Editorial Policy

How LexFizz researches, writes, and reviews every piece of English learning content we publish.

Our Mission and Editorial Values

LexFizz exists to provide accurate, practical, and permanently free English learning resources to students and teachers worldwide. Every article, exercise description, and example sentence on this site is created with one goal: to genuinely help learners improve their English.

We hold ourselves to strict editorial standards. We do not publish content to chase traffic, pad word counts, or rank for keywords at the expense of clarity. Every page must earn its place by delivering real educational value to a real reader.

Core principle: If a piece of content would not help an ESL learner sitting in front of us, it does not get published.

How Content Is Created

All content on LexFizz is produced by ESL/EFL specialists with direct teaching experience. Our writers draw on formal training in English language teaching (CELTA, DELTA, or equivalent), classroom experience at multiple levels, and ongoing reference to recognised linguistic authorities.

Primary references used in content creation include:

Vocabulary examples are drawn from authentic language use and are verified against at least one corpus reference (British National Corpus or COCA) to ensure naturalness and currency.

Our Review Process

Before any article or exercise description is published, it goes through a structured review process:

Update and Correction Policy

Language evolves and so does our understanding of best practice in language teaching. LexFizz content is reviewed on an annual cycle. The dateModified date shown in the page metadata and JSON-LD schema reflects a genuine review or update — we do not change this date as a cosmetic SEO tactic.

If you spot an error — a factual mistake, a misleading example, or a broken exercise — please contact us. Corrections are assessed within 7 days and applied immediately when confirmed. Significant corrections are noted in the article where appropriate.

Independence and Sponsorship Disclosure

LexFizz is fully independent. We have no affiliate relationships, no sponsored content, no paid placements, and no advertising partnerships. No third party has ever paid for editorial coverage, a positive review, or a link on this site.

All exercise and content recommendations are made on educational merit alone. If this ever changes, we will disclose it clearly at the top of the relevant page, in full compliance with ASA and FTC guidelines.

LexFizz earns no revenue from content. The site is funded independently to keep it free and unbiased for every learner.

Frequently Asked Questions

Who writes the content on LexFizz?
All content on LexFizz is written by ESL/EFL specialists with direct classroom teaching experience and formal English language teaching qualifications (CELTA, DELTA, or equivalent). Writers are required to verify all grammar rules and vocabulary examples against authoritative references including the Council of Europe CEFR, Oxford 3000, and Cambridge Grammar of English.
Does LexFizz publish sponsored or paid content?
No. LexFizz has no affiliate relationships, sponsored content, paid placements, or advertising partnerships of any kind. Every article, exercise, and recommendation on this site is made solely on educational merit. The site is funded independently and earns no revenue from its content. If this ever changes, it will be disclosed clearly on the relevant page.
How do you ensure grammar rules on the site are accurate?
Every grammar rule and language example is verified against at least one authoritative reference: the Cambridge Grammar of English, Swan's Practical English Usage, or the Council of Europe CEFR. Where authoritative sources differ (e.g., on prescriptive vs. descriptive usage), we note the variation and recommend the standard form for learners preparing for exams.
How often is LexFizz content updated?
Content is reviewed on an annual cycle. The dateModified date shown in each page's metadata reflects a genuine review or substantive update — it is never changed purely for SEO purposes. If language guidance evolves or an error is discovered, corrections are applied immediately and the modification date is updated to reflect the real change.
How are CEFR levels assigned to exercises and articles?
CEFR levels (A1–C2) are assigned after reviewing the vocabulary load (cross-checked against the Oxford 3000 and NGSL frequency lists), grammatical complexity, and assumed background knowledge against published Cambridge Assessment CEFR descriptors. We do not assign levels arbitrarily — each level assignment is a deliberate pedagogical decision.
What should I do if I find an error in a LexFizz article?
Please use our contact page at lexfizz.com/contact/ to report the error. Include the page URL and a description of the issue. All error reports are assessed within 7 days. Confirmed corrections are applied immediately, and significant changes are noted in the article. We genuinely value reader feedback as part of our quality process.
Does LexFizz use AI to generate content?
LexFizz content is produced by human ESL specialists. Any AI-assisted tools used in drafting are subject to the same editorial review process as all other content: fact-checking against authoritative references, example verification, level-checking, and clarity review. No content is published without human expert oversight and sign-off.
What vocabulary references does LexFizz use?
Our primary vocabulary references are the Oxford 3000 and Oxford 5000 (curated high-frequency word lists from Oxford University Press) and the New General Service List (NGSL), a corpus-based frequency list. These are cross-referenced to ensure that vocabulary choices are both high-frequency and level-appropriate. Corpus data from the British National Corpus (BNC) is consulted for naturalness checks.
How does LexFizz avoid thin or low-quality content?
We apply a strict anti-thin-content policy: articles must meet minimum word counts, include unique and verified examples, address a genuine learner need, and provide practical guidance that goes beyond surface-level summaries. Content that merely restates what is already widely available is rejected unless it offers a distinct teaching angle or level-appropriate treatment.
Is LexFizz content suitable for exam preparation?
Yes. Grammar guides and vocabulary resources are aligned to Cambridge Assessment CEFR descriptors and reference exam requirements for IELTS, Cambridge B2 First, C1 Advanced, and TOEFL where relevant. Level badges on each article and exercise indicate the corresponding CEFR band. LexFizz is a supplementary practice resource and is not an official exam preparation course.
