Editorial, Sources and Quality Assurance

Who is Responsible for the Content

The Preparaio editorial team, as part of the operator's staff, is responsible for all guide content — not a named individual or an external review body. Information on exam format, duration, scoring, and passing rules is cross-referenced with the official documentation of the exam providers; this cross-referencing is a source check, not an accredited expert review.

Use of AI Tools

We use AI tools for drafts, structuring, and translation into our 15 languages. Exam facts are not taken from model knowledge but are sourced from official documents and checked against these sources during cross-referencing. Where information cannot be clearly substantiated, we openly state it as dependent on the examination center rather than specifying it.

Technical Quality Assurance

Before each publication, automated checks are performed: source fields and review dates must be present, fact-heavy articles require at least one primary source, known outdated formulations are blocked by test rules, and all 15 language versions must be complete. If any of these checks fail, the content is not delivered.

Editorial Principles

• Primary Sources First

  Every statement regarding exam format, duration, scoring, or passing thresholds comes from the official documentation of the respective exam provider or competent authority. Secondary sources, forums, and experience reports do not replace them.

• No Promises We Can't Keep

  We do not state success rates, guaranteed results, or fabricated participant numbers. Prices, dates, retake rules, and recognition issues depend on the examination center; we explicitly indicate this instead of estimating figures.

• Visible Source and Format Status

  Every guide article visibly shows when it was last checked against its sources, what exam/format version it refers to, and which primary sources were used. If a provider changes its format, we update the affected articles and adjust the version.

• Corrections Welcome

  If information is no longer correct, we correct it. The editorial team accepts feedback via the contact form; verifiable corrections are implemented promptly and noted in the article's change log.

Primary Sources Used

• g.a.s.t. — Deutsch-Test für Zuwanderer (DTZ): FAQ und Prüfungsformat
• BAMF — Abschlussprüfung im Integrationskurs (DTZ)
• ETS — TOEFL iBT Content & Structure
• ETS — TOEFL iBT Scores verstehen
• IELTS Partners — IELTS Academic Test Format
• IELTS Partners — IELTS Scoring in Detail
• telc — Zertifikat Deutsch / telc Deutsch B1
• Europarat — Gemeinsamer Europäischer Referenzrahmen (GER/CEFR)

These sources are authoritative. In case of discrepancies between our content and the official documentation, the official documentation of the exam provider always applies.

Update and Correction Process

All guide articles are fully reviewed against official sources at least semi-annually. If a provider announces a format change — such as ETS for the TOEFL format starting January 21, 2026 — we revise the affected articles immediately on the effective date instead of during the regular cycle. Every content correction is documented within the article with a date and brief description.
