1. What is actually sensitive in an educational institution
| Where | Data | Why it matters | Method |
|---|---|---|---|
| Exam server and evaluation systems | Question papers, answer keys, marks, internal committee records | A serious institutional and legal exposure, especially in the window between exams and results | Degauss + crush, with a register and a named custodian |
| Student and staff records | Admission records, marksheets, personal data, fee records, staff files | Personal data under the DPDP Act | Degauss + crush |
| CCTV and access control recorders | Footage of identifiable individuals, visitor and staff movement logs | Personal data; frequently on a DVR/NVR drive nobody has considered | Degauss before the device is replaced or scrapped |
| Library management systems | Borrowing history, patron records, photographs of members | Personal data, retained for years | Degauss + crush |
| Computer labs and staff laptops | Email, saved credentials, documents, browser data | Second-owner exposure on resale or buy-back | Degauss before reassignment or release |
| ID card system drives and printers | Student and staff identity data, photographs | Bulk personal data | Degauss + crush |
| Exam and placement cell files | Personal data of students, often shared with third parties | Personal data plus contractual confidentiality | Degauss + crush |
| Phones and tablets issued to students | Cached mail, photos, messaging apps | Personal data on a device that leaves the institution | Shred or approved device reset before re-issue |
| SIM, ID and library cards | Identity and membership data | High volume, easily lost, low value to destroy | Shred |
| Failed drives from labs | Unsanitisable by software | Highest-risk category, most likely to be missed | Degauss — the only reliable answer |
2. A simple, workable process
- Nominate an owner. One named person — usually the IT manager or the administrative officer — is accountable for media destruction, and a second person countersigns the register.
- Write a one-page disposal rule. No electronic media leaves the campus, is sold, donated or handed to a scrap buyer without being sanitised and recorded.
- Collect at a fixed point. Retired media goes into a locked store, never into general waste. A CCTV drive in a corridor is a real possibility without a rule.
- List before destroying. Record asset tag, serial number, device and media type, and what data it held.
- Separate by media type. Magnetic to the degausser; flash, phones and cards to the shredder.
- Sanitise and destroy. Degauss magnetic media and crush it; shred flash and optical media.
- Record per asset with date, machine, operator and custodian signatures.
- Dispose of scrap through an authorised e-waste recycler and file the documentation.
- Keep the register and review the process once a year, and after any incident.
3. Recommended equipment
| Institution | Magnetic media | Physical destruction | Flash | Approx. monthly volume |
|---|---|---|---|---|
| School or small college | T-1 | PDS-30 | PDS-30 with SSD kit | 1–5 drives |
| College / university central IT | T-1 | PDS-30 or PDS-75 | PDS-88 | 5–20 drives |
| Large university, medical college or research institution | T-1.5 | PDS-75 | PDS-88 | 20–60 drives |
| Institution with frequent exam cycles or multiple campuses | T-1.5 | PDS-75 / PDS-100 | PDS-88 | 60+ drives |
4. Budget guidance
For a school or college that wants a genuine, defensible capability in-house, a T-1 plus a PDS-30 with the SSD kit is a modest capital outlay that covers every media class on the campus. The running cost is essentially nil beyond occasional consumables and an annual machine check. The alternative — outsourcing — is often cheaper still, provided you insist on receiving a signed destruction register every time. Both approaches are defensible; having no process at all is not.
For institutions with a very low volume, our data destruction service is usually the better economic choice. You get a signed register, a completed certificate and no capital outlay — and the process still exists, which is what an audit asks about.
