A great deal of senior technology work is covered by confidentiality clauses: unreleased products, client systems, security work, proprietary models. The good news is that the Tech Nation Digital Technology endorsement is judged on your individual impact and its scale — a thing that lives in your account of it and in the testimony of people who witnessed it — not on your ability to hand over the underlying artefacts. You are never asked to breach an NDA to qualify.
Why is a written description enough when the work is confidential?
Because the endorsement criteria ask what you did and how much it mattered — not for a copy of the code, the contract or the dashboard. An assessor reading your case is forming a judgement about the significance of your contribution. That judgement can be reached from a precise, attributable narrative: what the problem was, what you specifically built or led, and the measurable result, expressed at a metric level. "I led the team that cut fraud losses by 38% across a payments platform serving several million users" carries weight without naming the client, exposing the system, or attaching anything privileged.
The recommendation letters do heavy lifting here. Three letters sit outside the ten-document evidence limit, and a senior referee who directly witnessed your work can confirm your role and its scale in their own words. Their testimony is treated as ordinary supporting evidence — one credible signal among several — precisely because it does not depend on any confidential file being disclosed.
How do you actually present NDA-bound achievements?
The task is to convert what you cannot show into something you can attribute. In practice that means:
- Metric-level figures. State scale, growth, users, uptime, cost saved or revenue influenced as numbers or percentages, without naming the underlying client, product or dataset.
- Redaction. Where a document is otherwise usable, redact names, logos and identifiers and submit the redacted version. A redacted artefact is still an artefact.
- Referee corroboration. Ask each of your three referees to confirm the specific contribution and its scale from their own vantage point, so the claim is witnessed rather than merely asserted.
- Public proxies. Where any part of the work later became public — a released feature, a press mention, a conference talk you were cleared to give — use that as a non-confidential anchor for the confidential whole.
Your personal statement and CV then tie these together into one attributable story. The aim throughout is that a reader finishes your case understanding exactly what you contributed and how large it was, without you having disclosed a single protected detail.
What is the common mistake applicants make?
The most common error is retreating into vagueness. Faced with an NDA, applicants write "worked on a large-scale confidential platform for a major client" and leave it there, believing that anything more specific would breach the agreement. It does not — and the vagueness is exactly what triggers an "insufficient evidence of individual impact" outcome. Confidentiality protects identities and artefacts, not your own attributable metrics. You can almost always say how big, how much and what you personally did without naming anything protected.
The mirror-image mistake is over-disclosure: attaching material you were not cleared to share in the hope it strengthens the case. It does not strengthen it, and it is never worth the professional or legal risk. The disciplined middle path — precise on your contribution and its scale, silent on protected specifics — is both safe and stronger.
How does the £200 Fit Assessment help with NDA-bound work?
Deciding which of your confidential achievements can be told in an NDA-safe way, and how, is the hardest part to judge alone. The £200 Fit Assessment scores your profile out of 20 and maps each achievement to the evidence you can actually present — flagging where a metric-level description, a redaction or a referee letter carries the point. You receive a component-by-component breakdown, a 10-document evidence plan, a letter and referee strategy, and a 45-minute review call to walk through it. It is credited in full to any package within 14 days.

Frequently asked questions
Yes. Assessors read a case built on attributable description, not on confidential artefacts. You describe your individual contribution and its scale in your own words and through recommendation letters, using redacted or metric-level evidence where the raw material cannot be shared. This is a widely used approach, not a guaranteed outcome — the case still has to meet the criteria.
Not by itself. The endorsement is judged on your individual impact and its scale, which can be described in words and confirmed by referees who witnessed it. Confidential work is common among senior technologists, and a clearly attributed, metric-level account is treated as ordinary supporting evidence rather than a lesser substitute.
Redacted documents, metric-level figures (percentages, scale, growth, users, uptime) without naming the underlying client or system, public or de-identified references to the outcome, and recommendation letters from senior people who can confirm what you did. The maximum is 10 documents of up to 3 sides of A4 each; the CV and 3 recommendation letters sit outside that count.
The £200 Fit Assessment scores your profile out of 20, maps which of your achievements can be evidenced in an NDA-safe way, and produces a 10-document evidence plan plus a letter and referee strategy. It includes a 45-minute review call and is credited in full to any package within 14 days.
