zero LEARN

How does Zero keep the scoring honest?

Zero scoring is calibrated against real internal evaluation frameworks. Reviewers are verified top-1% professionals. Data is anonymized for public use. Every receipt is traceable to a verified reviewer.

Who evaluates the work?

Reviewers must demonstrate senior-level output in the same domain as the task. We verify their role history, their public output, or their verified industry ranking. A random sample of reviews is audited weekly. Reviewers who drift from the rubric are recalibrated or removed.

How is data handled?

Submissions are stored encrypted. Recruiters see only the receipt summary, not raw data. For public case studies, students are anonymized and universities are referenced only after written clearance. Aggregated stats use ranges until exact counts are approved.

What happens if a score seems wrong?

Every receipt includes a dispute link. A second reviewer re-evaluates the submission within 5 business days. The outcome is binding and logged. If a pattern of bad scores emerges for a particular reviewer, we audit their entire history.

Frequently asked questions

Who scores the submissions?
Verified professionals ranked in the top 1% by performance data in their field. Each reviewer must demonstrate current or recent senior-level output in the same domain as the task.
How is scoring calibrated?
The rubric for each task is built from internal evaluation frameworks used by the company that sourced the task. We do not use generic rubrics.
What data does Zero collect?
Task submissions, rubric scores, reviewer feedback, and basic profile data (name, email, education). We do not track browsing behavior across the web.
How is data anonymized for public materials?
Students are never named in public case studies. Universities are anonymized until explicit written clearance is given. Aggregated data is reported in ranges, not exact counts, until cleared.
Can students dispute a score?
Yes. Each receipt includes a dispute channel. A second reviewer evaluates the dispute within 5 business days.
How are reviewers verified?
Reviewers submit proof of performance (senior role, notable output, or verified industry ranking). Zero audits a random sample of reviews weekly.
