 companies.
Most importantly: uploaded files are automatically deleted within 5 minutes of processing. The system is fully automated, meaning no human ever views your files. Student data stays private.
Less Time Stamping. More Time Teaching.
The goal of Work Sample Stamper is simple — give teachers back their time. Compliance doesn’t have to mean manual labor. With a standardized, consistent stamp applied to every work sample, schools can walk into any audit with confidence, knowing their documentation is clean, legible, and uniform.
